Amaircare HEPA Filter
All Amaircare HEPA
systems come standard with a 3 stage filtration process. A pre-filter
to capture large particles such as dust, a HEPA filter which captures
99.97% of particles from .3 microns or larger, and a V.O.C. filter
for removal of gasses and odours.
of an Amaircare 3000 Unit
Stage 1 - Pre-filter
pre-filters are designed to prolong the life of the HEPA filter.
This is done by capturing the visible dust and particulate from
the air. This keeps the larger particles from clogging the HEPA
filter so the HEPA can be used strictly for filtering the smaller
particles that cannot be seen with the naked eye.
carbon is a form of charcoal which has the ability to remove impurities
from air, gas, and liquids. When various impurities come into
contact with the activated carbon, the constituent molecules become
trapped in tiny capillary passages on the surface of the carbon
in a process called adsorption. Due to differences in molecular
structures, some impurities are more readily adsorbed than others.
- Filter Life:
3 to 6 months
To make the pre-filters last longer,
Amaircare® has introduced a foam pre-filter to some of their
filtration systems. This foam filter is washable, which drastically
increases it's life. The filter can be removed, washed, and placed
back onto the unit (when dry). The filter is useable until it
becomes stretched out of shape and no longer fits the unit properly.
This foam pre filter does not contain Activated Carbon.

Stage 2 - HEPA
HEPA is a filtration
standard created by the U.S. Atomic Energy Commission. HEPA filter
media is proven to be 99.97% efficient @ 0.3 microns (a micron
is 1/1,000,000 of a meter or 1/25,000th of an inch). Due to their
extremely high efficiency, HEPA filters have become widely used
in medical, electronic and industrial applications. HEPA filters
are composed of a various sized borosilicate fibers, which are
pressed together to form a netlike structure with openings large
enough for air to pass through but too small for most particulates.
its own Amaircare® brand HEPA filters. The filter media comes
off a roll and is pleated for optimum surface area. Filament is
bonded to the filter to provide structural support and even pleat
spacing. After the pleating process, the filters are enclosed
in protective screens and cast in food-grade plastisol at both
ends for a 100% air seal. Each finished filter is tested for 99.97%
efficiency, with a laser particle counter.
Blankets: Like the Carbon
Pre-filters, the Carbon Inner Blanket is a form of charcoal which
has the ability to remove impurities from air, gas, and liquids.
When various impurities come into contact with the activated carbon,
the constituent molecules become trapped in tiny capillary passages
on the surface of the carbon in a process called adsorption. Due
to differences in molecular structures, some impurities are more
readily adsorbed than others.
V.O.C. Cartridges: V.O.C.
cartridges capture contaminants the same way as a Carbon Blanket,
but they use solid carbon and zeolite pellets which have a comparably
larger surface area. This makes V.O.C. cartridges the filter of
choice for situations where V.O.C. removal is a prime objective.
Amaircare's only filtration
system that is not HEPA. The XR-100 is small enough to literally
take anywhere. To save on size, the HEPA filter has been replaced
with an Electret Charged filter.
Stage 1 - Carbon
The carbon pre-filter
captures large particulates and odours. It is composed of Activated
Carbon 200% impregnated non-woven, fire retardant, polyester
Stage 2 - Electret
Charged Filter Media
particulate filter is charges so that it attracts and holds
sub-micron particles in the air stream such as dust, pollen,
cigarette smoke, bacteria, vehicle emissions, etc.
Stage 3 - V.O.C.
A Zeolite impregnated
non-woven polyester filter which adsobs* gaseous contaminants.
* Adsorb - to absorb
through a process of molecular bonding.
