Austin AirHealthmate Plus - Powerful Air Purifier with Medical-Grade Filtration System, Eliminate Harmful Airborne Contaminants, (Black), Model B450

it actually works against pot smoke. Tried many machines that did not work. This is the only one that worked

WORKS LIKE A CHARM. MY ROOMS PM2.5 WENT FROM 50PPM TO 6PPM. GRAND! WELL WORTH THE INVESTMENTS.

I love this purifier it pulls so much junk out of the air. I have severe allergies and chemical sensitivities and have one at work so I already knew they work well. However, I bought this when there was a wildfire in my neighborhood and I ran it on high for about an hour and it pulled all of the smoke smell out of my house.

This product made me ill. the company said a percentage of customers can not tolerate the filter's ingredients. I will say this, it sure removed the chemical smells in my apartment.

Why did you pick this product vs others?:Recommended by our long term HVAC rep. Ordered and received it quickly. The unit seems to work great, we're very happy with it. Glad to get exactly what our guy recommended.

Initial subjective impressions -- does a great job at scrubbing dust and allergens from the air. Squeaky clean. Jury’s still out on odors, can’t tell yet either way. To that end…. Pros: 1) Heavy-duty, all powder-coated steel construction. 2) Simple design. It’s got a simple mechanical switch for speed control, and a ball-bearing motor driving the impeller. 3) The filter canisters are BEEFY, also fully steel construction, with a serious gasket sealing both ends of the barrel. 4) Outside of the generous warranty period, Austin Air will repair any of their units for a $90 flat rate. 5) While the pre-filter is replaceable separately, when any part of the multi-stage filter can becomes saturated — the whole assembly needs replacing, which is fine. Austin does offer a pro-rated discount on filter replacements, so it’s hard to complain about that. 6) No stupid app, WiFi or "smart" features! It's an air-cleaner, and that's it! 7) Made in the USA. Cons: 1) Price. Despite building these with US labor, it’s hard to see how such a simple machine costs quite so much, but I digress. 2) Size. These things are about the size of a tall mini-fridge. 3) Quite loud on any setting other than low. 4) Power hungry. Final thought — it’s my understanding Austin Air has been building effectively this same machine for decades now, with only minor enhancements to the filter media package. Advancements in motor efficiency, and turbine /fan blade tech have come a long way since then. These units could easily be made quieter, and to use less power. It would be nice if Austin were to not only roll upgrades into new-build air purifiers, but offer existing owners an upgrade program as well.

These are great, and very quiet, even at high speed. I bought a large one for my living room, and two smaller ones for bedrooms. They all work well. Don't buy the electronic ones. They're not safe.

I have a dog and my roommate has a cat. We didn't want the first thing for guests to notice when they walk into our home to be the inevitable pet smell. Even if animals are bathed, there is always a smell. This keeps our home smelling clean. Also, before purchasing this product, I would frequently wake up in the middle of the night with a stuffy nose. I now sleep through the night without a problem. This purifier is definitely worth the price. My only complaint is that I wish there were an indicator for when the filter should be replaced.
