聲音有多大?小米空氣清新機各個檔位噪音詳細

http://news.cnyes.com/20141219/聲音有多大小米空氣凈化器各個檔位噪音詳細-183313358376110.shtml

小米空氣清新機的推出受到了用戶極大的關注,899元的價格,對PM2.5可達99.99%的過濾凈化效果都極具震撼力,那這款品在各個工作檔位的工作聲音和功耗有多大呢?下面就讓我們一起看看。

空氣清新機的工作原理是將污濁的空氣吸進,然后經過初效、HEPA、活性炭三層濾網將空氣中的可吸入顆粒物和有害氣體進行過濾、吸附,最後將潔凈的空氣送回室內。為了讓室內每個角落的空氣都得到凈化,要形成空氣對流,製造全屋空氣大循環,這要求空氣清新機吸進與送出空氣時有足夠的風壓,因此也會生一定的工作聲音。完全靜音的空氣清新機因無法形成足夠的空氣過濾量,是無法起到空氣凈化效果的。

小米空氣清新機各檔位的工作聲音是多少?

小米空氣清新機有AUTO智能自動化、睡眠靜音和高速凈化三種工作模式,AUTO智能自動化又分為弱檔、中檔和強檔模式。其中,睡眠靜音模式的工作 聲音是32dB,AUTO下的弱檔模式45dB,中檔模式50dB,強檔模式60dB,高速凈化模式68dB。那麼,這些數字到底代表做大的聲音感受呢? 據檢測,家庭中電視機、收錄機所生的聲音可達60至80dB,洗衣機為42至70 dB,電冰箱為34至50 dB(數據來自人民網)。

睡眠靜音模式主要是用於夜間睡眠時使用,功率為6w,32dB的聲音就像寧靜沙漠的夜晚,有風吹過耳邊。AUTO(自動)模式(包含弱、中、強三 檔),自動檔運行下功率相當於飛利浦節能燈泡的用電量(10w到30w)。弱檔模式45dB,就像辦公室同事小聲怯怯私語的聲音,功率為8w。中檔模式 50dB,相當於正常大家談話的聲音,功率為13w。強檔模式 60dB,與洗衣機的工作的聲音相當,功率為31w。高速凈化模式的聲音為68dB,相當於10米外經過的汽車的聲音。與其他同檔位的空氣清新機相比,這 個是小米空氣清新機獨有的功能。高速凈化模式只有在用戶手動觸發的情況下才能開啟,持續時間為15分鐘,高速模式開啟15分鐘后會自動切換為自動模式。該 模式的功率為75w。

建議平時一直將小米空氣清新機的工作模式保持在AUTO自動模式,這樣一旦控制空氣質量下降,凈化器可以及時做出反饋調整不同的風速檔位,保持您的室內空氣潔凈,自動狀態大部分時間下都會在低檔速運行,只有當凈化器檢測到室內空氣質量出現問題的情況才會提升檔位。

什麼時候使用高速凈化模式?

設計AUTO模式的原因是應對某些極端環境下的空氣凈化需求,比如在家裏抽煙怕被老婆發現,室內PM2.5污染爆表,需要快速凈化到純凈空氣狀態。 高速凈化模式只能通過手動或者智能家庭APP控制激活,工作時間設定為15分鐘,可以用最短的時間將全屋空氣凈化一次,之后就會自動回到安靜的AUTO模 式。如果有同學覺得68dB聲音有些大,可以在外出時使用,回家前先遠程遙控打開一下小米智能家庭,把家裏的空氣徹徹底底的凈化一遍,這樣回家就可以享受 好空氣。

小米空氣清新機的CADR值高達406(空氣凈化效率,是國際公認衡量空氣清新機的權威指標),在高速凈化模式下凈化一次28-48平方米的面積僅 需要12分鐘,之后就會進入安靜的AUTO模式。而CADR值僅有200多的低端空氣清新機全速工作30分鐘,也未必能完成一次全屋的完全凈化,要想達到 相同的凈化效果,用戶需要等待更長的時間才能進入安靜模式。

科普:如何正確測量噪音值

對於空氣清新機工作噪音的測試有明確的國家標準,在測試噪音時,直接將測量設備置於凈化器頂部出風口處讀取數據顯然是不正確的。根據《聲學家用電 器及類似用途器具噪聲測試方法 第1部分:通用要求》GB/T 4214.1-2000中的規定,“對於自由放置的落地式器具,包括嵌入式器具,測量表面是帶有九個測點的矩形六面體”,如下圖:

圖中藍色圓點為傳聲器的位置,通過對這9個點位的測量,讀取數值,並按照專業的計算方法得出品的準確噪音值。由此可見,正確測量一款品的噪音值需要專業的方法和設備,通過非專業方式測量得出的數據,是無法正確反應品噪音值的。

小米就空氣清新機抄襲事件作出回應



http://info.hvacr.hc360.com/2014/12/151539542031.shtml

慧聰空調制冷網就日本淨化器廠商巴慕達暗指小米抄襲產品設計,小米旗下的智米科技發表聲明做出回應,稱小米空氣清新機有著完全不同的設計。對於巴慕達公司的聲明和部分業內不負責任言論深感遺憾。

日本空氣清新機廠商巴慕達及其品牌創始人兼產品總設計師今天發布聲明,稱小米科技發布的空氣清新機,該產品從外形,內部構造以及宣傳文案等都與本巴慕達在今年初發布的AirEngine安之風空氣清新機高度相似。

13日下午小米旗下智米科技發表公開聲明,稱小米空氣清新機在技術、外觀等方面與巴慕達的AirEngine空氣清新機的產品有著完全不同的設計。對於巴慕達公司的公開聲明和部分業內不負責任、有失專業水准的言論深感遺憾。

以下為聲明全文:

智米是一家剛成立不久的創業公司,但從創辦之日起,我們就非常尊重知識產權且注重知識產權的積累。目前,我們已向國家專利局提交了31項專利申請,其中最為重要的就是在風扇、風道、和整機結構等產品的關鍵核心部件或設計環節的專利。

我們的產品並沒有抄襲包括Balmuda在內任何企業的專利設計及技術,我們在技術、外觀等方面與Balmuda的AirEngine空氣清新機的產品有著完全不同的設計。對於Balmuda公司的公開聲明和部分業內不負責任、有失專業水准的言論,我們深感遺憾。

在研發小米空氣清新機過程中,我們嘗試了100多種設計,最終選定了我們認為最為合理的優化方案。在家電行業中,由於空氣動力學等物理規律的限定,以及制造工業長期積累的最優化設計方案等因素,很多品類都有相對成熟的外觀及結構設計理念,如冰箱、電視、空調等產品的外形相似度偏高。我們並不認同“為不同而不同”、“重復發明輪子”式的爭論,而是希望把精力投入到不斷打磨、持續優化產品功能、功效及體驗中去。

同時,我們選用了業內最頂尖的零組件及濾芯材料。智米是小米智能生態鏈企業,認同小米的價值觀,我們希望用真材實料做出高性能的產品,去除行業不合理的暴利,讓每個人、每個家庭都能享受清新的空氣和健康的生活,惠及大眾、造福社會。

為此,我們一直以開放姿態,希望與所有有志於此的行業伙伴通力合作,為優質空氣清新機產品的家庭普及率提升不斷努力,共同推進行業進步,做大空氣清新機整體市場蛋糕。

小米空氣清新機噪音為啥那麼大



北京新浪網 http://news.sina.com.tw/article/20141215/13601949.html

近日,有媒體發現,小米送測的空氣清新機共提供了三種工作方式,分別為自動、睡眠、高速模式。睡眠自然不用多說,非常安靜;自動模式稍大一點,但也完全可以接受;但高速模式下,堪比「飛機起飛」,實測噪音達到了70db。

一個空氣清新機,為啥會有這麼大的噪音?剛剛,小米空氣清新機主創智米公司在微博給予了回應,他們表示,官方數據是32db-68db,媒體得出的數據在誤差範圍內,並且這些數值都在國家標準規定的範圍內。

智米表示,小米空氣清新機使用了使用了2個風機,而且其中1個是能製造強大風壓的「后傾離心風機」(風壓大,效率高,噪音偏大,iQair、安利等高性能凈化器使用),和使用1個「前傾離心風機」(風壓小,效率低,噪音小,飛利浦、夏普等普通性能凈化器使用)相比,確實不佔優勢。

小米空氣清新機的核心要素是「小體量,高性能」,為此不得在噪音方面做出一些讓步。

產生最大噪音的「高速模式」,會在15分鐘后自動切換為「自動模式」(自動模式的噪音很低,並且會在3個不同風檔間自動切換)。

並且由於產品具有智能遠程控制功能,如果在回家前,點擊運行「高速模式」,一進家門,就可以享受潔凈的空氣和靜謐的環境。

小米式創意「參考」日本名牌?「平價」智能空氣清新機


▲ 小米手機搖控空氣清新機,它是支援 Wi-Fi 802.11 b/g/n,賣價 $899 人民幣(約 $1,100 港幣)


▲ 這是日本品牌 Balmuda 的空氣清新機 AirEngine ,有網友覺得設計相當接近,售價為 $5,499 人民幣(約 $6,900 港幣)

- http://www.eprice.com.hk/nb/talk/1141/23404/1/

應該有不少網友留意小米的「新品溝通會」,主題「等風來」。意料之外,小米轉投家電市場,推出自家的「智能空氣清新機」。資訊公開後就傳來網友批評,設計「參考」日本牌子。價錢方面小米仍然主打「抵食夾大件」,低價錢高規格,你會不會考慮小米的「智能空氣清新機」?

小米推智能空氣清新機!網友指設計「參考」日本牌子 Balmuda

既然是小米出品,當然有一定的「智能」,這架小米空氣清新機是可以用手機控制,亦會智能通知手機空氣淨化程度、濾沁什麼時候需要更換,亦可以設定「定時淨化」功能。但網友很快發現「小米空氣淨化機」的設計和日本牌子 Balmuda 相當接近,就連機身大小亦是差不多。

小米空氣清新機算不算高CP值?版主就給例子大家 :

小米空氣清新機的出風量: 409 立方米/ 小時,超過 300立方米/小時的空氣清新機最低限度售價為 $6,000 ~ $7,000 ,小米空氣清新機賣價 $899 人民幣(約 $1,100 港幣)。比較同級裝置廉價八成之多!而 28.4 ~ 48.7 平方米的面積內更可以做到 12 分鐘做到一次完全淨化,對於香港的蝸居是十分足夠。

小米空氣清新機暫時只供中國大陸售賣,於12 月 16 號正式開賣。

港外籍留學生 研發室內空氣監察裝置



http://startupbeat.hkej.com/?p=11321

自己在家無故打噴嚏或咳嗽,又或者孩子晚上輾轉難眠,這可能是家居空氣含有害物質,早年亦有研究指室內空氣或藏致癌危機,香港有外國留學生與同學研發智能裝置「優呼(uHoo)」,能監察家居空氣質素,並對個人健康作分析。

uHoo外形很像平日用的咖啡杯,內置的5個感應器能檢測到空氣中的微灰塵(PM2.5)、家居用品(例如油漆、清潔劑)散發的化學物質、二氧化碳、温度及濕度,並可把數據經由無線網路直接傳到雲端系統,用家即使在辦公室,亦可以透過手機App,得知家中空氣質素,及提供環境數據,對用家健康進行分析及建議。

uHoo在今年8月創辦,聯合創辦人兼CEO Dustin Jefferson Onghanseng,他是菲律賓人,現就讀香港科技大學工商管理碩士課程,本身患有過敏性鼻炎的他,有一天在宿舍與同學閒聊時,激發他研發uHoo的念頭。現時uHoo正在網站indiegogo籌款,目標是籌3萬美元,但此舉只為宣傳用途,uHoo正從其他途徑集資,產品預計在明年6月發售,每個售129美元。

Dustin昨天接受StartupBeat訪問表示,uHoo共有6名成員,其中3名為聯合創辦人,分別是香港人、日本人及菲律賓人,他們都是科大MBA學生,由外地來港求學,有緣遇上志同道合的同學便留下創業。

Dustin曾為《財富》500強企業及中小企的管理層擔任管理顧問,在新加坡國立大學讀書時,曾經創業但因欠缺資金而失敗收場,創業的理想仍然留在他心裡,之後他決定放棄在大企業的高薪厚職,來香港報讀碩士及創業。

他希望可以改善人類健康,發展保健產業,「健康護理不只是診斷及治療,健康護理可以是偵查、預告和預防」。

New at Summit Racing Equipment: Green Air Filters



Green Filter elements use a pre-oiled, double-layer woven cotton filter that is pleated to provide 10-15% more filtration surface than a typical paper element. According to Green Filter, that means measurable improvements in power, throttle response, and fuel mileage versus a paper element.

If Green Filter is right and the average vehicle uses 20 paper air filters over 100,000 miles, that’s a lot of money being thrown away, not to mention the environmental issues all those filters cause. Because a Green Filter is reusable and carries a lifetime warranty, one filter can last the life of the vehicle. Just clean the filter every 30,000 miles with Green Filter’s biodegradable cleaner, then re-oil with the recommended filter oil.

All Green Filter air filters have a stainless steel mesh around the filter element, plus a perimeter rubber seal molded in a four-step process that assures an airtight seal and prevents rubber from seeping onto the element and restricting airflow.

Summit Racing offers Green Filter OEM replacement elements for many late model domestic and import vehicles, plus universal round and conical elements for performance applications, air cleaner assemblies, crankcase breathers, and element cleaner/oil.

立法會五題:改善空氣質素

http://www.info.gov.hk/gia/general/201411/26/P201411260683.htm

以下為今日(十一月二十六日)在立法會會議上郭榮鏗議員的提問和環境局局長黃錦星的答覆︰

問題:

  本會環境事務委員會轄下有關空氣、噪音及光污染事宜小組委員會已於本年二月向該事務委員會提交報告,就政府改善空氣質素等事宜提出多項建議。關於政府就該等建議承諾進行的跟進行動的進展,政府可否告知本會:

(一)鑑於空氣質素指標按法例須每五年檢討最少一次,而當局亦承諾於明年年底前,向本會環境事務委員會匯報擬備檢討方法的進展,該項工作的進展為何,包括當局會否在匯報進展前定期向事務委員會提交進度報告,以便第一次檢討能在二○一九年啟動;當局打算按甚麼準則評估空氣污染對健康的風險;

(二)鑑於當局表示環境保護署正利用路邊遙測設備及功率機進行廢氣測試,加強管制汽油和石油氣車輛的廢氣排放,而運輸署亦計劃使用功率機為進行年檢的車輛測試其廢氣排放,該兩項工作的進展及成效為何;該兩個部門有否互相合作,以提升該等測試的成效;如有,詳情為何;如否,原因何在;及

(三)鑑於當局早於去年中已表示正提升一套稱為「大氣污染物在香港的傳播」(即『PATH』)的空氣質素模型系統,為何新系統需於明年一月才推出,以及有關工作現時的進度為何;當局會採取甚麼措施,以協助大學、環保團體等研究機構了解新系統?

答覆:

主席:

  環境局已在本年七月十七日的環境事務委員會會議上,對「有關空氣、噪音及光污染事宜小組委員會」提交報告的建議作回應和介紹政府最新的跟進工作。至於郭議員的提問,我的回覆如下:

(一)世界生組織(世)建議不同地區在制定空氣質素指標時,必須根據實際情況,並因應當地空氣質素對人體健康的風險、切實可行的技術、經濟、政治和社會等因素。世亦有建議中期目標,以循序漸進方式減少空氣污染。

  香港按照世的建議,並參考世建議的中期和最終目標,以及其他先進地區的標準制定了二○一四年實施的新空氣質素指標。新的空氣質素指標與美國和歐盟等先進國家的標準大致相若。為保障公眾健康和持續改善空氣質素,《空氣污染管制(修訂)條例》亦訂明,我們會最少每五年檢討空氣質素指標一次,用達致世空氣質素指引內最終標準的長遠目標。

  日後檢討空氣質素指標時,我們會繼續按照上述考慮因素進行。具體來說,我們會評估空氣質素改善措施的成效、珠江三角洲地區的排放趨勢、減排技術的發展和空氣污染對健康的風險等等。

(二)維修不善的汽油及石油氣車會排放過量的氮氧化物和碳氫化合物,引致路邊二氧化氮濃度偏高。由於商業車的行車里數遠高於私家車,過往監測顯示有過量廢氣排放問題的石油氣的士和小巴分別約佔差不多八成和四成半,遠高於私家車的百分之七。

  催化器和含氧感知器失效是導致的士和小巴排放過量廢氣的其中一個主要原因。政府去年十月至今年四月期間,一次過資助13 942輛的士和2 881輛小巴更換催化器及含氧感知器,吸引約八成合資格的車輛參加。今年上半年,即使由於氣象因素導致塔門空氣監測站錄得的臭氧平均濃度比去年同期上升約百分之六,從而加快車輛排放的氮氧化物轉化成二氧化氮,但期內路邊空氣監測站錄得的二氧化氮平均濃度較去年同期下降了百分之六。這「不升反降」的結果顯示我們的減排措施開始發揮正面的作用。

  另外,環保署由本年九月一日起,以路邊遙測儀器檢測汽油和石油氣車輛的廢氣,並要求排放過量廢氣車輛的車主於指定時間內修妥車輛,並通過指定的廢氣測試才可繼續行使,否則會吊銷其車輛牌照。加強管制廢氣排放有助車主養成妥善維修保養車輛的習慣。

  在今年九月和十月,路邊遙測儀器共檢測了約59 000部車輛的廢氣,約佔全港汽油和石油氣車輛的十分之一。當中排放過量廢氣的的士、小巴和私家車佔同類被檢測車輛總數的百分比,分別為百分之3.3、4.8和0.5。由此可見有過量廢氣排放問題的的士和小巴已大幅減少。

  環保署正與運輸署合作研究在的士及小巴每年續牌的檢測中,加設功率機測試廢氣的可行性,當有廢氣問題車輛未能按環保署指示在指定時限內通過廢氣測試,運輸署會取消該車輛的牌照。

(三)「香港大氣污染物傳輸模型系統」(PATH)是用作評估空氣污染排放物對特定地點空氣質素影響的模型系統,廣泛應用在環境影響評估研究。整套系統包括氣象、化學及傳輸組件,各自涉及非常複雜的科學理論和計算。評估空氣質量的影響須考慮空氣污染排放物的性質、氣象資料、化學反應、地形及背景空氣質素等。

  為更有效率完成系統更新,環保署在二○一三年八月邀請相關的學者成立專題工作小組,深入研究系統程式和組件,訂定驗證和優化方案和核實成果。在更新系統的過程中,我們要顧及驗證和優化等工作。這些工作需要長時間進行,並小心核對資料。有關工作預計在二○一五年年中完成。我們會聯同專題工作小組在推出新系統前,向相關人士詳細介紹其運作及應用。

城市空氣污染 肌膚衰老元凶


住城市,老得快。以往一般都認為紫外線是加快肌膚衰老的元凶,但越來越多研究顯示,空氣污染跟紫外線具同等殺傷力。最新調查發現,住市區的女性,因空氣污染嚴重,比起住郊區的女性,皮膚衰老會快10%。

城市空氣中含有多達224種污染物,這些微小污染物粒子能夠進入皮膚,摧毀細胞和角蛋白,削弱皮膚天然屏障,破壞保持肌膚彈性的膠原,令皺紋加快出現。

城市女郎較易現老人斑 有護膚品生產商在中國做研究,200名30至45歲女性,部份住在類似北京的大城市(圖),部份住郊區,生活方式和日曬程度相近,發現城市女性肌齡較大。德國400名女性的研究亦發現,城市女郎現老人斑的機率高20%。

2013年香港空氣質素 監測結果報告

http://www.info.gov.hk/gia/general/201410/31/P201410310787.htm

環境保護署(環保署)今日(十月三十一日)發布《2013年香港空氣質素》監測結果報告。

  報告概述環保署的空氣監測網絡,包括11個一般監測站和3個路邊監測站,於二○一三年所收集的空氣質素監測數據。網絡監測多種空氣污染物,包括二氧化硫、氮氧化物、二氧化氮、臭氧、一氧化碳、總懸浮粒子、可吸入懸浮粒子(PM10)、微細懸浮粒子(PM2.5)、鉛和毒性空氣污染物。

  環保署發言人表示,監測結果顯示香港的空氣質素近年來已逐漸改善。隨香港特別行政區政府與廣東省政府聯手在珠江三角洲區域實施多項減排措施,近年本港空氣中的氮氧化物、二氧化硫和可吸入懸浮粒子的水平均呈現下降趨勢。

  他說:「然而,臭氧的濃度則呈現緩慢上升的趨勢。臭氧是光化學煙霧的主要成分,兩地政府會繼續採取管制措施,改善珠江三角洲地區的光化學煙霧及臭氧問題。」

  香港自從在二○○○年實施了多項新的車輛排放管制措施後,近十年來香港路邊空氣中錄得的氮氧化物、可吸入懸浮粒子和二氧化硫濃度已明顯下降。雖然路邊二氧化氮的濃度在過去幾年仍處於較高水平,但持續上升的趨勢已大致平穩下來。政府現正手推行針對性的管制措施,以降低路邊二氧化氮的濃度。

  報告又顯示,與往年的情況一樣,二○一三年大氣中錄得的一氧化碳和鉛的水平,均遠低於相關的空氣質素指標限值。監測數據顯示香港的毒性空氣污染物與其他主要城市所錄得的情況相若,處於甚低水平。

  發言人強調,政府的空氣質素政策以保障市民健康為大前提,政府會致力改善本地空氣質素。環境局在年二○一三年三月發表了《香港清新空氣藍圖》,詳細闡述香港就空氣質素面對的挑戰及概述各項相關的空氣質素改善政策、措施和計劃。藍圖提供詳細說明各個相關行業的空氣污染改善措施,涵蓋海陸交通、發電廠和非路面流動機械,並尋求深化粵港兩地的合作,以應對區域空氣污染。

調查指珠三角合作減排香港空氣質素漸改善

稿件来源:香港中國通訊社 http://www.hkcna.hk/content/2014/1031/307168.shtml

香港中通社10月31日電 香港環境保護署31日發布《2013年香港空氣質素》調查顯示,香港空氣質素近年已逐漸改善。

報告涵蓋11個一般監測站、3個路邊監測站,測量多種空氣污染物,包括二氧化硫、氮氧化物、二氧化氮、臭氧、一氧化碳、總懸浮粒子、可吸入懸浮粒子、微細懸浮粒子、鉛和毒性空氣污染物。

環保署表示,隨著政府與廣東省合作在珠三角洲區域實施多項減排措施,近年空氣中的氮氧化物、二氧化硫和可吸入懸浮粒子水平均呈下降趨勢。不過,臭氧濃度緩慢上升,反映光化學煙霧問題存在,兩地政府會繼續採取改善措施。

自2000年實施多項新車輛排放管制措施後,近十年香港路邊空氣中的大部分污染物濃度皆已明顯下降,只有二氧化氮濃度處於較高水平,但情況已經受控。政府現正著手推行針對性管制措施,降低相關濃度。(完)

6 ways to combat indoor air pollution

Vacuum, dust, and other ways to clear the air
http://www.consumerreports.org/cro/news/2014/09/6-ways-to-combat-indoor-air-pollution/index.htm | Published: September 26, 2014 08:00 AM

The air inside your house could be five times more polluted than what’s outside, especially during the winter. Cold weather keeps windows and doors shut tight, preventing the exchange of fresh air. Roaring fireplaces are a potential source of noxious soot and smoke. Even scented candles, whether peppermint or pine, can release harsh chemicals.

Those pollutants can trigger a number of ailments, including allergies, asthma, and chronic headaches. Even if you’re symptom-free, it pays to clear the air at home when you're expecting guests because people react differently to contaminants. Here are some effective strategies from the experts at Consumer Reports—and many of them don’t cost a thing. You’ll also find our latest test results for air purifiers, which can provide an added weapon in your effort to breathe easier.

Control the moisture
Water is the cause of so many house problems, including those related to bad indoor air. Too much moisture raises humidity levels above 50 percent, the point at which mold, mildew, and other allergens thrive. That’s why it’s critical to keep out rainwater by maintaining your gutters, leaders, and downspouts. Also make sure that the soil around your house slopes away from the foundation.

Capture the dust
All of those particles you see dancing through the daylight come from pollen, pet dander, and other pollutants. Regular vacuuming prevents dust buildup on carpets, furniture, and other surfaces. Once a week should suffice, although if you have pets that shed a lot, you’ll probably need to clean more often. To find the best vacuum for carpet, bare floors and pet hair, check our full vacuum Ratings and recommendations.

It’s a good idea to dust furniture, blinds, and windowsills before you vacuum. Using an electrostatically charged duster or a damp rag will help minimize airborne particulates. Of course, the less dirt that enters your house, the better. Place doormats at entrances and consider imposing a shoes-off policy.

Switch on your exhaust fans
Routinely replacing the air in your house with a fresh outdoor supply will cut down on contaminants. Exhaust fans are a good source of ventilation, especially during the winter months when windows tend to be closed. Run the bathroom fan after you shower to control mold and mildew. As for the kitchen, our tests have found that vented range hoods remove smoke and odors far better than a fan on an over-the-range microwave.

Contain any chemicals
Remember that many cleaning products are a potential source of contaminants. Always read the labels and follow instructions carefully. In the case of certain cleaners, chemicals are emitted quickly, so use them only in well-ventilated areas. Other products, including paint, release chemicals over time, so look for those that are low in VOCs (volatile organic compounds) and for items that are formaldehyde-free. After using them in a room, keep the windows open with a fan running for several days.

Stamp out smoke and fumes
We all know that smoking cigarettes kills. But what’s less known is that about 3,000 nonsmokers die each year from lung cancer caused by secondhand smoke. So ban smoking in your house.

Wood-burning stoves and fireplaces can also release harmful smoke and soot if they’re not maintained properly. Along with scented candles, incense can send particles into the air that can cause asthma attacks and allergic reactions.

Then there’s carbon monoxide, a more threatening pollutant that claims hundreds of lives each year. Referred to as the silent killer, the odorless, colorless gas can kill without warning if it leaks from a faulty furnace, clothes dryer, or other fuel-fired appliance. Install a CO alarm on every level of your house, including the basement.

Consider an air purifier
Those devices can help clear the air in your house. We wouldn’t have spent almost $10,000 on dozens of test models if that weren’t true. But first you should take the preventative steps outlined above. “Without source control and proper ventilation, using an air cleaner to reduce pollutants in your home is like bailing water out of a leaky boat,” says Elliott Horner, Ph.D., lead scientist for UL Environment (Underwriters Laboratories). Certain environmental conditions may also create the need for supplemental air cleaning. For example, if you rarely open your windows because you live next to a highway or near an industrial site, an air purifier might be helpful.

Top air purifiers from our tests
Consumer Reports tests both room and whole-house air purifiers, which replace the standard filter in a forced-air heating or cooling system. Here are the top three of each type.

Don’t Waste Your Money: Best & Worst Air Purifiers

http://wtkr.com/2014/10/15/dont-waste-your-money-best-worst-air-purifiers/

Air cleaners make claims like “capture 99 percent of allergens and irritants,” “remove allergens like dust, pet dander and pollen,” healthier, fresher air.” Consumer Reports tested 26 portable air cleaners to see how well they work.
Testers pump contaminants into a controlled chamber, dust, as well as smoke. Some of the models tested were slow and to removed the contaminants and not terribly effective. The three poorest performers: Hamilton Beach TrueAir 0483, Hoover model WH10600 and Holmes HAP1200-U.

Consumer Reports says also stay away from electrostatic purifiers because they can emit ozone, which can aggravate allergies and asthma.

And be aware, even the best air cleaner isn’t going to be enough if you’re not very proactive about removing contaminants like vacuuming, dusting, making sure the rooms are adequately ventilated. Those things are actually much more important than just using an air cleaner.

If you still want an air purifier, Consumer Reports says opt for one that uses filters to clean the air. Consumer Reports recommends the Honeywell HPA300for $250. It’s relatively quiet and excels at removing dust, pollen and smoke.

Consumer Reports also tested whole-house filters for homes heated and cooled with forced-air. They replace the standard filter in a forced air system. The 3M Filtrete 1550 for about $30 is very good at removing dust and smoke and is one of the least expensive tested. Like many whole-house filters it will need to be installed by a professional.

識揀淨化機吸一口清新空氣

http://the-sun.on.cc/cnt/lifestyle/20141011/00481_001.html?pubdate=20141011

空氣污染,健康遭殃!尤其是鼻敏感、哮喘等患者,每逢轉季都要活受罪。二氧化碳、可吸入懸浮粒子、甲醛等都是常見的室內空氣污染物,每天我們有不少時間留在室內,想紓緩問題,空氣清新機或許大派用場,專家建議按家居面積及個人需要選購產品,識得揀以後就能呼吸清新空氣!

根據環境保護署轄下的室內空氣質素資訊中心指出,空調樓宇內最常見的室內空氣污染物,包括二氧化碳、可吸入懸浮粒子、甲醛、總揮發性有機化合物及空氣中的細菌。如果樓宇附近有停車場或室內裝設有燃燒爐具(如供應燒烤食品的食肆),一氧化碳及二氧化氮這類燃燒產物的水平,亦可能偏高。除了控制污染源頭、保持空氣流通、注意家居衞生等,還可購買空氣清新機,多管齊下,讓大家呼吸到健康清新的空氣。

按面積選擇

至於空氣清新機的操作原理,一般是由風扇抽入空氣,把當中的懸浮粒子、雜質等,以過濾器隔開,達致淨化效果。香港高等科技教育學院科技學院院長蔡宏教授提醒:「現時並無一件產品能對付所有空氣問題,有的針對空氣中的異味,有的針對懸浮粒子、甲醛等,所以大家應按需要而選購。」

蔡教授補充說:「室內面積是另一個重要的指標,可利用『地板面積』乘『樓底』來計算『有效空間』,然後根據數據選擇產品。若置身在較大空間,我們可採用『機跟人走』的原則,即多放一部空氣清新機,發揮更佳的淨化效果。」
此外,大家亦不要忽視機內濾芯。蔡教授說:「過往曾就這類產品進行研究,新的濾芯當然能發揮最佳效果,但幾個星期後,效果便漸弱。而有些濾芯塗上二氧化鈦,甚至採用納米技術,可令表面的物質不易掉落。因此,大家應參考說明書,注意濾芯有效期限。」

看不見的「空氣雨傘」 用空氣擋雨



您是否覺得一般雨傘的金屬桿加防水布結構不夠拉風呢?目前有一款正在研發中的「空氣雨傘」(Air umbrella),是利用看不見的空氣來擋雨,或能在不久的將來讓您與眾不同!

「空氣雨傘」看起來像一支大型麥克風,主要有3個部分:控制開關位於底部,中間是鋰電池,最上面是燈泡狀的風扇結構。其特色是沒有遮雨的傘面,而是靠鋰電池驅動風扇,以產生氣流阻擋雨滴落下。
風扇產生氣流的速度可視情況調整。目前氣流足夠遮擋一、兩個人,雨小的話,可以擠下更多人。 這種雨傘有3種規格,主要差異是長度和電池使用的時間。第1種專為女性打造,長30公分、重500克、電池可使用15分鐘;第2種是基本型,長50公分、重800克、電池可使用30分鐘;第3種是可伸縮的,可從50公分拉到80公分,重850克、電池可使用30分鐘。其電池可充電並重複使用,壽命為3年。

此雨傘產生的噪音比雨聲還小,但不確定其在有風的情況下能否正常運作。 「空氣雨傘」由來自中國大陸的研發團隊所設計,他們正在眾籌網站Kickstarter募集資金,成品預計在2015年12月上市。

87%居家空氣不合格 呼吸都是在「吸毒」

http://www.uho.com.tw/hotnews.asp?aid=34380

空氣不乾淨 呼吸都是在「吸毒」
俗語說:「病從口入」,所以大家都很注意「吃下肚的東西」必須乾淨。但最新統計數據顯示,「肺癌」已躍居「台灣10大死因」的第一名,無疑證實了「病從鼻入」的可怕!也因此,我們不難理解,如果每天「吸進肺裡的空氣」都很髒,那麼,儼然就跟「吸毒」一樣,時間久了當然會生病!

室內空氣有多毒?竟有87%居家空氣檢驗都不合格!

問題是,很多人根本不知道自己所置身的室內環境「空氣有多髒」!就以每天我們所待時間最長的「居家空間」為例,你知道你家的房子究竟夠「健康」嗎?……根據新光醫院江守山醫師檢測新竹以北66間私人住宅的結果發現,台灣住家的室內空氣不合格率高達87%!其中,有6成的臥房都裝潢過度,導致甲醛嚴重超標;客廳和主臥室所含的揮發性有機物比例則最高;通風不良的浴室也有問題;至於媽媽們最常待的廚房,懸浮微粒污染則最嚴重──這也印證了家庭主婦、職業廚師之所以較常罹患肺病的現象。

注意,空氣污染的3大元兇就是灰塵、二氧化碳、有機氣體!

想要「淨化空氣」,就必須先了解「導致空氣品質不良」的原因何在──簡單來說,造成室內空氣污染的物質大概可以分為三大類,就是:「灰塵」、「二氧化碳」,以及「揮發性有機化合物」(VOCs)。只要能對於它們的成因及來源有初步的認知,就比較能夠防範於未然,避免對於身體造成危害!

• 灰塵(懸浮微粒)→引起呼吸道、心臟血管疾病!

灰塵依顆粒直徑大小分類,通常對身體影響最大的是「小於或等於10um(微米)的懸浮微粒」,因為它可以隨著呼吸作用進入人體的呼吸系統,繼而引發呼吸道相關疾病、心臟血管疾病。而室內空間的主要灰塵來源則包括:吸菸的煙塵、烹煮所產生的黑碳懸浮微粒、建材中的石棉、人造礦物纖維或家中寵物的細毛等。

• 二氧化碳→造成頭昏、嗜睡、注意力無法集中!

室內二氧化碳濃度過高,主要是因為辦公室或其它公共場所有比較多的人聚集、呼吸、吸菸、及其他燃燒行為所致。當室內人口密度過高或是通風效率不佳時,就容易造成二氧化碳濃度累積,同時,其他污染物的濃度也會相對提高,也因此,「二氧化碳濃度」被視為室內空氣品質良窳的最重要指標。一旦室內二氧化碳濃度過高,除了會刺激呼吸中樞、造成呼吸不順,還會導致頭痛、嗜睡、反射力變差、倦怠等症狀。

• 揮發性有機化合物→已被證實會致癌、影響生育!

科技發達,卻也導致有毒的「揮發性有機化合物」充斥。在家中,包括油漆、清潔劑、殺蟲劑、化妝品和香水等,幾乎無所不在。而在辦公環境中,除了裝修建材及家具外,像是經常使用的文具、影印機、印表機等,也都含有大量的揮發性有機物質。其中,又以「甲醛」最常見,也最廣為人知,因為大概有超過三千種的建材中皆有它的存在!而這些有毒物質不僅會對皮膚、呼吸道、中樞神經系統等產生刺激,更已被證實會致癌,甚至導致不孕!

生食讓你擺脫氣喘與過敏

http://cht.naturalnews.com/chtbuzz_buzz002838.html

珍妮青少年的時候在一間工廠工作,由於工作環境的塵土飛揚、空氣環境糟糕,她被醫生診斷出罹患了氣喘;為了過更健康的生活,她辭去了工作並開始慢跑運動,但她的症狀不只沒有消失,反而更嚴重了。

醫生為她做了身體檢查,告知她罹患的是運動誘發型氣喘 (Exercise-induced asthma)。珍妮對於出入醫院檢查、必須使用吸入器和經常性的胸悶感到十分挫折,於是她尋求了一名按摩師的建議,該按摩師主張透過適當的營養來治療,他建議珍妮採取生食並堅持無麩質與牛奶的生活方式。

珍妮照做了之後結果令人驚喜,在很短的時間之內她的氣喘與過敏症狀就無影無蹤了。從那時起,珍妮就保持了這樣的生活方式,現在她已經將近 40 歲,很少感冒、不再有胸悶和呼吸的問題;2012年時她陸續採用過 80-10-10 法則的飲食 (每日 80% 碳水化合物、10% 蛋白質和10% 的脂肪) 和一日30根香蕉的飲食法,成效都很不錯。

除了擺脫氣喘與過敏之外,珍妮表示生食飲食也幫助她消除了其他健康問題,像是關節炎和便秘。珍妮現在以 Raw Jenni 的名字開設了自己的 Youtube 頻道與臉書粉絲團繼續推廣生食的好處。

中度污染別害怕 五大空氣清新機來解憂

原標題:中度污染別害怕 五大空氣清新機來解憂 http://homea.people.com.cn/n/2014/0923/c41390-25713883-6.html

引言
  昨天北京發布了中度污染的空氣污染情況,天氣一直陰沉,灰霾的天氣下,人們的心情也受到一定的影響。大家可還記得年初的重度霧霾天氣,給我們的生活和健康造成了嚴重影響,PM2.5對人們的健康影響是巨大的,粒徑在2.5微米以下的細顆粒物,直徑相當於人類頭發的1/10大小,不易被阻擋。被吸入人體後會直接進入支氣管,干擾肺部的氣體交換,引發包括哮喘、支氣管炎和心血管病等方面的疾病。
中度污染別害怕 五大空氣清新機來解憂
  人們對於PM2.5的認知來源於嚴重的霧霾天氣,而這種天氣也讓空氣清新機成為了家喻戶曉的產品。目前空氣清新機行業發展迅速,各個品牌相繼加入到空氣清新機的行業中,各種外觀設計,各種功能的創新,為行業發展做出了貢獻,但是,雜亂無章的競爭加劇了行業混亂的現像。而當下,空氣清新機行業的標准商在研究制定中,所以,消費者就不得不根據自己的經驗和品牌知名度進行選擇。
  選擇空氣清新機最主要的就是看清新機的一次性清潔效率,你可以根據你的使用面積進行選擇。空氣清新機的HEPA濾網是需要更換的,更換的年限每款產品都有所差別,所以,購買空氣清新機是需要考慮二次消費的。

「鳳凰」逼近空氣污染爆錶

【太陽報專訊】【本報訊】 https://hk.news.yahoo.com/鳳凰-逼近空氣污染爆錶-223022707.html

颱風「海鷗」遠去,又有熱帶風暴「鳳凰」臨近。「鳳凰」昨午集結在馬尼拉以北約四百七十公里,預料向西移動,時速約十四公里,將在本港八百公里範圍附近掠過。本港昨日天氣酷熱、風勢微弱,令空氣中的污染物難以消散,環境保護署十五個監察站中,一度有十三個的空氣質素健康指數錄得「10+」級最高的嚴重水平,污染「爆錶」。

下周初轉涼
天文台表示,「鳳凰」預計會逼近呂宋北部,並進一步增強為強烈熱帶風暴,但按照目前預測路徑,「鳳凰」在本港八百公里警戒範圍邊緣掠過後,會進入南海東北部。天文台預測本港今日雲量較多,有幾陣雨,下周初早上天氣稍涼,氣溫介乎攝氏二十六至三十一度。

受炎熱無風的天氣影響,環保署昨午於葵涌、荃灣、元朗、屯門及塔門等一般監測站錄得空氣質素健康指數為「10+」,其餘兩個在大埔及東區的一般監測站的指數亦達9至10級的甚高水平。受二氧化氮濃度上升影響,銅鑼灣、中環、旺角路邊監測站錄得的空氣質素健康指數亦為「10+」,健康風險級別達嚴重水平,維港一帶蒙上一陣煙霞。

環保署表示,由於充沛的陽光有利光化煙霧現象,令臭氧在區內迅速形成,並在風勢較弱的情況下積聚,致使污染水平上升;市區較微弱的風勢亦不利污染物擴散,令路邊二氧化氮水平較正常為高,預料空氣污染情況在周末仍維持於較高的水平。

How Poor Indoor Air Quality Can Affect your Health

Niagara This Week - St. Catharines http://www.niagarathisweek.com/shopping-story/4766505-how-poor-indoor-air-quality-can-affect-your-health/

Poor Indoor Air Quality (IAQ) is an important health and safety issue.

警惕空氣清新劑3大危害 4招清新空氣

在如今這麼一個不自然的環境裡,空氣裡彌漫著不自然的味道簡直是家常便飯,而作為應對方法,空氣清新劑就變得遍布大街小巷了,但與空調相似,空氣清新劑也有著潛在的不良影響,而且空氣清新劑的不良影響還是會簡單直接粗暴地作用於我們的身體的。

空氣清新劑本質上是由化學物質組成的,它非但絲毫不能吸附、清楚空氣中的污染,還會加重空氣中的污染。而平日裡空氣污染對我們的傷害主要也只是主要體現在化學物質的傷害上,因此,毫無疑問的,空氣清新劑是會加重空氣污染對我們的傷害的,它的作用只是停留在讓空氣聞起來好聞點而已,簡直就是空氣中的味精。

空氣清新劑最明顯的缺陷,是它含有的成分對人體可能帶來的傷害。目前市場上銷售的空氣清新劑種類很多,但基本上都是由乙醚、香精等成分組成,這些物質在空氣中化學分解之後產生的氣體某些成分本身就是空氣污染物,這其實是加劇了車內空氣的污染程度,長期使用對人體會產生不良刺激。
另外,空氣清新劑裡含有的芳香劑對人的神經系統還會產生危害,刺激小孩的呼吸道黏膜等。 空氣清新劑的還有個缺點就是它並沒有分解有害氣體,達到清新空氣的目的。它的作用是通過散發香氣來蓋住異味,而不是與空氣中導致異味的氣體發生反應,也就是說,空氣清新劑的效果並不沒有清除空氣中的有害氣體,它只是靠混淆人的嗅覺來“淡化”異味。

現在,市場上流行的空氣清新劑的成分,大多是由乙醚和芳香類香精等成分組成,這些成分釋放到空氣中後,會分解變質,本身就是一種污染物質。不同的空氣清新劑,只是加入的香精不同,味道不一樣而已,所以應該了解它的危害:

污染環境
空氣清新劑,實際上是掩蓋了異味,並不能從根本上消除異味,所以釋放到空氣中,本身就是一種污染物質,而且他自身分解後,又產生危害物質,而且有的空氣清新劑中,還有一些雜質,也是污染環境的物質。

產生過敏
空氣清新劑中含有的成分,都是有機物,大多會引起過敏,對呼吸道也會產生一些強烈刺激,尤其是對於一些容易過敏的或者是過敏體質的人更是如此。

導致嚴重疾病
空氣清新劑中含有的芳香類物質,可以刺激人的神經系統,影響兒童的生長發育等。歐共體消費者協會,通過調查發現,空氣清新劑甚至可以誘發癌症等疾病。

針對空氣清新劑的諸多弊端,有關專家提出以下幾點使用時的注意事項:

  1. 室內有嬰幼兒、哮喘病人、過敏體質者及過敏性疾病的人時應當慎用。
  2. 噴灑或點燃空氣清新劑時,最好暫時撤離現場,待大部分氣溶膠或顆粒物質沉降後再進入,進入前最好打開門窗通風換氣。
  3. 廁所和浴室的除臭應選用氣體空氣清新劑。
  4. 不能過分依賴空氣清新劑,應從根本上找出惡臭的原因並徹底清除,使居室空氣真正清新。


經過上面的閱讀,大家也知道了空氣清新劑並非一種綠色環保有益的空氣淨化方法,那究竟怎樣的才是正確的空氣淨化方法呢?小編小面就為大家提供幾個:


  1. 自然通風法:不管天氣多麼寒冷,每天均應有一段時間開窗通風,最佳時間為上午9時、下午3時左右,一般要通氣10~30分鐘。
  2. 紫外線照射法:無人時,可在每個房間(15平方米左右)安裝一只30瓦的低臭氧紫外線燈,照射1小時以上,可殺滅室內空氣中90%的病原微生物。
  3. 食醋消毒法:食醋中含有醋酸等多種成分,具有一定的殺菌能力,可用做家庭室內的空氣消毒。每10平方米可用食醋100~150克,加水2倍,放碗內用文火慢蒸30分鐘,煮沸熏蒸時,最好將門窗關閉。每日熏蒸1~2次,連續熏蒸3日。
  4. 艾卷消毒法:還可以在關閉門窗後,點燃艾卷熏,每25平方米用1個艾卷,半小時後,再打開門窗通風換氣。

中國上半年僅九城市空氣質量達標

Air Purifier | http://cn.nytimes.com/china/20140808/c08air/zh-hant/

如果你在尋找一個有潔凈空氣的中國城市,你最好的選擇是深圳、珠海、舟山、湛江、雲浮、北海、海口、三亞和拉薩,據國家環境保護部的統計。

據國家通訊社新華社報道,環保部周三公布,在採用了國家新的空氣質量標準進行環境監測的161個城市中,今年上半年達標的只有上述9個。政府在2012年推出了更嚴格的標準,作為國家對付空氣污染問題的不斷努力的一部分。

中國領導人已經發誓向污染「宣戰」,霧霾作為污染最看得見的形式,經常籠罩着全國各大城市,尤其是在北方。衛生官員警告說,長期暴露在被稱為PM2.5的細顆粒物之中,可導致嚴重的健康問題。去年,給中國被診斷患有肺癌的最年輕患者、一個8歲女孩治病的醫生,把其患病原因歸咎於空氣污染。

空氣質量沒有達到標準的城市包括中國首都北京。這個城市的2000萬居民,包括外來的打工者,也包括政府的領導人,經常暴露在不利健康的高水平PM 2.5和其他污染物之中。

2013年1月,北京市民遭受了一次特別糟糕的空氣污染,黃色空氣中細顆粒物的濃度是世界衛生組織暴露上限指導值的40倍。

北京市政府周一宣布了遏制污染的最新措施。在其官方網站上發佈的聲明中,北京市環保局表示,首都將在2020年底前在六個市區及附近地區全面禁止使用煤炭。其他高污染燃料,如石油焦以及某些生物質燃料也將被禁止。電和天然氣將被推廣為取暖和做飯的能源。

去年九月,中國政府宣布了一項遏制空氣污染的全國性計劃,目標包括降低煤炭占能源消耗總量的比重。一些批評者對這個行動計劃表示失望,因為它沒有對區域的煤炭消耗量設置具體的上限。

世界每年的煤炭消耗大約有一半在中國,燒煤產生諸如細顆粒物等污染物,還產生二氧化碳這樣的溫室氣體。

但是,僅在北京禁止燃煤不會在多大程度上降低中國的煤炭消耗總量,因為北京是「一個非常小的煤炭消耗區,」羅恩·肯德爾(Rohan Kendall)在周四接受電話採訪時說,他是伍德馬肯茲諮詢公司(Wood Mackenzie)的中國諮詢經理。

肯德爾說,「中國的煤炭消耗總量每年超過40億噸,而北京去年僅消耗了1500萬噸煤。」他補充道,北京的大部分能源,以及污染,來自鄰近省份。

他說,他不相信許多其他城市會效仿北京的措施。「煤炭對中國來說太重要了。」

Cleaning the Air

Air Purifiers | home.howstuffworks.com/air-purifier.htm

If ozone generators and ionizing purifiers have questionable efficacy at cleaning air, what can be done to remove contaminants from our homes? There are three basic steps, in order of usefulness:

  1. Get rid of the source of the contaminants. If the problem is cigarette smoke, smoke outside. If mold is causing problems, identify the moldy areas and clean them up. Severe cases may require extensive work to get at mold within walls, but if the mold is left in place, the problem will only get worse. When pet dander is a problem, the pet could be limited to certain areas of the house and kept off furniture. Good hygiene along with regular cleaning and vacuuming will remove a great deal of dust and limit opportunities for mold growth. Using special plastic bags on mattresses and box springs can also keep down allergy-causing contaminants. Image courtesy Andrea Booher/FEMA Mold growing on household walls should be cleaned thoroughly and as soon as possible to avoid illness.
  2. Dilute the air in your house. In other words, open the windows. The air outside probably contains fewer contaminants than what is inside (unless you live downwind from a coal plant). Allowing fresh air inside will sweep away some contaminants.
  3. Clean the air with an effective filter system.

The next logical question, of course, is "how do you know which air cleaners are effective?" Fortunately, there is an industry standard that makes it easy to compare air cleaners. The Association of Home Appliance Manufacturers (AHAM) assigns a Clean Air Delivery Rate (CADR) to air cleaners. AHAM runs a standard test to see how well an air cleaner removes certain contaminants from a volume of air. An air cleaner bearing the AHAM seal will have three CADR numbers listed: one for tobacco smoke, one for pollen and one for dust. A higher number indicates a greater ability to clean air, with maximums of 450 for pollen and smoke and 400 for dust [ref]. AHAM recommends using an air cleaner with a CADR number at least two-thirds the area of the room

From the CADR Web site: "For example, a 10-foot by 12-foot room -- 120 square feet -- would require an air cleaner with a tobacco smoke CADR of at least 80. If your room size is smaller, the unit will simply clean the air more often or faster. If you have ceilings higher than 8 feet, you'll want an air cleaner rated for a larger room."

Air Purifier Criticism



Air Purifiers | home.howstuffworks.com/air-purifier.htm

Ionizing and ozone air purifiers have come under fire from consumer groups, consumer review magazines and even the Environmental Protection Agency (EPA). Two claims are at the heart of the controversy: that these types of air purifiers are not effective at removing contaminants from the air and that ozone generators could harm people.

In 2002 and 2003, Consumer Reports tested several different air purifiers, including Sharper Image's Ionic Breeze. Independent researchers checked and verified the tests. Consumer Reports found that ionizing air purifiers like the Ionic Breeze created "almost no measurable reduction in airborne particles" [source]. Sharper Image sued Consumer Reports. The magazine later conducted further tests in response to Sharper Image's complaints and still found the Ionic Breeze to be ineffective. Sharper Image's lawsuit against Consumer Reports was thrown out, and the company was forced to pay more than half a million dollars to cover Consumer Reports' legal fees.

The EPA has also released information warning the public about air purifiers that generate ozone. Because the manufacturers are not making specific medical claims about these devices, they do not need Food and Drug Administration (FDA) approval. In fact, there really is no government oversight over consumer air purifiers other than the HEPA standard, so any manufacturer claiming that such a device is "government approved" or "government certified" is misleading consumers. However, concerns about the generation of ozone in people's homes have led the EPA to conduct studies on the subject.

All ionizing purifiers generate some ozone, but ozone generators are specifically designed to release the gas, and in much larger quantities than ionizing purifiers. The EPA states, "Relatively low amounts [of ozone] can cause chest pain, coughing, shortness of breath, and, throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections" [source]. Their studies indicated that even when used according to manufacturer instructions, many ozone-generating purifiers created ozone concentrations in a house in excess of public health limits. They also found that ozone as used in a household air purifier "has little potential to remove indoor air contaminants." They also noted that ozone has a tendency to react with chemicals and form by-products that are potentially even more dangerous.

The EPA's final recommendation on the matter: "The public is advised to use proven methods of controlling indoor air pollution." Ozone generators are not among the proven methods listed on its site.

Types of Air Purifiers



Air Purifiers | home.howstuffworks.com/air-purifier.htm

Filters

Some air purifiers clean the air by passing it through a filter that removes particles. These are sometimes called air cleaners. In households, these filters are usually part of the heating or cooling system. A filter housing is installed between the air return duct and the furnace. The filter cartridge slides into this housing, so all air flowing into the furnace is filtered. Not only does this remove contaminants from the air, it prevents damage to the furnace due to dust and dirt build-up. Filters can also be placed into the air return vents in each room of a house. Typical materials include foam, cotton, fiberglass or synthetic fibers. In part, the density of the filter material limits the size of the particles that pass through -- very dense filters have smaller gaps, allowing it to catch very small particles. Pleated filters work best because of the increased surface area for catching particles. However, filters are capable of catching particles even smaller than the smallest gaps in the filter material. Air filters can be expensive, and you have to replace them to keep them functioning properly (some filters are washable). They also restrict air flow through the system, causing a drop in overall efficiency.

HEPA (High Efficiency Particulate Air) filters meet a Department of Energy standard for removing particles from the air. The filter can consist of any material as long as it meets this standard -- penetration of less than 0.03 percent of particles 0.3 micrometers in size or larger [source]. The filter must also allow a specific amount of air to flow through, which varies by the size of the filter. The ULPA (Ultra-Low Penetration Air) standard is even stricter. In addition to their familiar household uses cleaning air of allergens and dust particles, advanced HEPA filters are used by the nuclear power industry.

Ionizing Purifiers

These air purifiers use a method called corona discharge to create charged molecules called ions. Most atoms in the air have a neutral charge -- they have the same number of negatively-charged electrons as positively-charged protons. The corona discharge is a small but intense electrical field. Molecules passing through it will pick up an additional electron, giving the molecule a negative charge, or it may have an electron knocked off of it, giving it a positive charge. Larger particles in the air, such as dust or other contaminants, are more likely to be ionized because they make larger targets for the electrons as they pass through the corona discharge.

Once a particle is charged, it will be attracted to anything with the opposite charge. Two metal plates within the purifier are charged (one negative, one positive) to attract these particles. Also, particles in the air will be drawn to each other if they have opposite charges. As the particles clump together, they get heavier and eventually they settle out of the air.

Ozone Generators

An ozone generator works much like an ionizing purifier, but it is designed to alter molecules of oxygen and turn them into ozone, a molecule made up of three oxygen atoms. Oxygen in the atmosphere exists as dioxygen, a molecule made up of two oxygen atoms. When these molecules are exposed to a corona discharge or UV light, some of the dioxygen molecules split into separate oxygen atoms (free oxygen). While most of this oxygen recombines into dioxygen, some of the atoms form ozone.

Manufacturers of these devices claim that the ozone deodorizes and disinfects the air. Many also claim other health benefits from the presence of ozone. However, there is strong evidence that ozone does not accomplish air purification. Ozone is also known to be a toxic gas. It is not a very stable molecule -- it reacts readily with other chemicals that may be in the air, forming new compounds that can be more dangerous than the ozone itself. Ozone also oxidizes metals and causes corrosion. The same process that creates ozone also creates nitrogen oxides, leading to further reactions with compounds present in the air and with ozone itself.

Adsorbents

Many purifiers incorporate an adsorbent material to take care of odors, fumes and chemicals in the air. Adsorption (not absorption) is the process of one substance being trapped on the surface of another substance. The most common adsorbent is activated charcoal, which is extremely porous and has many microscopic "nooks and crannies" to trap passing molecules. Larger particles are simply stuck in the many pores in the charcoal. Electrostatic attraction draws some substances into the pores. Certain substances react chemically with the charcoal and bond to it. The high surface area of the charcoal gives it lots of bonding places. The process used to make the charcoal can affect which compounds it is better at adsorbing.

UV Light

Ultraviolet radiation renders certain micro-organisms sterile (and harmless). Some air purifiers feature a UV light that bathes the air as it passes through, eliminating the potential harm of airborne bacteria and viruses.

How Air Purifiers Work



Air Purifiers | home.howstuffworks.com/air-purifier.htm

Americans spend an estimated $250 million annually on air purifiers for their homes, with asthma and allergy sufferers responsible for most of the sales [source]. But scientific studies and testing reveal that many purifiers aren't effective at all, and some may be causing harm.

The notion of purifying air has merit, however. The air inside the typical home is generally dirtier than the air outside, because a house can be a source of air contaminants. Moisture can lead to the development of mold and mold spores. Forced-air heating and cooling systems circulate dust particles and bacteria throughout the house. Pets shed fur and give off dander, while smokers pump toxins into the air. Pollen and other outdoor allergens can blow in through open doors and windows (or through a window or door screen) and become caught in carpet or upholstery.

The end result is that the average house tends to concentrate contaminants in greater quantities than the outdoors. This concentration isn't usually too harmful for a healthy person, but children and people with allergies and respiratory difficulties can experience ill effects. Reducing the level of contaminants can help alleviate some of these problems and using an air purifier is one way to do it.

In the next section, we'll look at the five basic types of air purifiers available on the market today.

New study reveals cleaner air could help save lives


A coal power plant 'Scholven' of German utility giant E.ON is pictured in Gelsenkirchen.REUTERS/Ina Fassbender
http://www.foxnews.com/health/2014/07/16/new-study-reveals-cleaner-air-could-help-save-lives/

While some anti-environmentalists claim that clean air standards will cost Americans jobs, a newly published health study shows that clean air standards may have already saved lives.

Published in the June 2014 Journal of Chronic Obstructive Pulmonary Diseases, the study raises the bar for environmental awareness and provides valuable fuel to the cause of clean air. The research team that conducted the study included scientists from Duke University School of Medicine, the Center for Population Health and Aging at Duke University, the Nicholas School of the Environment at Duke and the N.C. Department of Environment and Natural Resources.

In the study, the Duke researchers analyzed deaths in the state of North Carolina due to respiratory disease during a 17-year period between 1993 and 2010, following the implementation of clean air standards. They found a direct correlation between improved air quality in North Carolina since the 1990s and reduced deaths due to pulmonary disease.

Both national and state air quality standards enacted in the early 1990s have helped to provide cleaner air for the most essential of all human physical functions: breathing. The Duke study provides strong evidence that such air quality standards can help save human lives.

One significant factor in North Carolina was the 1992 Southern Appalachian Mountains Initiative, which led to the enactment of the Clean Smokestacks Act to mandate reduced emissions from coal-fired power plants. Some argue that the coal industry is one of the most toxic of all industries in terms of air pollution, and that it can adversely affect water and soil. The coal lobby has steadfastly stonewalled clean air legislation, but this study stands to significantly change the coal argument.

In the study, the Duke team assessed levels of several toxic and potentially lethal pollutants in the atmosphere during the study period, including those known to emit from coal plants.  These pollutants included ozone, sulfur dioxide, nitrogen dioxide, carbon monoxide, and particulate matters. Data was gathered from monthly data measurements from North Carolina air-monitoring stations.

The group looked at North Carolina residents of all ages, and adjusted their data to exclude smokers (who often die from respiratory disease) and those who were known to have specific lung disorders. They calculated deaths in the state due to emphysema, asthma and pneumonia and found steadily decreasing rates of related deaths as air quality improved.

“While a few studies have analyzed the associations of both air quality and health over a long period, they were typically limited to analyses of a specific air pollutant or a couple of pollutants,” said Dr. Kim Lyerly, who headed up the study team. “In contrast, we leveraged access to multiple disparate databases containing either environmental or health data, and we were able to study longitudinally a number of air contaminants, including both particulate matter and noxious gases over almost two decades.”

According to the study, atmospheric reduction of the pollutants, most notably sulfur dioxide, carbon dioxide, and particulate matter, directly correlated with lower rates of respiratory deaths.

Many opponents of clean air standards have claimed that there is little science to back up demands for cleaner air, but this rigorous study, which assesses several pollutants and a broad population, provides exactly that science. And while it should be obvious that we all require clean air for healthy respiration, atmospheric standards have been tough to implement, due to strong lobbying in Congress.

In the battle to provide a cleaner environment, the recent Duke study is a landmark event, and it may point the way to a healthier future.

室內空氣檢測:方法正確數據才可靠

IAQ Air Cleaner | http://www.kaixian.tv/gd/2014/0721/7384948.html

因房屋裝修設計等引起的室內空氣污染危害人體健康越來越受到社會關注,但目前國內市場上室內空氣質量檢測公司卻良莠不齊。專家稱,要獲得真實可靠的室內空氣檢測結果,不僅要選對機構還要選對檢測方法。

  湖南省質檢院總工程師姚斌介紹,目前檢測室內空氣質量 IAQ的依據主要是《室內空氣質量標准》(G B /T 18883-2002)。譬如,檢測甲醛的常用方法主要為“酚試劑分光光度法、乙酰丙酮分光光度法”2種。這些方法都需要將抽取的空氣樣品帶回實驗室進行化學分析來進行檢驗,而不能在現場得出結論。

  同時,取樣的方法還必須正確:比如,小於50平方米的房間應設1個-3個點;50平方米-100平方米設3個-5個點;100平方米以上至少設5個點。抽樣前一定要關閉門窗12個小時。取樣時,取樣器應該距牆至少0.5米的距離,高度為0.5米-1.5米,最好與人的呼吸高度一致。對取樣溫度也有規定,如冬天的室內溫度不能低於16攝氏度、夏天的室內溫度不能高於28攝氏度。如不符合,則要采取升溫或降溫措施。

  但目前市場上,各類“專業”檢測室內空氣質量的企業機構數量眾多,資質技術亦良莠不齊,利用“信息不對稱”欺詐消費者的現像時有發生。姚斌說,為了保護消費者權益,湖南省在今年下半年整頓檢測市場。整頓室內空氣質量檢測市場,對非法、非標進行室內空氣質量檢測或出具虛假室內空氣質量檢測報告的行為進行嚴厲查處。(禹志明)

Air purifiers are not always effective, and some may be harmful


IAQ http://www.scmp.com/lifestyle/health/article/1531695/air-purifiers-are-not-always-effective-and-some-may-be-harmful

Air purifiers are not always effective, and some may be harmful

Air purifiers are not always as effective as advertised, and those that emit ozone may even be harmful, writes Elizabeth Choi

With Hong Kong recording its smoggiest day of the year two Sundays ago, perhaps you were persuaded to not only stay home but also invest in an indoor air purifier.

As the air quality index climbs, so do sales of air purifiers in China. According to Euromonitor International, air purifier volume sales in China rose 87 per cent from 2012 to 2013.

Nowhere in the world is the number of air pollution-related deaths climbing as quickly as it is in Asia, especially Southeast Asia. A 2012 study by the World Health Organisation found that, globally, seven million deaths were attributable to the combined effects of household and ambient air pollution.

Southeast Asian and Western Pacific regions - of which China is part - bear the brunt of those numbers, with 2.8 and 2.3 million deaths respectively.

In Hong Kong, the Hedley Environmental Index, a real-time health information system developed by the University of Hong Kong's school of public health, shows a city map that is often dotted with red during the day, indicating the WHO level of permissible short-term exposure to fine particulates and other pollutants is more regularly "very bad" than it is green ("acceptable"), or even yellow ("not good").

So can a household air purifier protect your health indoors? It's easy to get your hands on one in Hong Kong - at a wide range of prices.

A new, moderately sized model that can purify up to 48 square metres (or about 515 sq ft) can cost more than HK$4,000, while a used machine can cost as little as HK$290 on classified sites such as AsiaXpat.

There are several factors to consider when buying an air purifier, including the volume or space to be cleaned, external weather and environmental conditions of the home, and what types of allergens or pollutants are being removed.

"There are many types of air purifiers - some of them sterilise air or use ultraviolet or other heating systems to kill germs," says Dr Fanny Ko Wai-san, a specialist in respiratory medicine and president of the Hong Kong Thoracic Society.

While purifiers with special heating systems may be sufficient for killing germs, they may not be adequate in removing fine or respirable particulates that can exacerbate allergies or asthma.

That's not including toxic gases such as nitrogen dioxide, which comes from gas-burning stovetops, or sulphur dioxide, emitted from cars and ships.

Despite becoming increasingly popular, home air purifiers aren't essential for the average household in Hong Kong, Ko says.

"Most people live without one, and without any problem," she says. "It will not lead to a cure for allergies or asthma. Some patients in previous studies show they have the air purifier, but don't show any signs of improvement. You can install one and find it provides no benefits."

A number of variables determine an air purifier's effectiveness.

"Sometimes, indoors can be very moist and, in those situations, an air purifier can be helpful," Ko says. "But if you open the windows, there's almost no point because the pollution comes in. Can it really help or translate into improvement? It's hard to say."

Ko says air purifiers could be considered for places such as hospitals that need to prevent infection, or work settings in industrial areas with extreme levels of particulate matter.

"In general, however, we do not recommend installing air purifiers unless the asthma is difficult to control. In the end, it's a personal preference over a scientific reason," she says.

Their use might be justified for those with acute allergies or asthma. But even in those cases, most specialists prescribe medicine as a treatment.

Studies and tests show mixed results of how well these machines can purify indoor air from toxins, germs and particulate matter.

Indoor air purifiers are advertised as safe household products for health-conscious people, but some purifiers produce ozone. Those that work by charging airborne particles and electrostatically attracting them to metal electrodes emit ozone as a by-product of ionisation.

Emissions may be a few milligrams of ozone an hour, about as much as a dry-process photocopier emits during continuous operation. In a small, poorly ventilated room, this could create an ozone level that exceeds public health standards, according to a study by the University of California, Irvine, published in 2006 in the Journal of the Air & Waste Management Association.

Ozone can damage the lungs, causing chest pain, coughing, shortness of breath and throat irritation. It can exacerbate chronic respiratory conditions such as asthma and compromise the body's ability to fight respiratory infections.

In 2011, the Hong Kong Consumer Council tested 10 air purifiers priced from HK$629 to HK$4,000, and found that they all provided a less usable area of purified air than they claimed. In seven of the larger models, the shortfall ranged from 12 per cent to 67 per cent. In the three small models, the shortfall was up to 90 per cent.

The study also found the four models provided insufficient protection from electrical leakage, while the plastic parts of some models were insufficiently heat and flame retardant.

Ko says many household cleaning supplies, office equipment such as copying machines, pesticides and painting materials can contain and emit harmful volatile organic compounds (VOCs) that can have short- and long-term effects that range from eye, nose or throat irritation to asthma, and may even cause some cancers.

According to the US Environmental Protection Agency, all of these products can release organic compounds while being used, and to some degree, when they are stored.

"Choose furniture that doesn't have VOCs," Ko says. "Those may be the source of emissions in the home, but an air purifier may not be tackling the source. Clean your carpets, too as they can produce allergens and house a lot of dust.

"A dehumidifier is a home essential. It can help with preventing moisture and mould in the home," Ko says.

空調成夏季室內污染重災區 散熱片細菌是馬桶60倍



IAQ : http://www.ldnews.cn/property/jiazhuangzixun/201407/315258.shtml

夏季的高溫使得空調使用變得頻繁,然而消費者所不知的是,往往夏季的室內污染就是由此開始。據最新實驗數據顯示,在空調長期不使用或者不定期清理的情況下,空調散熱片細菌含量是同樣單位面積下馬桶細菌總數的60余倍。有關專家建議,除經常通風外,定期對空調散熱片和濾網進行清洗已是當務之急。

空調散熱片危害大
數據顯示,消費者平均85%以上的時間是在室內度過的,而夏季,在室內學習和工作的時間甚至達到90%以上。然而往往室內的空氣污染情況要更甚室外,其根源就是家用空調。

日前中國環境科學學會室內環境與健康分會聯合上海家化家安品牌進行了室內空氣測試活動,結果顯示,空調散熱片的“毒性”要大於馬桶,如果消費者忽視空調產品的日常清理問題,室內的空氣環境將更加糟糕。

此前,復旦大學做了一場實驗,對使用分體掛壁式空調的30戶居民住宅做了入戶調研,分別在空調散熱片、馬桶內壁和抹布上取樣,並將收集好的樣本放入培養皿中進行細菌培養並計數,檢測室內分體掛壁式空調散熱片、馬桶和抹布的微生物污染狀況。在此次檢測中,空調散熱片的細菌含量每平方釐米最高可達1200cfu,是馬桶細菌總數的60余倍;而空調散熱片的霉菌總數則高達每平方釐米960cfu,是馬桶的近30倍。

易滋生多種細菌
據中國環境科學學會室內環境與健康分會名譽理事長田德祥介紹,空調污染是夏季室內空氣污染的主要因素,而空調散熱片是空調污染的罪魁禍首。原因在於空調散熱片是冷熱空氣交換的必經之地,冷凝水在這裡產生,長期處於潮濕環境,細菌在此大量滋生。

清華大學建築學院教授張寅平表示,現實生活中細菌是普遍存在的,這是不可避免的,細菌往往依附在空氣中的微顆粒物上,隨空調流動而流動。而空調散熱片正處於空氣流動途經,空氣中的細菌容易在此堆積。另外,空調散熱片附近的溫度和濕度相對而言也較為適合細菌生長。

據一項來自新加坡的研究數據表明,有空調的室內空氣細菌濃度高於無空調的房間。復旦大學調查結果也顯示,有近9成的家庭空調散熱片細菌超標,有的家庭甚至超標1000倍。另外,復旦大學的檢測證實,大多數家庭的空調積塵中細菌、霉菌超標,最嚴重的家庭空調細菌數量超過商場中央空調50倍。

用戶需定期殺菌消毒
業內專家建議,空調用戶可以從換氣、源頭等方面來改善室內空氣質量。張寅平表示,使用空調設備的室內環境相對封閉,空調基本在室內循環,這樣容易導致室內空氣微生物積增無法排出。因此當空調連續使用一定時間後,要開窗通風。

另外,定時清洗和消毒也同樣重要,可以從源頭上進行消毒殺菌。參與此前聯合調查的上海家化家安工程師也建議消費者,當家中空調長時間閑置後,開機前最好能夠清洗消毒一下過濾網和散熱片,這樣能夠有效避免各種細菌進入室內。

空調散熱片因為不可拆卸,僅靠濕布擦拭、刷子清潔等手段是沒有用的,而且還容易損壞散熱片,可以用專用的洗滌劑清洗。對於空調消毒劑品牌的選 擇,業內專家建議選用有權威機構認證對人體和機器安全的、殺菌效果顯著、具有衛生部門“消”字證號的產品。條件允許的話,盡量每個月消毒一次過濾網和散熱片。(編輯/鄧仕姣)

消委會:空氣清新機誇大功能



(星島日報報道) http://std.stheadline.com/archive/fullstory.asp?andor=or&year1=2005&month1=4&day1=16&year2=2005&month2=4&day2=16&category=all&id=20050416a10&keyword1=&keyword2=

空氣污染指數屢創新高,故近年不少家庭都會購買空氣清新機。但消委會的測試顯示,所有空氣清新機有誇大其淨化面積之嫌,有型號聲稱可淨化四百多呎家居,但結果僅為三十呎﹔而消委會又對清新機可殺菌、除病毒的功能存疑。

消委會聯同機電工程署,測試市面十款、售價介乎一千至三千元不等的空氣清新機,測試其淨化效能、寧靜程度、方便性及安全程度。結果發現,以五分為滿分,整體表現介乎三分至四分半之間。各型號的淨化效能十分參差,最低評級僅得二分,最高則為四分。

值得注意的是,所有空氣清新機均有誇大其可使用面積之嫌,其中一款聲稱最大的可使用範圍達四百三十方呎,但消委會的測試結果,僅得三十二方呎,連聲稱的十分之一範圍也不及。

不過,消委會宣傳及社區關係小組副主席程伯中亦指出,在計淨化面積時,現時國際上沒有統一的計算標準,因此,生廠商的計算方法和條件或有不同,兩者數字未必可直接比較。

他指出,不少清新機均聲稱可以除菌、除病毒,但他質疑空氣清新機殺菌及消滅病毒的功效。因為根據專家意見,最有效的方法是找出及控制污染源頭,注意家居生及其他預防疾病措施,不宜單靠空氣淨化機來清除空氣雜質。

在安全性方面,十款測試樣本中,僅得三款完全通過最新版本的IEC國際標準,其餘樣本未如理想的地方,包括部分物料的耐熱或防火程度未符合新規定、絕緣距離不足、帶電部分或基本絕緣可被觸及。

程伯中表示,早期國際間有一套較寬鬆的舊標準,但近年則有一套較嚴緊的要求,不少產品仍沿用過往的生產標準,由舊制過渡至新標準有一段過渡期,故有關產品沒有違規。

消委會並指出,聲稱會產生負離子的空氣清新機,表面上不比純粹用隔塵網的樣本優勝,而結果亦顯示,樣本效能受送風量影響,通常送風量愈高,除塵的速度亦愈高。

空氣污染指數破100點‧煙霾重臨芙波“失守”


(森美蘭‧芙蓉23日訊)煙霾重臨;芙蓉和波德申的空氣污染指數今午先後失守,突破100點的不健康水平,市民受促展開“抗霾”行動。

芙蓉市區的街景在煙霾的襲擊下,顯得朦朧。(圖:星洲日報)

在風向影響下,森州的芙蓉與波德申等地上空過去幾天來皆迷濛一片,遠景被煙霾遮蓋,空氣還出現少許的燒焦味,景色能見度低,令人感到鬱悶。

近來多日沒有下雨,加上猛烈的太陽,已令人感到不適,再加上這幾天的煙霾問題,讓人只想待在冷氣房內,不願意外出。

空氣充斥著燒焦味
根據大馬環境局的空氣污染指數(API),截至今日下午5時,芙蓉的空氣污染指數從上午的75點飆升至下午的107點,空氣還充斥著燒焦味。

另一方面,波德申的情況也於芙蓉不相上下,污染指數從上午的86點飆升至下午的101點,而汝來的煙霾情況則較輕微,指數是85點。

芙蓉上午的空氣污染指數屬於健康的水平,突然於下午轉壞,還突破100點的不健康水平,相信是與風向有關。

IAQ: How Do You Stack Up When It Comes to Indoor Air Quality?

http://www.triplepundit.com/2014/06/indoor-air-quality/

When most people think of sustainability, they think of things like renewable power, energy and water conservation, or recycling. But sustainability is all about recognizing the interconnectedness of things. That means taking care of the things that take care of the things that take care of us: like our air. And though we often think of the environment as what’s outdoors, there is also an environment indoors, and we need to take care of that, too.

Why should we care about indoor air quality (IAQ)?

Well, the first reason is our health. Consider the following facts: First of all, most people spend roughly 90 percent of their time indoors these days.

Secondly, indoor air pollution is two to five times higher than what is generally found outdoors. With help from the American Lung Association of Minnesota, here is a list of pollutants that can often be found lurking within our indoor air. These generally fall into several categories including:

  • Products of combustion (e.g. ash, soot, carbon monoxide, polycyclic aromatic compounds)
  • Biological agents such as molds, pet dander, and pollen
  • Volatile organic compounds
  • Metal dust such as mercury or lead
  • Radioactive particles such as radon, and
  • Asbestos
  • Cooking effluents including nanoparticles
  • Ozone

The Environmental Protection Agency lists poor indoor air quality as the fourth largest environmental threat to our country. Quite often the health impacts of poor indoor air show up as allergies and asthma. There are an estimated 40 million individuals in the United States who are affected by allergies, and the prevalence rate of pediatric asthma has increased by 72.3 percent. Asthma is now the sixth ranking chronic condition in our nation and the leading serious chronic illness of children in the U.S.

Poor indoor air quality can also be detrimental to the long-term health of buildings and structures, primarily due to excessive moisture and mold which can accumulate and weaken structural materials.

Recent studies have found that indoor air quality can have a significant impact on workplace productivity as well.

Sources of indoor pollution include combustion processes, such as cooking, fireplaces and furnaces in the home, or any number of manufacturing processes in the workplace, even printers and copiers. A second source, which has received a great deal of attention lately, is that of synthetic materials ranging from paint and carpeting to industrial adhesives, cleaning supplies, plastics, furniture finishes and numerous other things that all have been found to emit a class of indoor pollutants known as volatile organic compounds (VOC). VOCs are chemicals that off-gas easily from products and mix with the indoor air that building inhabitants breathe in thousands of times a day. According to UL Environment, the vast majority of these compounds, as much as 96 percent, are introduced in the construction of buildings.

That is why so much attention is now being given, through programs like LEED and GREENGUARD, to certify those materials being used in buildings, so as to minimize or eliminate VOC exposure from these sources.

According to the American Lung Association, the primary line of defense against indoor air pollution is prevention. Keeping those materials that emit dangerous VOCs out of the building in the first place is the simplest and most effective way to deal with the problem. If it’s too late for that, if the building is completed and can’t be remediated, the next best thing is adequate ventilation. That assumes that bringing in outdoor air will improve air quality, which is generally, though not always, true — since, in some cases, the outdoor air could be even more polluted depending on location.

Finally, air cleaners or purifiers — which circulate air through filters that can remove some of the contaminants — can also be helpful, though as Ben Franklin famously said, “An ounce of prevention is worth a pound of cure.”

空氣質素健康指數

http://www.gov.hk/tc/residents/environment/air/aqhi.htm

環境保護署公布的空氣質素健康指數告知市民在本港由空氣污染引發的短期健康風險,以便市民能採取預防措施,保障健康。本文將介紹空氣質素健康指數怎樣運作與及由空氣污染引發的短期健康風險的資料和訊息。

如何計算及公布空氣質素健康指數?

每小時的空氣質素健康指數是將環境保護署每個空氣質素監測站所錄得的四種主要空氣污染物,包括臭氧、二氧化氮、二氧化硫和粒子(包括可吸入懸浮粒子及微細懸浮粒子,選其影響較大者)估算會導致的入院風險增幅相加而得。指數以三小時移動平均污染物濃度為計算基礎,而每種污染物的風險系數均來自本地的健康研究。空氣質素健康指數以1至10級及10+級通報,並分為五個健康風險級別。

環境保護署會每小時計算及公布每個一般和路邊監測站的空氣質素健康指數,讓市民可即時知道最新的健康風險情況,同時亦會提供空氣質素健康指數的預測,以便在因空氣污染出現高健康風險級別前向你作出預警。

我們可從空氣質素健康指數中知道怎麼?

空氣質素健康指數估算因空氣污染導致呼吸系統及心血管疾病而入院的額外短期健康風險。指數參考了世界衞生組織的短期空氣質素指引,並根據該指引界定因短期接觸空氣污染而引起高健康風險的空氣質素水平。空氣質素健康指數以1至10級及10+級通報,分為以下五個健康風險級別並提供健康忠告。

當健康風險級別在低至中水平,市民可以如常活動;當健康風險級別達到高水平,兒童、長者和患有心肺疾病的人應減少戶外體力消耗;若健康風險級別達到甚高或嚴重時,一般市民亦應減少或避免戶外體力消耗。請參考環保署健康忠告內更詳盡的建議。

When purchasing an Indoor Air Quality Test Kit, be sure that the test kit will detect the allergen, or contaminant that you are testing for (All test kits are not created equal!). Also, make certain that the test kit purchased will test the home in it’s entirety (usually based on square footage). It is important to know that indoor air quality test kits are not recommended for all purposes, and that adverse health, and environmental conditions can demand a professional consultation.

Variations Between Test Kits

Indoor Air Quality Test Kits can range in price from $50 – $1,600 depending on the number of contaminants, tested for, and the breadth of testing that is performed. Some test kits can be performed at home, and some require the results be mailed to an test lab for further analysis. Turnaround time for the test kits will be dependent on the type of testing, the test kit, and the test lab; some tests may yield results within hours, while some may take weeks for a complete assessment report.

EPA’s Methods for Testing

(Excerpt from “Indoor Air Quality Solutions and Strategies” by Steve M. Hays)2

EPA’s compendium of methods for indoor air. In response to the need for specific guidance on the determination of indoor air contaminants, EPA has developed testing methods for the determination of selected contaminants in indoor air. However, EPA cautions that these testing methods at this time are not certified and are not officially recommended or endorsed by the EPA. The following testing methods have been developed:

  1. Volatile organic compounds using SUMMA® stainless steel canister sampling or solid adsorbents.
  2. Nicotine using XAD-4 solid adsorbent, active filter cassettes, or passive filter cassettes.
  3. Carbon Monoxide and carbon dioxide using nondispersive infrared spectroscopy or gas filter correlation.
  4. Nitrogen dioxide using continuous luminox LMA-3, Palmes diffusion tube, passive sampler badge, or a transducer technology electrochemical technique.
  5. Formaldehyde using solid adsorbent Sep-Pak 2,4-DNPH cartridge, passive sampler badge or a continuous CEA monitor
  6. Benso(a)pyrene and other polynuclear aromatic hydrocarbons in air using a combination quartz filter/adsorbent cartridge with subsequent analysis by gas chromatography with flame ionization and mass spectrometry detection or high-performance liquid chromatography
  7. Selective pesticides using low-volume polyurethane foam sampling with gas chromatography/electron capture detector.
  8. Acid, bases, aerosols, and particulate matter using an annular denuder coupled with filter pack assembly or transition flow reactor
  9. Particulate matter using an impactor with filter pack assembly or a continuous particulate monitor
  10. Air exchange rate using a perfluorocarbon tracer or tracer gas.

室內空氣差 林口長庚CO2超標 濃度逾標準1300ppm



〔記者邱奕統/桃園報導〕 http://news.ltn.com.tw/news/life/paper/787781

桃園縣環保局去年底對縣內醫療院所、幼兒園、桃園國際機場航廈、安養院與百貨公司等一四五處公共場所巡檢室內空氣質素,結果十一處二氧化碳濃度超標,經複檢僅林口長庚醫院仍未改善,最高達二三○○ppm,超出標準值達一三○○ppm;長庚醫院表示,已持續改善空調設備。

長庚︰持續改善空調設備
環保署制定「室內空氣品質管理法」,自一○一年開始實施,今年元月將醫療院所、安養院、政府機關、車站、捷運站、百貨公司、大賣場等列為首波列管公告場所,七月起開始管制室內二氧化碳濃度等空氣污染物標準,一○五年起若不符標準,更需在出入口標示「室內空氣品質不合格」,還可處五萬至廿五萬元罰款,情節重大更可停止營業。

二氧化碳因與部份空氣污染物含量成正比,可做為室內空氣質素 IAQ標準,依環保署公告的「室內空氣品質管理法」,標準值應為一○○○ppm以下。環保局空氣品質保護科長蘇振昇說,去年底巡檢縣內各公共場所,各項污染物僅發現二氧化碳濃度超標,長庚醫院原有醫學、病理、復健、兒童等四個大樓超標,到目前仍有病理、復健、兒童三處大樓還未改善,仍在一○○○ppm以上。

建議定時換氣、增設空調設備、改善管線配置增加空氣流通。
壢新醫院家庭醫學科主任陳聲平說,吸入過量二氧化碳就如同服下過量的鎮靜劑,會造成呼吸趨緩甚至中止,引起二氧化碳中毒,嚴重恐死亡,二氧化碳濃度若超過八○○ppm,多數人會感到疲倦、頭痛、精神不振、注意力不集中、打呵欠等情形,若超過一○○○ppm,更會影響呼吸與大腦機能。民眾若在室內感到昏沉等症狀,就應外出透氣,開窗引進新鮮空氣、擺放綠色植栽都有助降低二氧化碳濃度。

空氣清新機PM2.5甲醛淨化率99%純屬吹牛

http://health.takungpao.com.hk/q/2013/0522/1626252.html

「PM2.5去除率99.99%」、「甲醛淨化率99%」、「現場除菌性能99%」……在空氣清新機的機身上,消費者常常會看到這些醒目的標識。對於空氣環境質量的擔憂,對於PM2.5和甲醛的敏感反應,讓眾多消費者願意掏錢買一台空氣清新機。

但是這些指標真的靠譜嗎?昨天,市消保委向社會通報了空氣清新機比較試驗結果,號稱甲醛淨化率99%的夏普空氣清新機實測值僅為61%,三星的實測值為50%,而樂扣樂扣的實測值僅為8%,「淨化」水平讓人堪憂。更有專家爆料,甲醛淨化率、PM2.5去除率等消費者關注的指標都是廠商按消費者偏好而設計出來的描述指標,根本沒有相應的衡量標準。

連營業員也說不清指標

霧霾天氣的多發,讓市民越來越重視空氣質量問題,正是看中了這一點,各廠家紛紛推出了空氣清新機產品。根據記者的初步統計,市場上目前在售的空氣清新機品種在700種以上,幾乎包括了所有知名3C廠商。

昨天下午,記者來到國美電器徐家匯二店,這裏展示着20多款空氣清新機,記者看到,不少品牌的機身上,貼滿了功效水平。萊克的一款售價3000元的「智淨星」產品上,貼着「殺菌99.5%、淨味98.0%、除甲醛98.5%、去PM2.5率99.9%」,讓人感覺「十項全能」,二樓的夏普「淨離子群空氣消毒機」,宣傳單上甲醛祛除率、現場除菌性能、PM2.5去除率均達到99%。不少淨化器為突出功能,甚至增添了甲苯效率、有機化合物去除率等。不過當記者詢問各項指標的明確含義時,營業員對於「有機化合物去除率」等不少功能表示「自己也搞不懂」。

不過記者從各大商家處了解到,無論是線上線下,空氣清新機都是今年3C類最暢銷的產品。蘇寧、永樂今年以來空氣清新機的銷量普漲37%至70%,許多品牌型號幾度脫銷。而易迅網的統計數據顯示,今年1-4月共售出各種空氣清新機超過26000台。

甲醛淨化效率最低才8%

消費者購買的空氣清新機,真的如廠家宣傳那般「一機在手,空氣質量無憂」嗎?昨天市消保委發布通告,對於22台價格從1488元至9300元不等的各品牌中高端型號抽檢結果顯示,空氣清新機的質量令人擔憂。

據消保委透露,問題最大的指標為甲醛淨化效率。測試結果表明,22台樣品中,只有2台樣品的淨化效率達到了97%。高價位的夏普空氣清新機(KJF420AA)甲醛淨化效率僅為61%、大金(MC70KMV2-R)的實測值僅為56%、三星(AC-347HPAWQ)與格力(KJG155A)的實測值都僅為50%。更有8台樣品的淨化效率在20%以下,包括伊萊克斯、LG、福瑪特等知名品牌,樂扣樂扣(ELA-230C)的甲醛淨化效率僅為8%,連個零頭都不到。8%是什麼概念,市環檢站實驗室主任、高級工程師沈浩給記者舉了個例子,只要開窗通風,甲醛淨化率都能達到50%。

此次檢測的其他三項主要指標包括PM2.5淨化效率、能效等級和潔淨空氣量。報告指出,所有樣品的PM2.5淨化效率普遍在78%以上,但真正達到宣傳所稱「大於99%」的只有兩台。而在潔淨空氣量的抽檢中,有6台與明示標稱要求不符,8台沒有標注潔淨空氣量。如萊克(KJ701-3)的實測值僅為明示值的57%,但企業對此辯稱,這是由於未開啟離子殺菌功能造成的。

據悉,所有涉嫌性能不合格及虛假宣傳的空氣清新機,市消保委已經移交相關部門進行處理。

兩大主要指標“無中生有”

購買空氣清新機,大部分消費者最關注的兩個指標是“PM2.5淨化效率”以及“甲醛淨化效率”。但在采訪中,市消保委、市環檢所相關負責人均明確表示,這兩個指標主要靠企業自身的描述來展現,是企業根據消費者的偏好而設計出來的,根本找不到對應的相關標准,缺少權威性。

沈浩解釋說,我國出台的國內空氣清新機的標准有6項,其中強制性標准有2項,分別是對空氣清新機的安全性、臭氧濃度以及抗菌除菌、淨化功能而設的強制標准。上海在去年12月出台了更嚴格的上海地方標准(DB31/662-2012),在能效等級上提出了高標准;此外,行業內還有一些潔淨空氣量和適用面積等方面的推薦性標准。但無論哪個標准裡,都找不到PM2.5淨化效率和甲醛淨化效率兩項指標。“事實上,這兩個指標都可以用潔淨空氣量和適用面積的指標來闡述,即類似於空調制冷量的衡量標准,但企業卻選擇更容易被市場接受的形式來規避量化標准,無中生有創造了這兩個效率。”

市消保委常務副秘書長陶愛蓮評價指出,目前空氣清新機行業主要有“三亂”。一是宣傳混亂,企業過分誇大產品功效,幾乎所有產品都標注了99%的淨化率,甚至還有企業展示了淨化檢測報告,讓消費者難以選擇。二是認證混亂,標准缺失,認證靠企業自身描述,出台的6項標准沒真正起到行業規範作用。三是價格混亂,市場上的零售價格從千元至萬元皆有,讓人摸不著頭腦。市消保委表示,空氣清新機是一個快速發展的行業,需要進一步加強規範與自律。除此之外,有關部門也應進一步完善國家標准並落實執行,以規範空氣清新機市場秩序,保障消費者合法權益。

車載空氣清新機真心不靠譜

http://jd.zol.com.cn/458/4580303.html

車載空氣清新機的淨化原理
國務院新聞辦4日上午發布《2013中國環境狀況公報》。公報顯示,2013年,按照空氣質量新標准實施監測的74個城市中,僅海口、舟山和拉薩空氣質量達標。中國空氣污染問題依舊持續。空氣污染對人體危害有多嚴重?中國解放軍306醫院呼吸道疾病教授王萍女士告訴記者,室外空氣污染將增加40%的缺血性心髒病,40%的腦卒中,11%的慢性肺病以及6%的肺癌。空氣雖然看不見,摸不到,但空氣污染已經嚴重影響了人類健康。

嚴重的空氣污染加速了空氣清新機類產品的銷量,這其中就包括車載空氣淨化類產品。但是作為媒體,我們必須要質問,車載空氣清新機真的有用嗎?

別花冤枉錢 車載空氣清新機真心不靠譜

 

車載空氣清新機的淨化原理

負離子淨化技術:

使用負離子淨化器技術的車載空氣清新機代表主要是三星(三星稱Plasmaion)和夏普(夏普稱淨離子群),這類空氣清新機外觀上多采用杯狀設計,可以放在車內水架上。產品主要通過負離子發生器,向空氣中釋放負電荷,通過負電荷與水分子、顆粒物的結合讓顆粒物進行主動的沉降與吸附作用降低PM2.5。

車載空氣清新機究竟有沒有用?
目前廠家宣傳的負離子淨化器通常宣稱以“主動式”的淨化,在淨化器運行過程中無需物理式的攔截即可實現PM2.5的降低。此外,局部區域高濃度的負離子易產生臭氧O3或者氫氧基,借助強氧化作用破壞細菌表面,實現殺菌的目的。

負離子淨化技術並不能算真正的PM2.5技術,主要原因是它的淨化效率太低(CADR潔淨空氣),很難在短時間內實現高效的空氣淨化空氣。也正因如此,家用型空調產品上沒有采用負離子單一功能的空氣清新機產品。這類產品也難以通過美國AHAM的CADR的測試認證

HEPA過濾技術:

HEPA濾網淨化技術是目前最為成熟的顆粒物淨化技術,對家用型空氣器了解的用戶對該技術並不會陌生。符合HEPA標准的過濾器的用途很廣泛,從醫療設備、汽車(下面會告訴大家用在什麼地方)、飛機及家居均可應用。濾網的標准由美國能源部設定,對粒徑在0.3μm的粒子, 過濾效果約為DOP 99.97%以上。通常使用的高效濾網可達到99.99%的攔截效率。

車載空氣清新機究竟有沒有用?
HEPA濾網的攔截機制

HEPA過濾網包括四種過濾機制。

  1. 第一種即為攔截機制,對大顆粒物起作用。
  2. 第二種機制為重力影響,體積小密度高的顆粒,在經過HEPA濾網時運動速度會降低,自然沉降到HEPA上,此過程有點類似水中泥沙在河下游沉降的過程。
  3. HEPA濾網的第三種機制為,氣流影響。由於HEPA濾網編織不均勻,形成大量的空氣漩渦,超小顆粒物受到此氣旋的影響吸附在HEPA濾網上,實現過濾目的。
  4. 第四種過濾機制為超微顆粒在布朗運動的作用下撞擊到HEPA濾網纖維上受到範德華力影響,被過濾。

HEPA的優勢是技術成熟,同時由於采用物理過濾方式,不會形成二次污染。缺點則是HEPA風阻較大,對風機要求較高,越高級的HEPA濾網,風阻值越大。另一個問題則是用戶更為關注的維護成本,由於北京等地的空氣質量遠低於歐美國家,HEPA濾網的使用壽命僅能維持在半年左右,更換費用昂貴,此外國內沒有相應的回收機制,對環境造成污染。

車載空氣清新機受限因素是哪些?

車載空氣清新機受限因素是哪些?

在原理上,由於車載空氣清新機與室內空氣清新機采用了同樣的HEPA濾網,在理論上可以實現對PM2.5的淨化。但由於車內的實際情況,車載空氣清新機的淨化效果將受到局限。主要包括的受限因素有兩個。

一:功耗、噪音、尺寸限制了大功率風機

首先是電力供應問題,空氣清新機的核心部分包括兩個部分第一個是濾網,決定了單次淨化效率;第二個部分是風機,足夠大的風量可以在同樣的時間內循環更多的空氣。這也就是我們說的單位時間內輸出潔淨空氣量的概念。

車載空氣清新機究竟有沒有用?
受到多重因素限制,車載空氣清新機難以提供大功率風機

我們都知道,所有汽車供電都通過點煙器接口,雖然有部分車輛提供了220V電壓接口,但為了提高產品的通用性,目前車載空氣清新機均采用12V點煙器接口。這就出現了一個問題,由於功率的限制,車內空氣清新機就不能將大功率風機。此外,車內對空氣清新機的運行噪音、機身尺寸都有更為苛刻的限制,車載空氣難以配備大馬力風機。在我們的實際測試過程中也發現,車載空氣清新機普遍存在出風口風速低、風量小的問題。這與汽車本身自帶的空調出風相比,差異明顯。

二:車內環境復雜,低風速易形成淨化死角

車載空氣清新機究竟有沒有用?
前排座椅形成了空氣循環屏障

第二個問題是車內環境的問題,以標准型5座汽車為標准,由於車內前排座椅的遮擋,形成天然屏障,加之車載空氣清新機出風口風速不足的問題,導致放在前排的車載空氣清新機形成小區域循環,車內空氣僅能通過空氣濃度的自然平衡進行過濾,而整個過程是被動的。

不買車載空氣清新機一樣去除PM2.5

不花冤枉錢 沒車載空氣清新機一樣去除PM2.5

看到這個標題,相信很多用戶都會質疑,不用空氣清新機,PM2.5顆粒一樣可以去除?在了解車載空氣清新機的淨化原理後我們知道,空氣淨化的核心關鍵在於濾網,而汽車恰恰給我們提供了這樣的濾網——車載空調濾芯就是一個標准HEPA濾網(部分車型沒有)。這意味著只需開啟空調(通風),我們即可實現對PM2.5顆粒物的有效淨化。

車載空氣清新機究竟有沒有用?
車載空調濾芯就是一個標准的HEPA濾網

口說無憑,我們用數據說話。5月31日,我的同事撰寫了《效果真心不明顯 8款車載空氣清新機橫評》一文,在文章中,他對車載空調淨化能力進行了測試,原文:“在最大風量下,即使將檢測儀器放置到距離出風口較遠位置,比如扶手箱上,車載空調自帶的濾網淨化能力要遠勝於所有此次被測試的車載空氣清新機,對比結果非常直觀。當車輛外界空氣質量良好,開啟空調外循環之後能夠進一步淨化車內空氣。所以,相比車載空氣清新機而言,車輛自帶的空調和空調濾網的淨化能力在較大風量下,依舊是最簡單、高效的淨化方式。”

車載空氣清新機究竟有沒有用?
開啟空調內循環即可有效降低車內PM2.5數量

當然,利用車內空調對PM2.5進行淨化還需要合理的設定。我的同事針對內循環和外循環對車載空調的淨化效果進行了對比測試,測試數據如下,從數據中我們可以明顯看到,內循環模式下的淨化效果遠高於外循環模式。因此,在實際使用過程中,我們建議用戶常開啟車載空調的內循環模式,以提高對顆粒物的淨化效果。

原車空調淨化能力測試(測試時間各1分鐘)

原車空調(內循環)
原車空調(外循環)
淨化前PM2.5濃度
52406
45212
淨化後PM2.5濃度
45212
31088
淨化前PM10濃度
3550
3698
淨化後PM10濃度
3698
3423
淨化PM2.5能力
7194
14124
淨化PM10能力
148
275

空氣淨化的核心材料是濾網,由於不同車輛所使用的空調濾網材質的差別,因此實際淨化效果也會存在明顯區別。目前在更換空調濾芯時,有第三方濾芯可供選購,建議用戶在選購時盡量選擇知名品牌的空調濾芯,以提高車載空調的淨化效果。

結語:

相信看到這裡,用戶心中都有了答案。雖然空氣清新機可以實現對PM2.5顆粒物的淨化,但受限於尺寸、供電等多方問題,車載空氣清新機難以拿到最佳的淨化效果。對比之下,搭配HEPA空調濾芯的車型,在開啟空調內循環後即可有效的淨化車內空氣,在這種情況下車載空氣清新機已無購買意義。

前面的內容我們更多的說了,車載空氣清新機對PM2.5的淨化效果。由於車內污染還包括甲醛、苯有害化學物質;微生物、病毒等生物污染,車內需要定期進行專業臭氧消毒,以實現最佳的車內空氣狀態。

 

雖然空氣清新機可以實現對PM2.5顆粒物的淨化,但受限於尺寸、供電等多方問題,車載空氣清新機難以拿到最佳的淨化效果。對比之下,搭配HEPA空調濾芯的車型,在開啟空調內循環後即可有效的淨化車內空氣,在這種情況下車載空氣清新機已無購買意義。
