Here is a simple explanation specifically for activated carbon filters in air filtration:
-
Air flows through the filter → It contains dust, Odours, gases or pollutants.
-
The activated carbon filter consists of carbon with many tiny pores → this gives it a huge surface area.
-
Pollutants, Gases and odour molecules stick to the carbon (absorption).
-
Clean air comes out again.
👉 Typical applications in air filtration:
-
Room air purifier → Against odours, Cigarette smoke, volatile chemicals.
-
Car air conditioning → Filters exhaust fumes and odours from outside.
-
Industrial plants → Removes toxic or unpleasant vapours.
In short:
An activated carbon filter acts like an odour and pollutant sponge in the air.
