上海新建住宅将试水抗霾净化系统 降低PM2.5浓度

室外雾霾频发，室内PM2.5污染如何防治？记者昨天在采访中获悉，上海部分新建住宅正在试水“新风热回收十空气净化十置换送风”的“抗霾”组合系统。室外空气在中度污染到重度污染的情况下，该空气净化系统在1小时内，可将室内PM2.5浓度降低一半，每天的电费只多花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.
