PM2.5口罩熱銷作用有限

PM2.5 masks become popular?

A type of anti-PM2.5 face mask is selling like hot cakes on the Internet, as China has been covered by dense fog and air pollution for several days, eastday.com reported.

據(jù)東方網(wǎng)報(bào)道，連日來，受霧霾和空氣污染的影響，一類"PM2.5口罩"在網(wǎng)絡(luò)的銷售火爆起來。

Nearly 1,500 entries for so-called PM2.5 masks can be found on Taobao, with prices ranging from RMB1-100. Most of these products claim to be antibacterial and dustproof, with activated carbon fabric and even antitoxins.

在淘寶網(wǎng)可查詢到近1500條相關(guān)產(chǎn)品的信息，價(jià)格從1元到100元不等。產(chǎn)品宣傳中多以抗菌、防塵、添加活性炭、甚至防毒為賣點(diǎn)。

But experts warn that most of these products can do nothing to prevent inhalation of tiny particulate matter less than 2.5 micrometers in size, suggesting reduction of outdoor activities can be far more effective.

但專家稱，市面上大多數(shù)所謂PM2.5口罩根本無法阻隔PM2.5微粒，對于pm2.5防護(hù)，建議市民還是以減少戶外活動為主。
