The IQAir MultiGas Media

The IQAir MultiGas media offers both, physical and chemical filtration processes. As a result, the MultiGas media is able to trap a broader range of gaseous contaminants and odours than conventional room air purifiers.

HIGHEST QUALITY CARBON

The IQAir VOC gas and odour control media consists of special coal-based activated carbon pellets of a granular, porous nature.  The activated carbon media is composed of a non-impregnated, extruded carbon, ideal for the adsorption of gaseous contaminants with higher molecular weights, including a wide variety of odour causing organic compounds, volatile organic compounds (VOCs), solvents, alcohols, aromatic hydrocarbons, alkenes and esters.

This uniquely-formulated activated carbon used in the MultiGas media provides higher performance for residential and light commercial applications. IQAir's activated carbon is also activated for a maximum proportion of micropores.
It is these optimised micropores that allow for maximum removal activity at the gaseous pollutant levels typically encountered in home, office and light commercial environments.
Conventional air cleaners use gas control media based on a purely physical filtration process, such as activated carbon and zeolite.

CHEMISORBER

For control of gaseous contaminants with a low molecular weight, such as formaldehyde and hydrogen sulfide, the MultiGas media also contains a chemically active media, called ChemiSorber. This media is made of activated alumina* (Al2O3) impregnated with potassium permanganate (KMnO4).
This non-toxic media first physically binds selected contaminant molecules and then chemically destroys them through an oxidation process. However, no oxygen or ozone is generated, since the process is media based only.
It is this combination of physical adsorption and chemisorption, which is at the basis of the broadspectrum gas and odour control capabilities of the MultiGas media providing optimum adsorption, absorption and oxidation of a wide variety of gaseous contaminants.

Multigas Filter media is used in the following models:

  • Healthpro 150 & 250
  • Multigas GC & GCX
