And activated carbon and other substances are mainly adsorbed formaldehyde , toluene, xylene, ammonia and other harmful substances, HEPA filter has the role of filtering dust, respirable particulates. Active filterless purification: Compared with common filter-type products, the biggest benefit of high-pressure electrostatic dust collection is that the use of high-pressure electrosta...
