Medify Air - MA-112 UV

Roborock vacuum running on a schedule and a Medify (hospital-grade) purifier.

Hey man. I currently own (1) MA-112 in my master bedroom, (2) MA-40’s in the guest bedrooms, and was waiting on the MA-125’s to go on sale again as I want two for the living room. I am a Steamfitter that has done some HVAC and became interested in IAQ. After unfortunately coming across and dealing with some mold in A-coils / ductwork in the places I was staying at, I wanted to find a solution. While I was staying at an AirBNB long term, I AGAIN had respiratory issues and narrowed it down to what I believe was contamination somewhere in the supply ductwork. I’ve yet to order a particle counter to quantify things moving forward… But nonetheless, while in that AirBNB master bedroom, I ordered and setup a MA-112. I calculated the rough cubic footage of the space and used setting 2 and 3 on the MA-112 for ~6-10 Air changes per hour. I blocked the supply vent and kept the purifier on. —> Me and my partner after a week noticed major reductions in our symptoms. They definitely work for lowering particle counts. Now. The only drawback that I know of with these units, other than cost, is the carbon filter is in FRONT of the HEPA. I wish it wasn’t. Something to be mindful of. I sized my units so I wasn’t running them on their max settings. This is more expensive, but the result is a MUCH quieter space. I have the cost broken down on CFM/CADR depending on setting vs what I paid for the unit to get a flow per $1. I find the MA-125, MA-40, and MA-112 to do decent. I can DM you some of that info if you want. I’ve contacted Medify about their website and literature. They are inconsistent on the information posted on their website vs what is found in their manuals sometimes. If I’m in doubt about noise levels va flow rate, I go with the higher dB rating so as not to be disappointed. The MA-112 is VERY quiet on level 2 and not a bother on level 3 (it appears the MA-112 Pro flows more at the same noise levels vs the MA-112. The cost vs CFM is also better with the MA-112 Pro vs the MA-112 on these settings) Level 4 it is quite loud, and is moving a LOT of air. I do not use level 4 on my MA-112. I have been very satisfied with my MA-112. If you want, I’d be willing to work with you on the math to size a unit appropriately for your space and you’d be able to compare the requirements vs noise levels you think would be acceptable to you. I myself won’t tolerate a loud unit. It’s annoying when hosting or when w/ a SO/partner or when watching a movie. I can say the MA-112 in my Master Bedroom pretty much runs 24 hours on level 2 and I never really think about the unit. Lol. Just watched Pacific Rim again last night and it was business as usual. Never really notice the unit.

I use a MedifyAir MA 112. I Run It on fan speed 2 and get about 6 months at a time out of the filters. I have a family of 4, 1 cat, and 1 dog and have seen a huge reduction in dust.

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.

medify needs more love. those medical grade H13 filters are legit

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.

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.

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.

We use medify air purifiers

Honeywell, Levoit, Medify, Coway

It depends on the size of your rooms, and how much noise matters to you. They will all be great for pet hair, dust, and have models at about $250 to $300, for your total $600 budget for 2 units -- but you need to get models that appropriately cover the square footage in each room. Typically models will advertise the square footage they cover on the highest setting -- which is the loudest. You want to be able to run it on lower settings most of the time, so check the square footage they cover on lower settings, and/or "overbuy" for your space. Also check the pricing for a unit's replacement filters -- that's an important cost consideration. Finally, if you can swing it, I also recommend units with activated carbon / VOC filters for smells, when you have pets :)
