Outdoor air purifier reduces your waiting by 40% smoke
According to the Ministry of Environment, China’s campaign to clean up air pollution last year has reduced the level of dangerous particulate matter in the atmosphere by 11%, but there is still a long way to go before the public breathes air every day. Of the 74 cities surveyed, only 8 met basic domestic air quality standards.
Meanwhile, antifouling masks are a popular project, and start-ups that produce new indoor air purifiers are lowering prices. New inventions currently being tested in Hong Kong are causing an average of 40% of outdoor air pollution claims to be reduced (h/t to Techweb).
In the patent-pending prototype system, the air is sucked into the system from the bottom entrance, then circulated through a bag filter to remove fine suspended particles (PM10 and PM2.5) which effectively come out of the Louvre’s head.
Hong Kong has been testing at a purification station 2 m 3 m East of Queen’s Avenue in Causeway Bay, one of the best streets since March, at a cost of HK$600,000 per unit of Sino Green’s Asian Science and Technology Building (reportedly US$77.4 billion). In the earlier part of this article, an article on Techweb pointed out that it would cost $10 million to develop the project, but Sino Green explained that the figure was not accurate.)
Further quality improvements include smart controllers for more efficient management of uptime, solar panels for energy and mist cooling systems in summer.
According to Techweb, the urban air purification system will be tested at Tsinghua University in Beijing, and if all goes well, it may extend to other mainland cities in the future.
