Austin Air HealthMate Plus Air Purifier White - Advanced 4- Stage Filtration Air Purifiers For Home with Activated Carbon & Zeolite - Ideal as Air Purifiers for Bedroom or any Large room, Model B450

Had it a year and it is awesome. We leave it on the highest setting in the moring come home no smells. Its cleaning 5 rooms. The highest fan speed its loud but use thay as a sound machine at night. Im not sure it will last 5 years. I think my sons fish cooking every week has killed the filter. How do you know when to change the filter

This unit has worked very well initially. Replacement filters are expensive but very reasonable if in fact the filters last 5 years. It will be awhile before we find out if this is true.

Does its job. Spouse is breathing better since introducing it into our household. Cant even hear it on the lowest setting. Highest setting is pretty loud. Maybe comparable to a light/small vacuum sound. House doesnt have lingering cooking smells after meal time. Will be purchasing a second one.

I have a nice apartment, and my neighbor has a heavy pot smoking habit. This machine (cranked on high) will remove 90% + of pot smell leeching into my space. In my case, the smoke smell was seeping through the wall that divides our units. My neighbor does not share any ventilation ducts with me and is completely walled off. I tried (2) other Levoit air purifiers (300 and 400) before landing on this one. They were a joke and did not remove the smell. This unit, the Austin Healthmate Plus with 15lbs of activated carbon, actually works. I stuck it in the corner where the smell seeps in, and leave it on low or medium all the time. The unit is a bit loud on high, and the fan seems to "flutter" a bit on low/medium. If you are buying this, you care more about clean air than you do a very slight flutter in the acoustics. You are paying for the commercial quality air filter. This unit is powerful enough to clean all the air in my 1200 square foot space on medium. There is a noticeably neutral smell throughout the apartment if I leave it on high. When my neighbor is actively smoking and the machine is on medium, I can smell something slight. I then turn the machine on high and the smell goes away. If I turn the machine off I can start to smell it again within 5 minutes, so I know it works. I think this is the best tool to regain control of your air if you are struggling with a neighbor's smoke. Before I got this I was coughing/sneezing, and it was psychologically distressing since my bedroom is where the problem originates. Completely worth it in my opinion. Also, apparently the relative humidity in your space should not exceed 60%. Excess moisture will react with the potassium iodide impregnated carbon filter, and that will apparently reduce its life. Only the Healthmate PLUS has potassium iodide in the filter. I don't know how well this machine would handle direct smoke in the same space. Anyway, now I don't have to move, and I can think about something else besides what my neighbor is smoking.

Love this! I baught 2. One for my bedroom and one for my living room. They are really helping with the new furniture off gassing. I still had to get rid of my bed frame because it was MDF and pressboard and my face was right by the headboard all night. The filter could not filter the air between the head board and my face between each inhale. Although, a fan might have helped if I could have tolerated the wind on my face. Regardless, this filter is great for the MDF electric fireplace (since I don't put my face against that one), new sofa, new area rug , and new accent chairs (all in the living room), oh and new kitchen table and chairs and my new to me used MDF and pressboard desk located in my bedroom. Suggestion: Don't sell everything and start over. Just beg you mom for all of your grandmothers furnature (live and learn). But, these filters are a life saver! On high they are a bit loud. So after the initial air clearing phase, we now turn them down when we are in the room. We turn them on high when we are not using the room (eg living room when sleeping and bedroom when awake) and every time we leave the house. (FYI, before all of this new Furnature, I did not know about chemical sensativity. So, you might be more sensative than I. Still these are great for the appropriately sized room.)

I am only giving it 4 stars because I need more time. Have had it about a week - not sure it deserves 5 stars yet. House while I live in it - is under construction. Have some Allen Breathsmarts 45i and they have done fairly well. But after adding the Healthmate while under construction with the current breathsmarts - I feel like I am breathing hospital air - Healthmate made a big difference. On the lowest setting, barely noticeable sound (you will hear it a little). Once you go to 2 or 3, it definitely creates a whooshing sound. I would think the lowest setting is fine for most situations UNLESS you have active wild fire around you or like me living in a house under construction. If you live in an apartment, the lowest setting is fine. Obviously you need to fit to size your needs and the quality of air it must clean. Breathsmarts self adjust if pollution is detected, Healthmate is old school analog setting (speed 1,2,3). I am not sure if I was living through construction the Healthmate is something I need. But I also spend time in a place with FREQUENT wildfires, this thing would be perfect. Healthmate certainly seems to live up to its reputation, you can hear it, but it sure does clean the air. 15lbs of active carbon and a few other tricks to clean up vocs, seems to be working quite well. If you need next level clean air, probably a good choice, worked well for me. Regardless of the marketing hype from other companies, if you want to suck air through 15lbs of active carbon and an air filter you are going to hear something. That is simple reality. If 15lbs of carbon is spread across a 6' unit, it would be whisper quite, but who wants a giant machine in the house.

They are a bit pricey, but I bought this to deal with 3D printing in my office (along with an air quality monitor). The monitor has only gone off once, so I started up the filter, and a few minutes later, it was all clear. Then I started running it on medium all the time and noticed my stuffy nose cleared up, so it is obviously doing some good work. It is pretty loud running on high, but it is actually the volume of airflow, not the fan that I hear.

I moved to a rental end unit townhouse because of my condo (which I still own) having nuisance second-hand smoke from a renter. Well, I purchased this air purifier because the rental unit, while smoke-free initially, started to have tobacco smoke coming into it about two weeks ago. Other air purifiers which I bought here on Amazon helped mitigate the smoke after the next-door smoking has ceased but not keeping up with it while the smoke is coming through the townhouse walls. "Gemini" and "ChatGPT" AIs both steered me towards this product citing the activated charcoal volume and chemical additives. But, as I write, while this "Austin Air HealthMate Plus Purifier" is running behind me on full speed, the new cigarette smoke smell, I can clearly smell. With tax this cost me about $906 US dollars. I wonder if they will let me return it. It does not seem to be able to keep up with the smell. It arrived on time without damage. It is heavy. But I managed to move it a stair or two at a time up to my second floor level living area. Frankly, my lesser quantity activated charcoal filter air purifiers seemed about the same with managing the incoming smoke smell. To say that I am disappointed is to put it mildly. Perhaps the company can rectify this.

Extremely loud. There’s no way any can realistically use this in a modern apartment.
