Can the air purifier really remove formaldehyde?
Sep 21, 2018

Misunderstanding a "foreign monk good chanting" Joint venture products thousands of, import brands tens of thousands of yuan, air purifier is becoming a home appliance in the "upstart", consumers are flocking to, or even not all imports do not buy. In fact, these air purification products from Germany, Finland or the United States, according to the local Air environment research and development, may not be suitable for our country.


Misunderstanding two technology is not high price high Technicians almost dissected all types of air purification products on the domestic market, and found that "dust + filtration" is the mainstream. The main components of this type of purification technology are fans and filter screens. As long as the power is large enough, adequate ventilation, indoor environment is relatively closed, a certain time can be air "suction". The old air came in, and the new air went out through layers of filters, and fine particles were captured and deposited. As long as the filter is dense, PM2.5 and even finer particulate matter can be "arrested".


Misunderstanding three purification standards to be refined At present, China's standards for air purifier technology are not uniform, and update slowly, can not adapt to the development of indoor pollutants in China's current situation. Ma Xinzheng suggested that China should be issued as soon as possible with mandatory air purifier technical standards, while the purification function of the air purifier is classified and identified in the product description of the type of air pollutants, and mark the applicable area, purification and energy efficiency. At the same time, the introduction of third-party testing institutions to monitor the actual use of air purifiers.
