Austin Air Filter Types

All of Austin Air filters have the same first two stages of filter as follows:

STAGE 1 – Large Particle Pre-filter. Removes particles easily seen by the naked eye (e.g. dust, hair and pet dander)

STAGE 2 – Medium Particle Pre-filter. Removes small to medium size particles (e.g. molds, spores and pollen)

 

HealthMate:

STAGE 3 – Over 780 cubic inches of Activated Carbon and Zeolite. Removes chemicals, gases and odors.

STAGE 4 – 60 sq. ft. of True Medical Grade HEPA. Removes 99.97% of all particles larger than 0.3 microns and 99% of all particles larger than 0.1 microns.

HealthMate Plus:

STAGE 3 – Over 780 cubic inches of Activated Carbon, Potassium Iodide Impregnated Carbon and Zeolite. Removes Volatile Organic Compounds (VOCs), formaldehyde, benzene, chemicals, gases and odors.

STAGE 4 – 60 sq. ft. of True Medical Grade HEPA. Removes 99.97% of all particles larger than 0.3 microns and 99% of all particles larger than 0.1 microns.

The Bedroom Machine:

STAGE 3 – Over 780 cubic inches of Activated Carbon and Zeolite Removes chemicals, gases and odors.

STAGE 4 – 60 sq. ft. of True Medical Grade HEPA. Removes 99.97% of all particles larger than 0.3 microns and 99% of all particles larger than 0.1 microns.

STAGE 5 – Military Grade HEGA Carbon Cloth. HEGA (High Efficiency Gas Arrestance), providing an extremely large surface area for adsorption of chemicals, gases, viruses and bacteria.

 

TERMS:

  • HEGA (High Efficiency Gas Arrestance) is a term that is unique to Austin Air.  A HEGA filter is a military carbon cloth filter medium that is featured in our Allergy Machine and Bedroom Machine.
  • Activated carbon is effective at removing gas molecules and odors.  Activated carbon is the most common element found in military gas masks.  The most common method of activating carbon is a two-stage steaming process, which enlarges the carbon’s surface pore size.  This in turn produces a more accessible internal surface area, allowing for greater odor and gas adsorption.
  • Zeolite is a natural mineral that has the distinct capability of adsorbing certain gas molecules.  Zeolite is particularly effective in adsorbing formaldehyde, ammonia and carbon monoxide.
