Purafil is made from potassium permanganate. It works in a different manner than carbon. Harmful contaminant gases such as Formaldehyde, hydrogen sulfide, sulfur dioxide, nitrogen dioxide, nitric oxide are actually oxidized and are trapped within the pellet. This Product is generally not used as a sole media. Aireox has researched and found that mixing Purafil and carbon is more effective. See Purafil / Carbon Mix.
Activated Carbon – Is a high grade carbon
that is well suited to airborne chemical removal. Activated carbon is
accomplished by using a superheated steam in the carbonization process
that causes micropores to form in the carbon. This allows the carbon a
much greater surface area and provides a greater capacity for gas and
odor absorption.The two most common activated carbons are: Coconut and
Bituminous. Beware! Some activated carbon is acid washed. Aireox carbon is not acid washed.
A coconut carbon media by itself removes for example using a scale from 1-4
(4 being the highest)
Formaldehyde -2 Nitrogen Dioxide – 2
When we add purafil to the carbon it brings these numbers up to a “4” making our “PC” mix the most popular media.
Some common Contaminants removed by this mixture are hydrogen sulfide, sulfur dioxide, nitric acid, formaldehyde, acetic acid, alcohols and VOC’s like Benzene chlorine, ozone, toluene, phenol, methyl alcohol and tobacco smoke.
Removes: Mold Spores, Dust Mites, Pollen, Formaldehyde, Irritating Gases, Offensive Odors and much more.
