Purafil Media

Purafil media are engineered to target airborne gaseous pollutants. These pollutants, which are too small to be seen by the naked eye, cannot be trapped by even the most efficient particulate filter. Purafil specializes in the engineering and manufacture of dry-chemical pellets called “media” to trap and eliminate thousands of gaseous pollutants.


Purafil manufactures many different media using different active ingredients. Each Purafil media targets specific gaseous pollutants. We customize your Purafil system using one or more Purafil media, depending upon the types and levels of gaseous pollutants present in your environment. 


Purafil offers a range of different types of media, the selection of which depends on the contaminant challenge. 

Purafil Select

  • Activated alumina based system 

  • Potassium permanganate and sodium bicarbonate impregnation system
