Medify MA-25 Air Purifier with True HEPA H13 Filter | 825 ft² Coverage in 1hr for Allergens, Smoke, Wildfires, Odors, Pollen, Pet Dander | Removal to 0.1 Microns | White, 1-Pack

It works well, removes dust and smell efficiently. It's quiet in low and medium mode. Its noisy at high mode, but I only need to keep at that level for few minutes when cooking something that smells or smokes. The timer works well, although the 4-hour timer light failed after a year in my device.The filter lasts for at least 1 year, which is good enough considering the device is in the kitchen, where grease can clog the filter (but I don't fry food at home, so not much grease).The only issue that one might have is that the air is pushed out straight to the front of the device, but I'd prefer to be able to change the airflow direction up. I improvised by tilting the device up a bit.

I bought this thinking that it would do very little in terms of scrubbing the air for dust and debris. I had read some reviews stating that it didn't do anything for them, and that it was not as good as X or Y product. This has not been my experience at all. I have owned this for over a year now, and it collects MASSIVE amounts of dust that I didn't even know existed. At the first filter replacement interval, I wiped the surface of the filter media, just out of curiosity to see how much dust it had actually accumulated. I was genuinely horrified and relieved at the same time when I saw the results. Horrified because the sheer amount of dust this unit collected on the filters was staggering. I didn't even know the air could be so dirty. I was relieved though because all that dust was now on these filters and not in my lungs. I can definitely say that my lungs have felt better, and I can breathe easier at night since I've purchased this unit. For reference, I run it at max speed throughout the day, every day, when I'm not in the room. Then I turn it down to the lowest setting and leave it running while I sleep. The noise is barely noticeable on the lowest setting, and it's placed within 3 feet of my ears.My only complaints are that #1 the filter replacements are quite expensive, but I guess it's fair since it actually is doing what they claim, and #2 when I bought this, it was about $200 for the single unit, and now I see that they have a 2-for-1 deal going on for these. I would have preferred to buy the 2-for-1 back then instead of the single. I'm honestly really happy that I bought this one, and I wouldn't hesitate to buy it again if I needed to.

We have 3 of these— two of the largest size (M50 I think): 1 for the main floor of the house and 1 for the walkout level, and this smaller size for the master bedroom. Have cut down greatly on dust and improved overall air quality in our home. We change each filter every 6 months; no issues with allergies (even though the manufacturer says to change the filters every 4 months…). The older units are 3, and 5 years old still look/work like new.

This is a good air filter.I'd purchased one for my bedroom, and even running at the low setting, it noticeably cleans the air. There are a few quirks that could have been done better, but rather than trying a different filter (and needing to buy two different sets of replacement filter elements) I'd bought a second one for my living room.The good: It's quiet, it's easy to use, it's lightweight, the visual design is pretty, and it fits in my space – almost.The quirks:The power cord plugs in the back, which means that the unit can't be placed next to a wall. It has to be about 2 inches away from the wall. The sides and the front can't go next to a wall either because that's where the air vents are.The control panel is on the top. There is space on the front where the control panel could go, but it's on the top. Unfortunately, this means that you can't put anything on top of the unit. It's the perfect size to put down a book you're reading on, but you can't. Also, good luck explaining to your cat or bird that they cannot perch on top of the unit..The indicators are integral to the control buttons, not adjacent to them, this means that you cannot blackout the indicator lights with black tape without interfering with the controls. There is a button to dim the controls, but that button also glows, but it is significantly dimmer than the other buttons. However, if the unit is off, the power button flashes, and the dim functionality does not work.In my bedroom I find the dim function sufficiently dim, and the fan quiet enough to sleep nearby, but if I want to turn it off when sleeping, I need to unplug the cord to turn of the flashing power button, and that's annoying.But again, it's a good air filter, and despite the quirks, it's good enough for me to buy a second one.

Great product!Quiet and efficient.

We’ve had ours for four years. They work great.
