How the
AllerAir high efficiency air purifier system works
Allerair air
cleaners 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.
1) The pre-filter
traps larger dust particle
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 only sufficient to capture 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 and will continue working 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 were developed by the Atomic Energy Commission to trap
radio-active particles. They can capture 99.97% of particles as small as 0.3
microns. That is as small as some bacteria.
The power of
activated carbon
activated
carbon is the only safe, cost effective way to trap noxious gases and odors
What it does and how it works.
activated carbon is carbon
that has been treated with oxygen to open up millions of tiny pores between the
carbon atoms.
There are so many of these that one pound of activated carbon has a surface area
of 60 to 150 acres.
The technology used in military gas masks
activated carbon is the
substance that keeps military personnel safe from poisonous gases. It is also
used for water filtration.
Adsorption
Adsorption is the process
where certain chemicals are attracted to activated carbon and then bond to it.
The millions of pores in the activated carbon provide an enormous surface area
to trap these chemicals.
The bigger the filter, the more chemicals it adsorbs and the longer it
keeps on working
an activated carbon filter
acts rather like a sponge. When it is full it can adsorb no more. The more
carbon you have the more you can adsorb before changing the filter. AllerAir
MAC-B carbon filters have from 7 to 48 lbs and will last from 9 to 24 months.
Most off the shelf cleaners have only a few token ounces of
carbon sprayed on a mesh.
It's not enough to have any
useful long term effect.
