Aller Air Home Air Filters - How do they work?

Aller Air home air filters have a unique air filtration system that delivers the purest air possible. The air first passes through a pre-filter where large particles are removed. After this, the air passes through a high quality coconut shell activated carbon filter, the amount dependent upon the model purchased, where gases, chemicals, odors and vapors such as second hand smoke or other ambient air toxins are adsorbed. The air then enters two anti-microbial filters before going on to the 80 square feet of HEPA media. This is the point where 99.97% of all particulate larger than .3 microns are removed from the air before being sent back out into the room.

If you choose the UV model, the air is further purified by circulating it around a UV lamp, exposing the air long enough to kill pathogens. Aller Air's UV model will lower bacterial counts lower than if it were done through ventilating the room at a rate of 100 air exchanges per hour. The normal rate of air exchanges for most homes over the same period of time is no more than one half dozen times. It is for this reason, that HEPA filters are recommended by more allergists, medical professionals and clean air consultants, than any other filter system available.

How AllerAir high efficiency home air filters work.
AllerAir air cleaners use a 4 phase filtering system. In the order that the air passes through them they are: pre-filter, the mass activated carbon bed (MAC-B) filter, the 2 anti-microbial filters and the HEPA filter.

1. 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.

2. The mass activated carbon bed (MAC-B) filter adsorbs gases and odors. (Adsorb: no it's not a typo. This is the process by which activated carbon captures gases and odors.) Most off the shelf air cleaners 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 in the air and for only a short period of time. The MAC-B carbon filter has pounds of activated carbon (from 7 to 160 lbs.) that will trap 90% of gases and odors that pass over it. The filter is effective for many months before needing to be replaced.

3. The 2 anti-microbial filters kill the airborne microbes that pass through them.

4. The HEPA filter traps the airborne particles. These filters, which were developed by the Atomic Energy Commission to trap radioactive particles, can capture 99.97% of particles as small as 0.3 microns. That is as small as some bacteria.

Other features not readily available with other brands of home air filters are:

    Metal housing
    High efficiency unsheathed motors
    Separate HEPA and CARBON filters
    Anti-microbial filters
    Patented dual air flow circulation

The result is healthy clean air in your home or office.
