Austin Health Mate HM450+ Review
Top Rated Smoke Air Purifier

Not Willing to Settle for Anything Else Than Superb? Check This Out!

If you take the time to read all of the air purifier reviews I’ve posted on my website, you’ll find that I try to cover as much ground as possible. I have done this in the hope that your job finding an air purifier is much easier. Plus, I have taken into account that everyone’s needs and preferences are different, and when dealing with such subjective categories there are no absolutes.

Like you, I’ve found there are a myriad of different aspects to consider when you’re faced with choosing the most suitable air purifier for your home including types of filter, noise, performance, user friendliness and maintenance costs, (the list goes on).

Austin Air Purifier with 4-Stage Filtration

However, when it comes to actually buying the air purifier of your choosing there is generally one factor that does come into play, and that’s money. The Austin Health Mate HM450+ Black Air Purifier with 4-Stage Filter will appeal to just about anyone, but you’re going to need deep pockets in order to afford it. There is a very good reason for this and you’re about to find out why!

4-Stage Filtration

For me, the Austin Health Mate HM450+ began to justify its price tag as soon as I took a look at its impressive list of specs and outstanding filtering capability. Much like other models that have been issued by Austin, this one also features an impressive 4-stage filtration system. Featuring a total of 60 square feet of True Medical-Grade HEPA filters that are able to trap 99.97% of particles larger than 0.3 microns in diameter, and 95% of particles larger than 0.1 microns in diameter, the HM450+ meets even the strictest standards meaning it will remove most bacteria, viruses and allergens from the air.

The second component of the 4-Stage filtration system is the activated charcoal/zeolite layer which employs the principal of adsorption (not the same as absorption)! The 15-pounds carbon/zeolite component is extremely porous, and full of nooks and crannies which are able to trap even the smallest molecules such as gases and odors. Next are the two pre-filter components which capture large and medium-sized particles such as dust, bits of hair, pet dander, pollen, mold spores, dust mite debris and many others.


Apart from filtering, another area in which the Austin Health Mate HM450+ excels at is its high-powered performance. Standard size models are able to filter 70 to 400 cubic feet of air in a single minute, and 50 to 200 cubic feet of air per minute on junior size models. Needless to say, you’ll notice a change in the quality of air almost immediately. For example, at its most powerful setting which involves 4 air changes per hour, the HM450+ is able to filter all of the air inside a normal 465 square-foot home in under 20 minutes.


Similar to most air purifiers, this model also has three available settings: low, medium and high. The least powerful level is perfect if the purifier is located in your bedroom, and it’s so quiet you won’t even notice it’s there.

Even when you set it at high, the noise emitted by the fan still doesn’t exceed 66 decibels. This basically means it’s no louder than a normal speaking voice, making it perfect for use in heavily polluted areas. The build quality also plays a role since the Austin Health Mate is made out of 22-gauge steel. So, vibration or rattling won’t be an issue with this model!

Maintenance and Day-to-Day Use

One of the things I like most about this unit is you don’t have to pre-assemble it since the unit is ready for use straight out of the box. All you need to do us plug it in and away you go. The only control you have at your disposal is the dial which you use to select one of three fan speeds. I will give you one piece of advice though: since the unit emits clean air in all directions for optimal effectiveness, it should be placed at least 8 inches from the wall or any adjacent objects.

Since the HM450+ has permanent HEPA filters, replacing them should be done once every five years and it’s a process that shouldn’t take more than a couple of minutes. For every-day maintenance, keep in mind to vacuum the device so the grilles free from dust. I think you should also know this air purifier is available in 5 colors, and comes with a 5-year warranty for the mechanical parts, as well as the filters.

A Final Word

Personally, I believe the Austin Health Mate HM450+ is easily one of the best air purifiers money can buy. Its 4-stage filtration system is absolutely superb, the build quality is excellent, the device produces little to no noise, and there is no need for heavy-duty maintenance. Most importantly, its performance is suitable for just about any home and will meet the requirement of even the most demanding users.

Sure, it will cost you more than most other models on the market but honestly, it’s worth every penny. If you are interested in buying one for your home, take the time to visit Amazon which always has some great deals on domestic appliances and consumer electronics such as air purifiers.
