Shanghai to pilot clean-air system in new homes  

上海新建住宅將試水抗霾凈化系統(tǒng) 降低PM2.5濃度

室外霧霾頻發(fā)，室內(nèi)PM2.5污染如何防治？記者昨天在采訪中獲悉，上海部分新建住宅正在試水“新風熱回收十空氣凈化十置換送風”的“抗霾”組合系統(tǒng)。室外空氣在中度污染到重度污染的情況下，該空氣凈化系統(tǒng)在1小時內(nèi)，可將室內(nèi)PM2.5濃度降低一半，每天的電費只多花2-3度。[查看全文]

(ECNS) -- Shanghai real estate developers are testing a clean-air system to be installed in new residential buildings to meet citizens' demands for fresh air, the Xinmin Evening News reported.

The system can improve indoor air quality by getting rid of fine particulate matter, or PM2.5, from new furniture, and pollutants caused by human activity. The waste gases then would be blown outside.

When smog reaches severe levels, the clean-air systems would lower PM2.5 intensity in the house by 50 percent in only one hour, according to data from the Shanghai Real Estate Science Research Institute.

Low consumption of electricity is one of its features. One system working 24 hours in a two-bedroom apartment would add only 620 yuan ($100) a year to the electricity bill.

With cleaning and maintenance fees, the average operating cost for one household would be merely 1,500 yuan to 2,000 yuan each year.
