Austin Air HealthMate Plus HEPA (HM450) Air Purifier


Designed for chemical sensitives, The HealthMate Plus (HM450) Air Purifier removes the toughest contaminants and broadest spectrum of VOCs of any Austin Air Purifier. In addition to 60 sq ft of True Medical‐Grade HEPA filter media, the HealthMate Plus infuses Potassium Iodide into 15 lbs of activated carbon/zeolite for optimal absorption of VOCs. Significantly improves air quality in medium to large-size rooms, and is also recommended for allergy and asthma sufferers sensitive to VOCs, or for those in high smoke, particle or gas contamination areas.  Long-life HEPA saves on filter replacements.

The Austin Air HealthMate™ Plus True HEPA Air Purifier (HM450) is best suited for those with chronic respiratory issues, heightened chemical sensitivities, and susceptibility to irritation and illness from VOCs (like those you face if you just redid the kitchen cabinets, installed new carpeting, you work in a nail or beauty salon, etc.) The HealthMate™ Plus uses potassium iodide for exceptional removal of a much broader range of VOCs. Built with all the same features and filtration power as the HealthMate, the HealthMate Plus goes one step further – it is designed specifically to remove formaldehyde and the thousands of other VOCs that we all find ourselves exposed to every day.

Austin Air was founded in 1990 in Buffalo, New York by a husband trying to help his wife find relief from lifelong asthma symptoms, which he did with the Austin Air HealthMate. Today, Austin Air continues to operate out of Buffalo, and husband (now president) Richard Taylor and crew continue to build air purifiers with a "family first" mentality, knowing that cleaner air can benefit all those affected by respiratory issues.

Why Austin Air?

  • Superior Filtration ‐ Particles, Gases, Odors and VOCs

    Most Austin Airs, including the HealthMate Plus, provide 4 stages of intense filtration (5 stages with the Bedroom Machine). What sets the HealthMate Plus apart from other True HEPA systems is its filters. The HealthMate Plus contains 60 square feet of True Medical-Grade HEPA filter media (to trap sub-micron particles). The HEPA is surrounded by 15 pounds of carbon/zeolite impregnated with potassium iodide (to 'adsorb' odors, gases, formaldehyde, ammonia, and carbon monoxide). Potassium iodide increases carbon's ability to remove more formaldehyde and the broadest range of other VOCs. The specially made activated carbon is highly porous, producing a larger surface area that extends its performance. Two pre-filters block larger particles – one that surrounds the carbon/zeolite/potassium iodide filter, the other that wraps around the interior of the unit's housing.

    No other air cleaner in its class can match the performance of the HealthMate Plus. It simply "out filters" other brands. Austin Air backs this up by providing a 5-Year Pro-Rated Filter Warranty, in addition to its 5-Year Mechanical Warranty.

  • Designed for Performance

    Austin Air machines process 250 cubic feet of air every minute (125 cubic feet for the junior models). Air is drawn in from all sides of the unit via its 360° air intake grilles, where it immediately begins to be pulled through Austin's 4-stage or 5-stage filter, which progressively removes dust, hair, fibers, odors, gases, VOCs, Radon daughters, pollen, pet dander, mold spores, bacteria, viruses, and other allergens and contaminants.

    Austin Airs feature high-velocity airflow (75-400 cfm for standard-size units, 50-200 cfm for junior sizes), which helps to quickly create a pocket of clean air around the user. Run on high with the door closed, and assuming four air changes per hour, Austin Airs can clean a 465 sq ft room in 15-20 minutes (or a 480 sq ft room in 30-40 minutes for junior sizes).

    Austin Airs produce 50-66 dBA (decibels) of noise, depending on fan speed selected. Customers report it to be very quiet on the low setting. Set at high, the sound approximates that of a normal conversation. Many customers use the high setting for quick or maximum air cleaning.

    Austin Airs are solidly made. Each unit is built using 22-gauge welded steel that does not rattle or vibrate, even at max speed. A powder-coated finish (baked at 375°F) does not off-gas and lends durability. Standard-size models come equipped with heavy-duty casters for easy portability. Casters are optionally available for Junior-size models.

    Austin Airs save energy. Energy efficient PSC motors, equipped with a centrifugal fan, use less energy than some light bulbs. Electricity to run a standard-size unit at max draw (132 watts) should cost about 1.5 cents an hour, and about 1 cent an hour to run a junior-size unit at max draw (82 watts), based on average residential electricity rates projected by the United States EIA for 2014-2015. Energy costs for each size will be less when run on the lower fan speeds.

  • Made in USA

    Austin Air produces everything here in the USA out of its 480,000 square-foot facility in Buffalo, New York – the largest air cleaner manufacturing facility in the world. While made on American soil, Austin Airs can be found helping people in homes throughout the world. Austin Airs are also used in hospitals and clinics, and have even been called to national service by the U.S. Army Corps of Engineers, and to assist FEMA and the Red Cross in the aftermath of 9/11. When clean air is crucial, and lives depend on it, Austin Air remains the #1 choice.

  • Integrity in Claims about the Product and Test Results

    Austin Air believes in being straight with consumers about what its products can and cannot do. The company does not use private testing, but rather each air purifier undergoes tough government and third-party testing, whose stringent standards must be met to ensure products perform as claimed. For example, wide-ranging product tests conducted by Battelle Laboratories (a well-respected testing laboratory for the Army Corps Engineers at the U.S. Army Aberdeen Test Center) have included flow design and rate, as well as gas, odor and sub-micron particle removal.

  • Ease of Use and Low Maintenance

    Austin Airs come ready to be plugged in. Each unit comes with two filters ‐ the outer pre-filter, and the HEPA filter assembly. All models use a manual rotary dial to switch between 3 fan speeds ‐ High (III), Medium (II) and Low (I). Austin Airs can be placed anywhere in a room, but should be at least 4-8 inches from a wall for maximum effectiveness.

    Austin Air filters are designed to last five years, which saves on the hassle and cost of frequent filter replacements. If filters do need to be replaced, the process is straightforward and should take only a few minutes. Although the bottom cover must be removed using a Phillips-head screwdriver (4 screws), filters just lift out for easy replacement. The outer surface of the units need only be vacuumed monthly to remove dust particles that may accumulate on the exterior air intake grilles.

  • 1500 sq. ft. (1 air change per hour)
  • 875 sq. ft. (2 air changes per hour)

Austin Air HealthMate™ Plus Instructions

Please see Owner's Manual tab for setup and operating instructions, plus full instructions on changing the filters. A one-page set of instructions on filter changes is also provided.

General on Pre-Filter:

  • The outer Stage 1 pre-filter (which you can see can through the unit's perforated grille) can last for years with regular cleaning. Just vacuum the outer surface of the unit monthly (you do not need to open the unit) by using the brush attachment of your vacuum to remove dust from the outside of the unit and large particles from the pre-filter.

  • If you do not maintain the outer Stage 1 pre-filter or if it becomes damaged, genuine Austin Air replacement filters are available through National Allergy.

General on HEPA Filter:

  • Austin Air filters are designed to last up to 5 years. However, please remember that the filter's service life is related to the volume of air that passes through the air purifier and the amount of contaminants in the air. If your indoor air has an unusually high level of airborne particulates, smoke or gaseous 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 the HEPA filter pack if you notice a significant drop in clean, odorless air flow.

  • Important ‐ For first-time use or any time you change the HEPA filter pack, it is important that you run the purifier on the High (III) setting for at least the first hour of use. After the first hour, turn the Speed Control Setting to the desired level.
