Medify MA-112 Air Purifier with True HEPA H13 Filter | 2,640 ft² Coverage in 1hr for Smoke, Wildfires, Odors, Pollen, Pets | Removal to 0.1 Microns | White, 1-Pack

The Medify Air Purifier has been one of the best investments I’ve made for my health and workspace. It’s not just an air purifier—it’s a total air-quality game-changer! From the moment I set it up, I could feel the difference in the air. It’s cleaner, fresher, and far more pleasant to breathe, no matter what activity I’m doing.One of the standout features for me is how effective it is at handling specific air quality challenges. I run a 3D printer print farm in my workspace, which can produce noticeable fumes and fine particles. This purifier tackles those head-on, eliminating odors and filtering out even the tiniest particles from materials like PLA and ABS. It’s a lifesaver for anyone who uses a 3D printer, but it doesn’t stop there. Whether it’s dust, pet dander, pollen, or even cooking odors, the Medify takes care of it all effortlessly.What truly sets this air purifier apart is its combination of power and quiet operation. Even on higher fan speeds, it’s whisper-quiet—so much so that I can run it while working, having conversations, or even sleeping without it being a distraction. The sleek and modern design is another plus. It blends seamlessly into any room without taking up too much space, and it’s surprisingly easy to move from one area to another if needed.The user-friendly features make it even better. The touch controls are intuitive, the timer function is a thoughtful touch, and the filter replacement indicator removes any guesswork from maintenance. I’ve also found that the filters last longer than I expected, which adds to its overall value.Since I started using the Medify, I’ve noticed a dramatic improvement in how I feel—fewer allergy symptoms, less irritation from airborne particles, and an overall fresher environment. It’s not just an air purifier; it’s a way to create a healthier and more comfortable space, whether it’s a home, office, or workshop.I can’t recommend this air purifier enough. If you’re on the fence, don’t hesitate—it’s worth every penny. Whether you’re dealing with allergies, odors, or specific challenges like 3D printer fumes, the Medify Air Purifier will exceed your expectations. This is hands-down the best air purifier I’ve ever owned!

It so happened that when we were called to return to corporate offices to work, we wanted to get a large air filter that could be wheeled into conference rooms as needed. We found this air filter at a discount on an Amazon warehouse deal and saw it was large and had wheels. We took the chance.Pros & ConsPROS1. Fairly quiet for an individual office or conference room at the level 2 setting, like a low fan that's audible but not intrusive. (Level 3 is significantly louder.) Level 4 is max.2. Wheels! Good for short distances on low-pile carpet or hard floors, but the wheels are small so wouldn't recommend for rough surfaces like sidewalks for more than a few seconds.3. The intake is on two sides, and the output shoots upward. This is great so that we can pretty much place it anywhere in a room and not worry about blasting someone with cold air.NEUTRAL4. It's quite big, barely fitting under a desk for storage. (It didn't fit under ours.)5. Our unit turns off automatically if it's left in the dark. We researched and found that version 1 of the MA-112 used to have an "AUTO / Child Lock" button and that when the unit was powered on, it started off in AUTO mode until the fan speed is pressed. By the time version 2 came around, Medify stated they removed the AUTO mode button. However, our experience has been that whenever the lights turn off in our rooms, the MA-112 also goes to sleep after a few minutes. In a modern office setting where the office or conference lights are motion activated and will dim/turn off if no movement is detected, our MA-112 seems to always be in AUTO mode and does stay on as long as the lights are on, and then goes to sleep after 3-4 minutes if the lights go dim.Of all the buyers of this device, there probably couldn't be a better match for a malfunctioning air filter. We actually do need the air filter to turn off automatically if the room is empty and the lights go dim. However, there's no way to turn this off, and so if we ever give the air filter to someone for home use, it will be impossible to keep the unit on all night.Update 3 months later:I'm embarrassed and relieved to update that the auto shut off wasn't broken. We discovered that the outlet we connected it to in the office powered off according to the motion sensors regulating the lights. Once we swapped out to a different outlet, we no longer had the issue of the purifier turning off when the overhead lights went out. I updated the rating to 5 stars now.Also, still love the little wheels to help roll it around the office to conference rooms.
