How the Allerair air purifier, air cleaner and air scrubber High Efficiency air cleaning system works.

Allerair air cleaners / purifiers / scrubbers use a 4 phase filtering system. In the order that the air passes through them they are: the pre-filter, the mass activated carbon bed (MAC-B�) filter, the 2 anti-microbial filters and the HEPA filter.

• The pre-filter traps larger dust particles and is easily removed and cleaned with a vacuum cleaner. It acts to stop the larger particles such as dust and lint from clogging the other filters.
• The mass activated carbon bed (MAC-B�) filter adsorbs gases and odors. (Adsorb: the process by which activated carbon captures gases and odors.) Most off the shelf air cleaner, air purifier products have a few token ounces of carbon sprayed on the pre-filter. This is not sufficient to capture more than a small amount of the noxious gases and odors (formaldehyde, fluorine gas, nail salon chemical fumes, odors, HCL, fragrances, etc.) in the air and for only a short period of time. The MAC-B� carbon filter comes with pounds of activated carbon (from 7 to 160 pounds) that will trap 90% of gases and odors that pass over it and for many months before needing to be replaced.
• The 2 anti-microbial filters kill the airborne microbes that pass through them
• The HEPA filter traps the airborne particles. These filters, which were developed by the Atomic Energy Commission to trap radio active particles, can capture 99.97% of particles as small as 0.3 microns. That is as small as some bacteria.

Other Allerair air purifier / cleaner filtering options for special cases:

• UV Light , Ultraviolet light option is available in the the 400 CFM series (4000, 5000, 6000, and 8000 series)
• ULPA filters are like HEPA filters but the ability to filter as small as 0.1 micron and capture 99.999% of solid matter.
• The importance of a metal housing to avoid plastic off gassing.
• AllerAir air cleaners and air purifiers are housed in a baked enamel metal casing. Unlike plastic, metal casings are completely inert and do not give off plastic vapors into the indoor air.
