The starters

Austin Air HealthMate Plus weight
47 lb (21.3 kg)

First off, Austin Air HealthMate Plus shares Austin Air standard air purifier platform design and dimension at 14.5 x 23 x 14.5 in. Its considerably bulky though not too tall, the only complains we had with Austin Air HealthMate Plus is its hefty 47 lb weight that is largely contributed by the premium powder-coated steel housing. Thankfully the 4 wheel casters come in handy when you need to move the air purifier around. On to the usability, Austin Air HealthMate Plus is super-easy to use as there is only 1 front dial knob to control the air purifier. While the lack of air quality sensor, auto mode, filter indicator is a big bummer, other notable specification includes excellent 4-stage filtration, 5 years all-in-one filter lifespan, 360° progressive Intake System, NRTL (Nationally Recognized Testing Laboratory) recognized, CSA (Canadian Standards Association) and CE (Conformité Européenne) approved, no ozone emitted, 30 days money-back guarantee and 5 years warranty on residential use.

What’s inside count

With only one notable difference between HealthMate, Austin Air HealthMate Plus 4-stage filtration is great against large to micron-size particles that you expect no less from Austin Air. The first stage of defense is the outer mesh grille plus bundled pre-filter that captures large particles such as dust, hair. The continuing second stage is the medium particle filter that would follow up on smaller size particles that were not captured by the earlier pre-filter. On gases and odors related particles, Austin Air HealthMate Plus enhanced 15 lbs. of carbon impregnated with potassium iodide would do a great job against chemicals typically formaldehyde and ammonia. The last-stage HEPA filter would concentrate on micron-sized particles that were not captured previously.

Keep it down

Austin Air HealthMate Plus power consumption
Power consumption
132 W
132 W average power consumption is high but not too far off from same segment air purifier. As with all Austin Air purifiers, Austin Air HealthMate Plus 40 - 65 dB is considerably loud even at the lowest speed. The classic "place the air purifier far far away" could be used to alleviate from the noise. With that being said, Jr version would be more suitable for bedroom use.

^ Replacement filters/ estimated cost
Austin Air HealthMate Plus premium asking price might not be reasonable given the lack of modern practical features, it's still a sturdy, well-built air purifier with genuine filtration capabilities. What you will get in-return is one of the lowest annual filter replacement cost thanks to long-life all-in-one filter that could last up to 5 years. Another mandatory thing we need to mention is the not so straightforward filter replacement process that requires unscrewing in order to remove the cover rather than slide-out mechanism.
We seen huge discount (around 30-40%) for the White version on Amazon. Not so much on the Black version but it's there. You can purchase of Coway AP-1512HH Mighty air purifier on the official website, Walmart, Target, BestBuy, HomeDepot, Lowe's, or Costco but our pick has to be Amazon as it has low/ free shipping, best online deal, and hassle-free return if you are not completely satisfied.
