Best Carbon Air Filter in 2020

Carbon air filters a made of activated charcoal (or activated carbon). It has a huge surface area – up to 30,000 sq ft due to the special processing to make small low volume pores (microporosity) for adsorption of contaminants. The filters are usually used in air and gas purification to eliminate odor, oil vapors and other contaminants from the air. They are built on a 1-stage or 2 stage filtration principle with activated charcoal embedded inside the filter media. Carbon air filters are used even in spacesuit life support systems.
