Activated charcoal can remove VOC, remove odors and help to control humidity (by removing excess moisture from the air). Millions of tiny pores help to trap the harmful particles. Activated carbon for air purification, using high-quality virgin coal and through deep activation and unique pore size adjustment process, have rich holes and the size of the hole is slightly larger than the toxic gas. The surface area of the activated carbon is above 1300m2/g, so it has high efficiency adsorption capacity for benzene, formaldehyde, ammonia and other toxic Hazardous gases. It can effectively remove the indoor air gaseous pollutants and harmful odor substances, and thus to reduce pollution, clean air purposes. For industrial areas: a variety of workplace deodorant detoxification and air conditioning filters, air purification machines, central air conditioning filter system, air filters, car filters and so on.
