"Its true HEPA filter grabs fur and dander"
"Best air filter we have ever owned. ... We have 4 of them in a 4000+ square for house where we foster cats (10+ at any time,) and the amount of fur, dust, and general particles it filters out is amazing. ... Friends who are severely allergic to cats come over with zero issues with these filters running."
"It wasn't until I upgraded to 2 winix machines that I finally got relief and it was instant."

"I have 4 of them - 1 in each bedroom, 1 in entryway/dining, 1 in living room - all running for ... 7-8? years solid, 24/7. ... I went with a bunch of Honeywell HPA300 machines to cover multiple rooms several years ago and have been thrilled. They run 24/7 every day on low"
"This Honeywell HPA300 is a beast for allergies. ... I’ve used it in my living room, and it noticeably reduced my sneezing and stuffy nose during allergy season."
"I too have a stinky cat and a rabbit who doesn't stink but sheds like you cant believe. I went totally overboard and got SIX of these for 2100 sq ft place and my air has never been cleaner. ... If you get 3, your air will be pure."

"The medify that we have has a super low speed setting which means we can sleep with it next to us and get a nice breeze of purified air while the machine says silent."
"I definitely agree with others who have said to get a “size up” from what you think you need for your room size, so you can run it at a lower level and have it be quieter."
"You can also control the speed and the sound with more nuance than most commercial units"

"the filter costs have you replacing filters every 3 or 4 months with full use."
"so are Coway and Blue Air when you add up the cumulative price of filters. ... And, I find I need filter replacements much more often than recommended further increasing the cost."
"The pre-filter is insufficient and the HEPA filter gets dirtier much faster."

"the medify one sounds horrible- it has a weird high pitch and i can’t stand it even on the very lowest setting. ... i actually sent it back and they replaced it and the second one sounds the same."
"We have 2 levoits and even on 1 I can hear it across the room with the TV on. ... They both have an ear-piercing high pitched sound that I can't stand."

"I had a medify one and returned it because the AQI inside my apartment was 150 after running the purifier 24/7 for an entire week. ... I shut all my windows and doors and turned my Medify air filter on full. I was then sick for an entire week. Got an air monitor, saw the AQI was at 150."
"The vitals barely reduced PM when I used them."
I have two dogs in a townhome and have 3 air purifiers. Absolutely love them. No dog smell. I have one Medify and two Levoit. Just make sure you get one that can actually clean the size of the space it will be in. The downside is buying the filters, but I find it worth the cost, and you can find cheaper, off-brand filters on Amazon.
r/dogs • Air purifier for dog smell ->medify needs more love. those medical grade H13 filters are legit
r/AirQuality • I analyzed 60+ Reddit threads to find the best air purifiers ->I've enjoyed Medify MA-50s.
r/BuyItForLife • The REAL best air purifier - I HATE DUST! ->I bought 5 Vital (100 + 200) devices and 1 Core. The vitals barely reduced PM when I used them. I switched to Coway and Medify and had much better results.
r/AirPurifiers • is Levoit Vital 100s the best air-purifier? ->I've been using Medify Air for 5+ years and they've held up well. They work well, especially during wildfire season. I also run them when guests are present to reduce the spread of airborne germs for an immune compromised household member.
r/BuyItForLife • The Best Air Purifier for Home now? Have you noticed a huge difference since you started using them? ->I own medify air. I cannot complain about performance. However, people online complain that you must change your filters every 6 months or your lifetime warranty will be voided.
r/BuyItForLife • The Best Air Purifiers? ->We use medify air purifiers
r/homeowners • To kind homeowners, the best air purifier? What do you use for home? ->I’m in the same boat. Wondering what decision you made? I had a medify one and returned it because the AQI inside my apartment was 150 after running the purifier 24/7 for an entire week. I then got a Wellis and I’m doubting its efficacy just cuz I’m like wtf is this technology and I see basically no reviews online. I’m leaning toward air doctor I think? How about you?
r/AirPurifiers • Air Doctor, Winix, Coway, Levoit, Wellis Air ->We bought a Medify MA50 about 2 years ago, and the dust and pollen collection is outstanding. I thought that I would have to buy 2, but 1 is adequate for our home.
r/homeowners • What's the best air purifier for home you swear is really worth buying today? ->We bought a Medify MA50 and it has really helped with the pollen and our dark hardwood floors are a lot less dusty.
r/homeowners • The Best Air Purifier for Home to Buy now? Do you find the air in your house actually better since you started using it? ->tbh they're all basically the same. just get whatever's on sale at costco that has a hepa filter. i got some random medify one for $150 and it works fine. people overthink this stuff way too much lol
