The Austin Air HealthMate Plus (HM450) air purifier offers all the benefits of the Austin Air HealthMate, but uses a special activated carbon blend that is impregnated with potassium iodide to more effectively remove hazardous or chemically-reactive gases. The Austin Air HealthMate Plus provides the ultimate protection for people who are sensitive to formaldehyde, ammonia and other harmful chemical vapours produced by common household cleaning products, detergents, indoor pesticides, paints, furniture, carpets, drapery, office equipment, etc. This air purifier is also an ideal choice to protect new home owners against volatile organic compounds (VOCs) and off-gassing from building materials, new flooring and cabinetry, and paints/varnishes/sealants. In addition to superior gas filtration, the Austin Air HealthMate Plus also offers excellent odour and particle control (e.g., for pollen, dust, mould spores, pet dander, combustion pollutants) and is designed for use in medium-sized rooms.

The Austin Air HealthMate Plus features a Permafilt pre-filter that is designed to be easily vacuumed from the outside, making this air purifier simple to maintain and eliminating costly 3-month pre-filter changes. The Austin Air HealthMate Plus uses a combined medical-grade HEPA and 15 lb. activated carbon/zeolite/potassium iodide blend 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 Plus air purifier is perfect for living or family rooms, large bedrooms, bachelor apartments or any mid-size space where chemical fumes are a concern (e.g., workshops, hobby rooms, artist studios). With a baked-on powder-coated finish and four colours to choose from, the Austin Air HealthMate Plus blends easily into almost any décor.

“Amazing, simply first class all the way, thanks so much! Purchasing the Austin Air HealthMate Plus HM450 air purifier is one of the best decisions I’ve ever made according to my partner. She cannot stop talking about the unit and I am the one with the COPD. The difference for me is like night and day. So thanks and all our filter needs will be purchased through Modern Alchemy. For the record, it took me over a year of research to find Modern Alchemy Air Purifiers and Austin Air. So thanks once again from both of us.”
Martin M., Vancouver, BC

“I have been conscious about my family’s health, particularly my son who is very susceptible to allergies and respiratory concerns. I have always wanted to invest in a decent air purifier (not the commercialized ones we usually find on the market), and have searched the net to compare prices and study reviews. I ordered an Austin Air HealthMate Plus air purifier from your company and I have really felt the difference. It felt like entering an air conditioned room during the warmest part of summer. I felt refreshed. According to my son, his habit of blowing his nose, coughing and sneezing has also decreased. We were also surprised that the Austin Air HealthMate Plus actually removed the odour produced by frying fish in 5-10 minutes. I am ordering a second Austin Air this week because it really works.”
R. Suva, Winnipeg, MB

“I purchased the Austin Air HealthMate Plus HM450 after several months of trying to deal with the smell and off-gassing produced by new carpets in our office. I had tried everything - many fans running on high all night, steam cleaning and vacuuming the carpets, and several hundred dollars worth of plants. Nothing was really helping until I bought this air purifier. Within two days the carpet smell seemed to have completely disappeared and everyone in the office has been feeling much better. The Austin Air HealthMate Plus has made a huge difference to the overall health and well-being of my colleagues, as well as our general productivity. It was money well spent and I recommend the folks at Modern Alchemy very highly.”
J. Manning, Vancouver, BC

“I just wanted to let you know that the Austin Air Healthmate Plus air purifier that I purchased from you is working great and your suggestion was right on! I had an issue with cigarette smoke filtering into my apartment from neighboring units and from outside, and generally poor ventilation and indoor air quality in my bachelors unit because of the building structure. The HealthMate Plus seems to be much more effective for this purpose given its large carbon/activated charcoal filter, and it also has the HEPA filter which makes it a full-suite air purifier. My Coway Airmega is good as well, but not as good for this particular purpose, because a much larger charcoal filter is required for smoke VOCs (at least 5 pounds), which the Austin does have. I’m very happy with my purchase, however, I would definitely run everything by Robert of Modern Alchemy Air Purifiers before making an investment.”
D. N., Ottawa, ON

“We have been using the Austin Air HealthMate Plus air purifier since February 2014, it has been a great unit. We have a wood stove and before we got the Austin Air, I was dusting daily, but since we started it up I have gone days, if not weeks, without the need to dust. The HealthMate Plus is a bit noisy, but we just turn off the air purifier if we need silence and make sure it is running at all other times. I am an allergy sufferer, and this year the pollen is especially bad. We put the HealthMate Plus in the bedroom for a day and I was amazed at how well the air cleared. However it is too noisy for us to keep in the bedroom so we have ordered a Blueair unit and will let you know how it works. I would definitely recommend Modern Alchemy Air Purifiers, Robert was very helpful and their service has been excellent.”
K. Olson, Beasley, BC

“We are really enjoying our Austin Air HealthMate Plus air purifier, and have noticed a real difference in our allergies.”
E. Smyth, Grande Prairie, AB

“I absolutely love the Austin Air HealthMate Plus air purifier I purchased from you. I have severe Multiple Chemical Sensitivities, and have had to return a few air purifiers in the past due to this. When used in my bedroom, the Austin Air HealthMate Plus helps me to sleep without being stuffed up during the night and when I wake up in the mornings. Unfortunately, I found the unit didn’t do as well in my kitchen, living room and dining room area, because of the recent painting and the size of the area. I would totally recommend your company and the Austin Air HealthMate Plus. I felt you were very knowledgeable, understanding and explained your products really well, and also had solid advice regarding which units you felt would be best suited for me.”
C. Friesen, Steinbach, MB

“Just wanted to let you know that we love our Austin Air HealthMate Plus. It keeps our home smelling fresh and reduces the allergens and toxins in the air. Modern Alchemy has the best prices, but more importantly, Robert is extremely knowledgeable and honest with his advice. He is constantly learning and will always offer his genuine opinion on all questions regarding health matters. I recommend all friends and family to Modern Alchemy.”
Z. Kassam, Vancouver BC

“Our two Austin Air HealthMate Plus air purifiers work great at removing the toxic odours in our house, and my husband doesn’t have such a stuffed nose anymore!”
A. Reichert, Eatonia, SK

“I am very impressed with the Austin Air Healthmate Plus air purifier you sold me. It does a great job, and I love it very, very much.”
N. Occhionero, Montreal, QC

“My husband and I knew we wanted to get an air purifier, but had no idea which one. My sister has the Austin Air Pet Machine, but the store she bought it from was no longer open. I stumbled across Modern Alchemy Air Purifiers' website and was thrilled to see they had a summer sale on! When I called (many times), Robert was incredibly knowledgeable and patient. He explained everything in great detail, so I had a clear understanding of the benefits and differences between each Austin Air model.

We decided to go with the Austin Air HealthMate Plus HM450. We rent a newly built apartment and have two dogs, and even though we've only owned the machine for under a month, we have already noticed a difference! I don't notice the dog smell anymore, and it helps to quickly remove cooking smells as well.

I have to say that the biggest benefit is my improved sleep. Previously, we slept with the fan on, which I hated because the air blew directly on me, but the HealthMate Plus gave us the same benefits of air circulation without just blowing dust around. I have also grown to love the white noise in the background. We are comfortable leaving it on either level 2 or 3 overnight. Since our home is one level, I can easily move the Austin Air unit from the main living space during the day to our bedroom for the evening.

We are very happy with this purchase, and if we need another air purifier in the future, we will definitely be returning to Modern Alchemy to buy it.”
Tristan E., Regina, SK

** An Important Word on Air Flow Rates and Room Coverage for the Austin Air HealthMate Plus 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 Plus be used in rooms of up to 235 sq. ft. (for those with chemical sensitivities) 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.
