Air filtration involves removing solid particles, like dust mites, pollen, mold, and germs, from the air using a particulate air filtration device. These filters can be made from fibrous or porous materials. Some filters also contain an adsorbent or catalyst, like charcoal, to eliminate odors and gaseous contaminants such as ozone or volatile organic compounds. There are plenty of efficient air filtration options on the market to help you breathe easier.
