Medify MA-35 Air Purifier with True HEPA H13 Filter | 1,280 ft² Coverage in 1hr for Allergens, Smoke, Wildfires, Odors, Pollen, Pet Dander | Removal to 0.1 Microns | Silver, 1-Pack

We needed an air filter in our upstairs hallway. This tucked in nicely in the small section of wall that had an outlet (small enough that the unit overlapped the trim on the adjacent doors a bit, which worked fine because of the way this unit mounts to the wall). I love that it’s off the floor, which makes cleaning much easier. There are no cords on the ground for people to trip on and it’s mounted high enough to clear the footplate of my wheelchair so I don’t have to worry about hitting it when I turn around. We have it set on automatic most of the time, and the air sensor does seem to work. The air quality is noticeably better than before. I wish the filters were less expensive, and that there was a separate carbon prefilter. It’s more expensive to run it than similar units that sit on the floor. Still, if you need something that mounts on the wall, the higher price is worth it, in my opinion.

First things first - if you're like me and were looking for a low profile, wall mounted air purifier, this is just about your only option on the market today. There is the RabbitAir MinusA2, but at nearly $600 it's in a price point that discourages most. That's what lead me to purchase 3 of these, and unfortunately what lead to my disappointment and one star review. Let's talk about the good: * Design is good - not great - but the unique wall mount does genuinely save space and looks good while doing it. The mounting system could have been much better than the odd 3 point screw mount but it does what it needs to. * Air monitor seems to work and the auto mode kicks up reliably when smoke from cooking starts to make its way over. Now the bad: * Design flaws - as noted in numerous other reviews, these units develop a buzzing sound in the top corner even while the unit is completely off. It's loud enough to disturb sleep and inexplicable given that it is not coming from the fan, I suspect defective internal power supplies may be to blame. * Replacement media is expensive and Medify does not enjoy the large variety of aftermarket replacements that bigger brands have. * The remotes are all on the same channel and seemingly have great range, which would be a plus if you don't have multiple units - if you do, you'll find that turning one off will turn all the others off by accident. * They do not stand behind their products - after one of my three units developed the buzzing noise, I submitted a warranty request given their lifetime warranty, I hoped they would make things right - these are not cheap and when paying for a premium product I presume that part of that cost is to ensure a high level of support. Unfortunately, all they do is look for a way to avoid standing behind their product - the issue I had has nothing to do with filter media (it happens when the damn thing is completely turned off but plugged in...) but they still insist documentation of all filter purchases and will only honor the warranty if they are from Medify directly. That wasn't a problem for me given the lack of aftermarket options, but a harbinger of what was to come. My issue was that the specific unit in question was purchased open box from Amazon warehouse (and worked perfectly for 6 months, so it had nothing to do with how it was sold or a factory defect) and they outright rejected any claims because of that. Never mind that I could have submitted the receipt from one of the units I purchased new, I conduct my business honestly and can't fathom what difference that makes given it was sold new by the authorized retailer (Amazon), returned new in box and was sold again, by Amazon. If you must purchase one of these, whatever you do, do not buy on Amazon warehouse, used from another source or new from a retailer that is not Medify themselves because it will eventually fail and they will not honor their warranty.

This model is so good after one year of use in my bedroom that I am about to buy a second one for my office. I had a smaller unit in my office that I was unhappy with and now that the filter has reached it's end of life, I'm going to replace the whole unit with another one of these. Trust me, spending the extra money on the ability to hand this on your wall makes a huge difference. I have a Medify floor unit in my large main room that works great (The MA-112). The floor units are very good at catching cross traffic as you or your pets walk by it and stir things up. The wall units are great at catching that ambient "air garbage" that circulates while you are not moving like sitting in a chair at your desk or sleeping. Also, if you have a window nearby, the heat coming in from the sun will also cause more circulation of particles as the heat changes the air flow and brings things up from near the floor more towards the ceiling. If you can, have both and strategically place them. This wall unit is so good I think it's worth the extra money to be able to hang it. I hope this helps.
