Charcoal air purifiers (or a charcoal filter, also called “activated carbon”) operate by absorbing odors and gases from the air. The size and cost of charcoal air purifier filter can vary greatly, but it works well because the millions of tiny cells within the charcoal are not only very porous; they also attract and hold gases and odors.
It can absorb chlorine and other chemicals in the water, and toxic gases in the air so it is also used in water purifiers, and military gas masks. The charcoal filters must be replaced after it has absorbed enough gas to fill all the available cells.
