Activated carbon is a highly porous carbon material with a massive surface area. If you were to just open 2 grams of activated carbon, that would result in the area of half a football field! (2000+ sqm)! Due to the unique physical chemistry of activated carbon, odorants are highly attracted to and highly bound to carbon molecules. This principle is known as the "Van-der-Waals reaction". Due to activated carbon's massive surface area and the "Van-der-Waals reaction," activated carbon is able to bind many scents at once, in a big way. Activated carbon has been used successfully in homes for a long time - for example; In exhaust fans, odor filters in refrigerators, water filters and shoe soles.
