See a brief video showing Austin Air HEPA/HEGA Filtration:

Austin Air HEPA/HEGA Filter Pack (FR205) replaces all filters that come with the Austin Air Allergy Machine™ Jr. (HM205) and Baby's Breath (HM205) air purifiers. The 4-stage filtration system provided in this filter pack is designed for best all-around protection from allergies, asthma and harmful odors, gases and VOCs. The system integrates true, medical-grade HEPA, which cleans air of even the smallest airborne particles, with a military-grade carbon cloth to remove harmful chemical gas contaminants and become what is known as HEGA (High Efficiency Gas Absorption).  Included in the FR205 4-Stage Filter Pack are:

  • Stage 1 - Large Particle Permafilt Pre-Filter - removes particles easily seen by the eye (dust, hair, pet dander)
  • Stage 2 - Medium Particle Pre-Filter - removes small to medium-size particles (pollen, molds, other spores)
  • Stage 3 - 30 sq. ft. of Certified HEPA - removes allergens, bacteria, viruses, and other particulates:
    • 99.97% of all particles larger than 0.3 microns
    • 95.0% of particles larger than 0.1 micron
  • Stage 4 - Military-Grade Activated HEGA Carbon Cloth - absorbs more gases and chemical contaminants

Because you see the pre-filter through the air cleaner's grille, choose the Black filter pack for Black-Silver-Midnight Blue units or the White filter pack for Sandstone-White units. Choose White or Black for the Baby's Breath models.


  • Replacement HEPA/HEGA Filter Pack (FR205) includes all 4 filters to replace the set that comes in the unit
  • Includes 30 sq. ft. of true, medical-grade HEPA to filter 99.97% of allergens, bacteria, viruses, and more to 0.3 microns
  • Integrates a military-grade HEGA carbon cloth after the HEPA for optimum removal of reactive gases, odors and VOCs
  • 2 pre-filters trap larger particles and prolong the life of the HEPA
  • Fits Austin Air's Allergy Machine Jr. (HM205) and Baby's Breath air purifiers. Will also fit any junior-size Austin Air purifier.

Note:  The (outer) Stage 1 Permafilt Pre-Filter (F200) by Austin Air may also be purchased separately.

Filter Replacement for Austin Air Purifiers

Please see Owner's Manual tab for full instructions on changing the HEPA filter pack.


  • Austin Air filters are designed to last up to 5 years. Remember that the filter's service life is related to the volume of air that passes through the purifier and the amount of contaminants in the air. If your indoor air has an unusually high level of airborne particulates or contaminants, the filter's service life may be shortened.
  • Regular maintenance helps to prolong the life of the HEPA filter. Keep the area surrounding the air purifier clean, and be sure to vacuum any dust buildup on the outside of the unit, especially on the 360° air intake grille.
  • Replace HEPA filter pack if you notice a significant drop in clean, odorless air flow.
  • Filter change is quick and easy.

The Austin Air Filter is the best room air cleaner I've ever found. Maintenance is so easy. The pre-filter needs to be changed every 6 months, and then I vacuum the main filter. I have 4 of these around the house (I have severe allergies) and 2 of them have already gone over their 5 year estimated lifetime. All other air filters make you change the pre-filter every 3 months and the main filters yearly - they are too expensive and it's too dirty a job, plus they don't work near as well as the Austin Air Filter.
I've had my Austin Air for years. It's a quiet running air cleaner compared to other HEPA cleaners, and it's easy to maintain. High quality. If it broke, I would go buy another one. I've had mine for over 10 years now, I think, and still running fine.
