The IQAir PreMax MG (Multi-Gas) Filter is a dual purpose filter which contains:
The IQAir PreMax Multi-Gas Filter is usually shipped with the IQAir HealthPro 150, however owners of the HealthPro 100 ‘Allergen’ can use the PreMax Multi-Gas filter instead of the standard PreMax Filter.
Under normal indoor storage conditions the particle filters (i.e., PreMax- and HyperHEPA-Filters) have a virtually unlimited shelf life.
Under normal indoor storage conditions and if boxes remain unopened, the V5-Cell Gas & Odour Filter will also remain usable for at least 5 years.
The PreMax MG is a dual purpose filter.
The uniquely-formulated activated carbon used in the MultiGas media provides higher performance for residential and light commercial applications. 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 as activated carbon and zeolite.
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.
