Product Description

The IQAir GC MultiGas Filter provides for a wide spectrum of air purification needs.


Charcoal is carbon. “Activated” charcoal is charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms, resulting in highly porous charcoal with surface areas of 300-2,000 square metres per gram. These so-called active, or activated, charcoals are widely used to ADSORB odorous or coloured substances from gases or liquids.


The word ‘adsorb’ is important here. When a material adsorbs something, it attaches to it by chemical attraction. The huge surface area of activated charcoal gives it countless bonding sites. When certain chemicals pass next to the carbon surface, they attach to the surface and are trapped.


Activated charcoal is good at trapping other carbon-based impurities ("organic" chemicals), as well as things like chlorine.


However, many other chemicals are not attracted to carbon at all -- sodium, nitrates, etc. -- so they pass right through. This means that an activated charcoal filter will remove certain impurities while ignoring others. That’s why IQ Air filters contain not only activated carbon but also granules of permanganate, which adsorbs chemicals not adsorbed by charcoal.


Once all of the bonding sites are filled, the filter stops working and must be replaced.


Odours Controlled: pets, musky smells, cooking odours, paint odours,off-gassing from plastics, new carpets, smog, fumes, industrial pollution, tobacco smoke and general air pollution. Importantly -  Its  MultiGas (MG) media will remove deadly nitrogen oxides (NOx).  This media is also found in the HealthPro 150/250 models and GCX-MG model.




IQAir GC MultiGas Cartridges

IQAir's activated carbon is 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 asactivated carbon and zeolite.

For control of other gaseous contaminants with a low molecular weight, such as formaldehyde and hydrogen
sulfide, the MultiGas media 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 carbon/permanganate (physical adsorption and chemisorption), which is at the basis of the broadspectrum
gas and odour control capabilities of the IQAir MultiGas media.
