With the development of building technology and the use of a large number of new materials, people built the house more and more sealed, and according to the relevant departments to investigate the city residents in about 80% of the time spent in the room, that is, the city Residents spend most of their time in their increasingly sealed houses. Indoor air in the presence of harmful substances higher than the outdoor several times. Improve the quality of indoor air more and more attention by the human, home appliance industry, air purification equipment market in the form of optimistic. While the central fresh air system outrageous access to wide acclaim.
