Medify Air - MA-125

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 couldn’t find that exact model on the AHAM directory, but looking at its specs I’m actually interested in this now for my downstairs possibly. I may have overlooked it for my bedroom because it’s 0.1 microns vs the 5500-2 is listed at 0.003 microns, but I really like the sqft coverage and CADR.. and the price! Thanks for mentioning I might be getting this next.

Sorry this is so late! I got a medify ma 125 for the downstairs Here are some quick stats off their site “2051 sq ft Can clean in 30 minutes* 930m3/h Clean Air Delivery Rate† 99.99% Captures of particles down to 0.1 microns*” I like it, but I think I like my winix 5500-2 more! I like the light that changes color and automatic changes fan speed due to a change in air quality. If I spray a cleaning product near by it goes off instantly and tries to filtrate. If my medify is on auto it’s steady at fan speed 2. I can’t imagine my air downstairs always being the same and not needing a higher fan speed.

Personally after looking at all of the ones you mentioned and buying a levoit 600s (which isn’t great) I ended up going for Medify MA 125. Better airflow and I have independent sensors that verify better reduction in particles

I like the ma-125 as my main filter because it moves air and gets circulation infiltration going and has a fairly accurate filter built-in. Then I use a much more focused filter for small rooms or wherever I am. The big filter takes the load off the small ones of it it doesn’t have to filter out the large particles. But I’m also dealing with Covid, micro plastics, and all allergies and having to have guests with sensitivity

I will also say that I have a Levoit 600 S and I’m very disappointed in it. And I also have a mod plus which I love so much but it just does not move air like the MA125 I use a sensor hooked up to Home Assistant and just watch these different ones work and I kind of wish I hadn’t bought the levoit

I have multiple Medify Air units, the main big one is the 125 model I believe. I live in a very dusty area with 3 dogs, also get smoke July- September a lot and it’s been able to handle all of these things. It’s several hundred dollars but I was able to use HSA money for it and for the filters which last about 6 months. I also have Merv 14 filters both in the furnace and where it comes through into the house which helps a lot too.

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.

My partner and I use Medify air purifiers, I'm generally a fan but haven't tried others so my frame of reference might not be the best
