The Austin Air HealthMate HM400 combines two proven filter technologies to provide the best overall performance in an air purifier for mid-size rooms. The Austin Air HealthMate HM400 is recommended for allergy and asthma sufferers to help remove a variety of airborne triggers, including dust, pollen, mould spores and pet dander. It is also an excellent choice for the control of harmful airborne pollutants (e.g., particles produced by radon and combustion), toxic chemicals and gases, and unpleasant odours.

The Austin Air HealthMate HM400 air purifier features a Permafilt pre-filter that is designed to be easily vacuumed from the outside, making this unit simple to maintain and eliminating costly 3-month pre-filter changes. The Austin Air HealthMate HM400 uses a combined medical-grade HEPA and 15 lb. activated carbon/zeolite filter that only needs to be replaced once every five years. This air purifier also features a perforated 23 gauge steel, 360 degree air intake housing with over 5 square feet of intake area for exceptional air gathering capability, three fan speed settings, and a louvered air flow output directed to one side from the upper deck.

The Austin Air HealthMate HM400 is perfect for living or family rooms, master bedrooms, small single-room apartments and enclosed offices. It is also an ideal choice for those who wish to operate an air purifier at a lower fan speed to minimize noise while maintaining high effectiveness. With a baked-on powder-coated finish and four colours to choose from, the Austin Air HealthMate HM400 blends easily into almost any décor.

“I just wanted to let you know that I have set up the 5 Austin Air HealthMate HM400 air purifiers that I purchased from you in my 5 dental operatories and am pleasantly surprised that they are not loud even when the fan speed is set to high. Also the foot print of the unit is compact enough to allow easy placement within the confines of the room. I just ordered two more units for the reception and waiting room! Thank you again for your fast and efficient service.”
Christopher S., Toronto, ON

“After using the Austin Air HealthMate HM400 air purifiers for about a month in our dental operatories, I can testify that they do an excellent job in purifying the air! Our hygienists and assistants are so pleased with them, and I’ve heard them say many times that they really feel the difference in the air quality after we put the air purifiers in operation! Thank you Robert, for providing your expertise and helping me to decide which air purifier was the right one for my purposes!”
Celso C., Kitchener ON

“I purchased an Austin Air HealthMate HM400 for myself when my asthma, exacerbated by an unhealthy, ozone-emitting electrostatic air purifier, became difficult to control. I experienced instantaneous improvement in my asthma symptoms, and as an unsuspected bonus, am no longer waking up with a stuffy nose! We now have another Austin Air air purifier installed in the kitchen where we operate a gas stove. As gifts for our loved ones, my husband and I purchased 3 more Austin Air HealthMate units. My mother, who has Pulmonary Fibrosis, now sleeps more comfortably in her home, and the stale smell in our adult son's bedroom is a thing of the past.”
D. Brown, Ste-Anne-de-Bellevue, QC

“I just wanted to let you know how pleased I am with the Austin Air HealthMate HM-400 air purifier. I'm using it in the main living area and it has totally relieved the breathing, headaches, coughing and congestion issues I was experiencing from the residual nicotine remaining in our reno. Initially I was running it at high and now I just leave it a low speed. I highly recommend this product for anyone with similar issues.”
M. Shivrattan, Simcoe, ON

“The Austin Air HealthMate HM400 was an excellent choice for us and we are really pleased with our purchase. For years, my husband has woken up with blocked sinuses and nasal congestion. We use the air cleaner every night in our bedroom and he has noticed a huge improvement in his breathing. We keep the HealthMate on the low setting and are now accustomed to the white noise so that it doesn't bother us when sleeping. I also noticed that dust levels in the room are lower. I especially like the fact that we don't have to worry about changing the filter frequently.”
N. Clarke, Markham, ON

“Thank you for the email reminder to order a new filter for my Austin Air HealthMate, I can't believe that it has already been 5 years! I'm still extremely happy with my air purifier and I use it almost every day. It is terrific for a house with two dogs as it helps keep the air fresher and reduce the dander from them. Plus it helps with air quality in general as it makes such a difference on the days I have it running vs. the days I don't. I still recommend the Austin Air HealthMate as much as I did when I first got it!”
J. Batonyi, Calgary, AB

“I'm so happy that I bought the Austin Air HealthMate HM400 from you; I can highly recommend the product as well as Modern Alchemy Air Purifiers. Delivery was exactly as promised, and your customer service by telephone was excellent and so friendly. Within 24 hours we noticed the difference in the air. There are no more odours, we breathe deeper and better, plus the dust build-up around the apartment is pretty well non-existent now. The only little drawback I find is that the clean air the fan blows out is cool, which is great for the summer, but not in the winter when you are trying to keep your house warm. In conclusion, the Austin Air HealthMate does an excellent job at keeping the air clean.”
S. Bertholee, Niagara Falls, ON

“Just wanted to let you know that I picked up my Austin Air HealthMate HM-400 air purifier yesterday. After using it for less than 24 hours I'm very impressed! I slept very well and woke up feeling much less congested (just getting over a bad cold), and having the HM400 on the high setting for a few hours cleared out the smell in my apartment. I highly recommend Robert and Modern Alchemy for your air purifier needs, very knowledgeable and timely service.”
R. Patterson, Dartmouth, NS

** An Important Word on Air Flow Rates and Room Coverage for the Austin Air HealthMate HM400 Air Purifier:

Many retailers and manufacturers overstate maximum room coverage figures by calculating them with air flow rates measured without filters installed (i.e., fan output) or with too low a number of air exchanges per hour to properly clean the room. Modern Alchemy Air Purifiers believes in stating the actual delivered air flow rates for the air purifiers we sell, as well as realistic room coverage figures calculated at effective air cleaning levels. Accordingly, we recommend that the Austin Air HealthMate (HM400) be used in rooms of up to 235 sq. ft. (for premium cleaning) or 470 sq. ft. (for general purpose filtration).

Also note that air purifier performance should not be judged by air flow rates and room maximums alone. Many features that make an air purifier more effective at cleaning the air actually reduce the air flow rate. For example, higher grade HEPA filters, well-sealed filtration systems and large amounts of carbon all increase air resistance and reduce delivered air flow rates.
