There are four main types of air filtration:

	Electrostatic filters attract particles to a statically charged filter or screen. Filter efficiency declines rapidly, making these the least effective filters.
	Electronic Air Cleaners charge airborne particles to be captured by a series of metal plates. These plates become covered and, therefore, ineffective very quickly.
	Ionizers charge airborne particles causing them to adhere to nearby surfaces such as walls and floors where they can be reintroduced into the air.
	Media filters “strain” suspended particles from the air. The best media filter and, in fact, the best air filter of all is the HEPA (High Efficiency Particulate Air) filter.

HEPA filtration is the most researched filtration method available in the world today! It's documentation in a wide range of applications assures the user of it's effectiveness

What Is 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. 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.

What Sets Amaircare® HEPA Apart From the Competition?

Americair manufactures 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.

Measuring in Microns

Airborne particulates are measured in microns. One micron is equal to one-milionth of a meter, or 1/25000th of an inch

Amaircare HEPA Filter Systems

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.

Stage 1 - Pre-filter

All Amaircare® 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.

Activated Carbon Pre-filters: Activated 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

Foam Pre-filters: 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.

Filter Life: 6-12+ months

Stage 2 - HEPA Filters

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.

Stage 3

Carbon V.O.C. 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.

Carbon/Zeolite 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.

XR-100 Auto Unit

Amaircare® Auto Filter

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 Pre-filter

The carbon pre-filter captures large particulates and odours. It is composed of Activated Carbon 200% impregnated non-woven, fire retardant, polyester filter media

Stage 2 - Electret Charged Filter Media

This sub-micron 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. Filter

A Zeolite impregnated non-woven polyester filter which adsobs* gaseous contaminants.

* Adsorb - to absorb through a process of molecular bonding.

Filter Life: 4-6 months
