All standard size units are interchangeable with all standard size filters. So, if you purchased a standard size HealthMate® and would like to upgrade to a Pet Machine®, simply purchase a replacement Pet Machine® filter.
You can check the size of your existing filter by looking for a label on the underside. Model HM400 indicates standard size filter.

Product FAQs
Austin Air Systems Product FAQs
How long has Austin Air Systems been manufacturing medical grade HEPA purifiers?
Since 1990, over thirty years!
Why are Austin Air's products superior to others in the purifier market?
Austin Air’s filters and proprietary 360° air intake system make us superior. Austin Air uses true medical grade HEPA filter paper, 60 square feet total, in their purifiers. We also use Activated Carbon and Zeolite (780 cubic inches to be exact) which remove chemicals, gases and odors (HealthMate, and Bedroom Machine). Our HealthMate Plus filter features Potassium Iodide Impregnated Carbon and Zeolite, which removes Volatile Organic Compounds (VOCs), formaldehyde, benzenes, chemicals, gases and odors. Our Allergy Machine and Bedroom Machine both feature an advanced military carbon cloth (HEGA) placed inside the filter. This provides an extremely large surface area for adsorption of chemicals, gases, viruses and bacteria.
Other companies have plastic products and/or use sprayed on paint, so their products emit harmful gases. Austin Air's products are made of steel and have a powder coat paint, which is baked on. This means that our purifiers do not off gas.
Austin Air's products have a high-velocity airflow, which creates a clean air pocket around the user. The 360° intake system draws air into all sides of the purifier and then passes it through the filter. If you turn on an Austin Air cleaner next to a competitor’s unit, you can really feel the difference. Austin Air purifiers clean the air in most bedrooms in less than 15 minutes.
Austin Air Cleaners use energy efficient PSC motors which means that running your purifier uses less energy than some light bulbs!
Austin Air offers a 30-day, no questions asked money back guarantee. Your Austin Air purifier is warranted to be free from defects in material and workmanship for a period of 5-years from the date of purchase. We also offer a 5-year pro-rated filter warranty, by far the most comprehensive in the industry.
Once you experience Austin Air cleaned air, you will agree that our products are superior.
What is the difference between the four Austin Air filter types?
All of our 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)
The filters differ as identified below:
The Allergy Machine:
STAGE 3 – 60 sq. ft. of True Medical Grade HEPA. Removes 99.97% of all particles larger than 0.3 microns and 95% of all particles larger than 0.1 microns.
STAGE 4 – Military Grade HEGA Carbon Cloth. HEGA (High Efficiency Gas Arrestance), providing an extremely large surface area for adsorption of chemicals, gases, viruses and bacteria.
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 95% 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, benzenes, 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 95% 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 95% 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
What are the pre-filters made of?
Our pre-filters are made of bonded polyester.
What exactly is a HEPA filter?
The HEPA (High Efficiency Particle Arresting) filter was developed by the U.S. Atomic Energy Commission to filter out sub-micron particles. All true medical grade HEPA is laser-tested and must remove a minimum of 99.97% of all particulate matter greater in size 0.3 microns. Austin Air’s HEPA filters also remove 95% of all particles larger than 0.1 microns. All Austin Air purifiers feature true medical grade HEPA filters.
