I live in an area affected by active wildfires in Colorado. Air quality intermittently poor, occasionally very bad. I'm normally affected by airborne allergens such as dust & pollen. I can usually tolerate my fairly mild symptoms: itchy eyes, rhinitis, sinus congestion.etc. Since the smoke and ozone pollution exacerbated these symptoms, I bought the Medify MA-25 in order to create a 'clean' room. (My bedroom). After first night of use, I woke up with no sinus congestion for first time in years. I usually sleep w/ windows open, unless pollen levels are high. The MA-25 allowed me to keep windows closed (by eliminating room stuffiness) and proved that my allergies to even 'normal' air were worse than I thought. I'll be using it frequently even after wildfires abate. The unit has 3 fan speeds. The top speed is a bit noisy and I only use it when I'm out of the room. The middle speed is indeed 'whisper quiet'. Some white noise. No sleep disturbance. The lowest speed sounds as if unit isn't on at all. It's recommended to upsize purifiers for frequently occupied spaces so lower fan speeds can be used and still achieve proper purification. I highly recommend this well made, high performing, affordable purifier. It meets all requirements of CARB & Energy Star. Another plus: company is woman and veteran founded and is USA based though the unit is manufactured in China. I'll update review when it comes time to change the HEPA 13 filter. Read more
Very pleased with this air purifier. The set up was so easy and working it is very easy. I think the maintenance is going to be uncomplicated as well. It surpasses any of the purifiers that I’ve had in the past. Read more
I have bought several of these. Very few HEPA air purifiers are usable for extended time periods in normal conditions on the high setting due to the noise level. These are the quietist I have been around on the high setting (@53 dB rated by company confirmed with measurement in house using NIOSH app on phone). Still obtrusive, but you can have a conversation. Think somewhat loud dishwasher. Some others are about 10 dB louder but without providing more effectiveness. On the middle and lower settings they are nearly silent, although they don't move as much air, but good for small groups or small rooms - it would be nice if the company provided CADR data for the lower settings. These are excellent for bedrooms and small to medium living rooms and family rooms. They are lightweight and easy to move around so can be moved to rooms with an immediate need. We use them at home and in a classroom. I think they are a key reason why we have not had any transmission of Covid-19 in the house or classroom when an individual was known to be infected but nobody else caught it. OEM filters are expensive, but Fette and others provide after market filters at a substantial discount. In larger rooms, we use several of these instead of one large air purifier because you can clean zones of air in a room locally instead of drawing it to one central point and quickly reposition them in critical locations based on activities.

The Medify Air 25 is a great air filter. It is relatively easy to maintain: dust regularly, change filters when required or as recommended. My only suggestion for improvement that could extend the useful life of this air filter is to design the front of the air filter to have snap off / snap-on covers. This way all perforated areas can be maintained and kept clean and free of accumulated dust. As it is, the air filter is great is at factory fresh optimum performance for the first month. After that, the dust accumulation in the appliance seriously affects performance. If all parts of the filter can be maintained at factory fresh levels, then I would not have to put this in the waste stream. Replacing the filter every few months adds to the waste stream. And if I have to replace the appliance, then that also goes into the waste stream. Hopefully we can reduce the number of things that go into the waste stream with the purchase of this appliance to just the replalcleable filter cartridges. Thank you! Read more
My doctor recommended this Medify purifier for my small home office (about 500 square feet) to replace a larger one that I had for about five years. I'm a light pipe smoker and I keep my windows open when temps allow. I run it for about 6 to 8 hours a day, and it's far more effective than my last one (a more expensive big-name brand). It's quiet, powerful, and judging from the first electric bill, very energy-efficient. I removes tiny dust particles and mild tobacco odors better than I expected, and it also pulls in pet dander and tiny hairs that might float about. It's much smaller than my last one, so takes up little space. I vacuum vents about once a week and the filters are very easy to change. I'll likely by another one for the den. It's great!! Read more
I like that it has 2 filters on each side of it, and that it is small and does not take up a lot of room. On the low speed you can hardly even hear it, so quiet, on the high speed you can hear it, but if you are one of those people who needs sound to sleep, then the high speed fan could work for you. I love that it has a timer, for I have another air purifier on other side of house that doesn't and I always forget to turn it off. My other is a Biota bot and it has a color change feature that takes place when air quality is bad (red), back to purple then blue when air is clean. This Medify does not have that feature to let me know air quality BUT I ran the Medify in a room where the Biota bot always turned red, so after the Medify ran.. I brought the Biota bot in there to double check air quality and it did not turn red at all in any of the various different times and days I tried it. So the Medify is definitely purifying the air. Especially with covid I am so glad to have this Medify purifier with its higher grade hepa filters. Read more
