Research Studies and Facts

Activated carbon air filters are the most effective type of filter against chemicals, gases, cigarette smoke and other odors.

How Activated Carbon Filters Work

Activated carbon air filters consist of a vast system of pores of molecular size. These pores are highly adsorbent, forming a strong chemical bond/attraction to odorous, gaseous, and liquid contaminates, especially organic chemicals/compounds.

Activated Carbon Filter Facts and Studies

  • Activated carbon air filters trap odors and chemicals in highly absorbent granules (or pores), which look like a hard scrub brush.

  • Activated carbon is a charcoal that is treated with oxygen in order to open up millions of tiny pores between the carbon atoms, resulting in a highly adsorbent material.

  • Originally used in World War II to protect U.S. soldiers from chemical warfare agents.

  • In a study commissioned by the U.S. Dept. of Energy, activated carbon filters were found to removed 60-70% of airborne ozone compared to filters without activated carbon.

  • Another study commissioned by the U.S. Dept. of Energy found that activated carbon filters removed harmful VOC's (Volatile Organic Compounds) by 60-80%, and formaldehyde by 25-30%.

  • According to a report released by the Centers of Disease ControlDept. of Health and Human Services, and the National Institute for Occupational Safety and Health, activated carbon is an excellent adsorber/absorber of most organic chemicals.
