Medify Air - MA-112

**Look at the Medify MA-112** 1. Austin Air HealthMate over the newer IQAir ***GC series***, because the Austin has lengthier and affordable filter replacement timeframes and cost. And the Austin also adds zeolite to aid in gas/odor filtration. See this comparison video between the two: [https://youtu.be/oKlkgxHbA\_o?f](https://youtu.be/oKlkgxHbA_o?f) Contrarian comparison (and decent channel): [https://youtu.be/YbsvedBljlY?feature=shared](https://youtu.be/YbsvedBljlY?feature=shared) There's the newer Austin Air HealthMate Plus, but I don't know how much activated carbon this newer version contains. Customer service for IQAir in the U.S. seems non-existent. Note that the air flow, referred to as clean air delivery rate (CADR) isn't great for either the Austins or IQAirs--they range from 250 to 300. Great filtration, but air flow is key. 2. Also look at the new IQAir - Atem X, which is AHAM-certified at 415 --much higher than the other IQAirs and the HealthMate. [https://www.ahamdir.com/room-air-cleaners/](https://www.ahamdir.com/room-air-cleaners/) 3. I highly recommend looking at the Medify MA-112, which has one of the highest (if not the highest) CADRs (\~600) on the market--twice that of the Austins and the IQAirs--and is known to be quiet for its size. It's also on the AHAM certification list.

What’s the sq ft of the room? What speed do you run the living room ma112? And are you aiming for a minimum or desired ACH?

for 5ach (the min recommended for allergies) you would need ~approx 1100 CADR/cfm for the whole house (but more CADR is better) . If you run your ma112 at speed 2 that’s only 289 cfm. That’s not doing much. I’m guessing you use that speed due to noise? Smart Air blast is 1200+ CFM at only 43db (ma112 is 56 db), would be a good choice imo. Individual purifiers in the bedrooms along with the other living spaces would be best though. Suggestion: Narrow down your choices to purifiers that provide CADR that’s 2/3 the room sq ft at the lowest noise level (at your budget with low operating costs 😀).

My MA-112 has the prefilter on the filter cabinet on each side. Pretty easy to clean it without affecting the filter itself. Did that design change?

Yep, I just take that #2 pre-filter and clean it every now and then.

Agree here. I have the Coway ProX and the Medify MA-112. They both move lots of air. The ProX is more quiet and built better, but is also a bit larger.

Hi! just tagged you in another post that did get some replies. We purchased a large stand alone air purifier for our main living area (medify air 112) so running that for now- but I do really want to install a system on our actual hvac unit- I still just don’t understand which is the best way to go but on the other post it seemed to say that the air scrubbers are gimmicky…. If you find anything else out would love if you could share.

Thanks. We have Coway air purifiers for our bedrooms and keep the doors closed. Just bought a Medify Air 112 for the first floor that says it can clean 2000 square ft. every 30 mins- problem is we have an open floor plan so no way to close doors

If you're actually looking for any functionality, Dyson is off the table. When it comes to Dyson's air purifiers, design dictates function, so the engineers had to consider the aesthetics of the device over the functionality. The Philips 8000 is essentially the same thing as the Dyson, Philips doesn't have magic engineers, they're using the same "bladeless fan" design. The "bladeless" look they're going for essentially uses a cylindrical centrifugal fan to force air through small channels and out from the thin gaps around the upper frame, this is completely an aesthetic design and does absolutely nothing functionally except increase noise levels and suffocate air volume output. Hence why at anything above 5/10 fan speed, this fan sounds like a jet engine. If you want a functional air purifier, look at the Winix 5510 ($165) for an affordable option, Shark HP302 ($330) for a midrange option, Medify MA-112 ($700) for a high end option. If you want functional VOC filtration, the consumer grade stuff won't cut it. You have very few options like the IQ Air Health Pro Plus XE ($1,200) or AustinAir Healthmate Plus ($855) and the other options are industrial grade filtration systems like the ones I have for my workshop. However, this is unnecessary unless you live in a city with absolutely terrible air quality. I only have gas filtration because I have machines that emit toxic fumes and UFPs.

The Shark HP302 is the largest Neverchange model. By the way, the neverchange claim is a marketing gimmick, they just have high quality pre-filters that are easily cleanable which extends the life of the HEPA filter, which to their credit is probably a HEPA13 filter and will likely outlast most other models but should be replaced after 2-3 years.  The Medify has substantially higher airflow than any of the other consumer grade options, it will be able to filter much greater volume in less time. It is pricey but you were willing to pay for Dyson and it’s around the same ballpark. You can probably order direct from their website.  The Coway air purifiers are a good midrange option. Blue air is more of a low end option.  The Winix 5510 is just the newer version of the 5300. The biggest difference is that the 5300 uses a fibrous carbon filter while the 5510 uses a higher quality pellet charcoal filter. As I’ve already said previously, none of these consumer-grade activated charcoal/carbon filters are actually effective for more than a week or so. Won’t make much of a difference functionally between the 5510 and 5300, you’re only really looking at the HEPA filtration. If you want real gas filtration, you gotta pay up for the IQ Air or AustinAir. 

I don't think the absolute best purifiers for a large room are on this list. In order to calculate minimum Clean Air Delivery Rates (CADRs), we would need your room's length x width x height. [CADRs should be at least 2/3 of your room's area (assuming an 8 ft. high ceiling)](https://ahamverifide.org/ahams-air-filtration-standards/). For wildfire smoke treatment, Smoke CADR should *equal* your room's area which again assumes an 8 ft. ceiling. The best for large rooms in my opinion would be the [Coway Airmega ProX](https://cowaymega.com/products/airmega-prox) and the [Smart Air Blast MKII](https://www.smarterhepa.com/products/smart-air-blast) as both are quiet and powerful. From the list OP has shared, the best is clearly the [Medify Air MA-112](https://medifyair.com/products/ma-112?variant=31240021180483). However, it is very loud at 70 dBA. Keep in mind that CADRs are usually listed for the top speed setting only. The top seed is the loudest. Lower speeds have lower CADRs.

The Medify Air MA-112 has fantastic cleaning performance. Unfortunately it is loud on the top setting. I'm aware of this because I asked Medify Air's customer support about a typo/error in the product manual. I was told: * Minimal Noise Level: 45.6 dBA * Maximum Noise Level: 66.8 dB / 70 dBA This is a common problem for air purifiers and not limited to Medify Air.

I would definitely switch to H13. Medify Air's H14 filters are more restrictive, so it's going to lower Pollen CADR. Pollen is quite large compared to other particulates (like PM0.1 and PM2.5) anyways. The CADRs you see for the [Medify Air MA-112](https://medifyair.com/collections/air-purifiers/products/ma-112?variant=31240021180483) are for the True HEPA H13 filters. On the same product page, they also list "CADR By Speed". But each speed is an averaged CADR for the different particulate types. Another issue: I believe the maximum value for Pollen CADR under the AHAM AC-1-2020 standard for any purifier is 450 CFM. If you check the [AHAM Verifide Directory](https://www.ahamdir.com/room-air-cleaners/), the Pollen CADR value for the **Medify Air MA-112** is actually >450 CFM.

Weird. A year or so ago, the MA-112 PRO was listed along the other consumer-grade units. It then disappeared, reappeared under Medify Air's commercial-oriented units only, and is now for sale alongside consumer-grade units again. Anyways, the [MA-112 PRO](https://medifyair.com/collections/air-purifiers/products/ma-112-pro-air-purifier-white?variant=42313765486659) is really powerful in terms of cleaning. So is the [MA-125](https://medifyair.com/collections/air-purifiers/products/ma-125-air-purifier?variant=39635063111747). There are two main drawbacks. Both models have integrated pre-filters overlaid on the HEPA filter media. This makes them harder to clean without potentially damaging the HEPA media underneath. Secondly, Medify Air has a reputation for be quite to very loud on the highest setting. The MA-112 PRO's sound level specs must be a misprint. There's no way "Sleep Mode" is the loudest setting at 56.5 dBA. The highest setting is probably in the high 60s dBA. If you're okay with a loud purifier, I might check out the [MA-112](https://medifyair.com/products/ma-112?variant=31240021180483) instead. It has separate permanent pre-filters for easier cleaning. However, it looks like the sound levels are incorrect here too. When I contacted Medify Air's support last year, I was told the highest setting for the [MA-112](https://medifyair.com/products/ma-112?variant=31240021180483) was actually 69-70 dBA.

I’d yank the Levoit units off this list unless cost is your biggest driver. While the Everest air is a good unit, the core is just not. It will clean air at first but it is cheap and the filter cost will add up over time. The lack of real pre-filters really kills these things. From your list, Medify is excellent. As is Coway 400. IQ Air will filter better than any of these units… but moves a lot less air doing so. I own one and I love it but I fully admit it lacks airflow and is VERY expensive. Alen is also good, you can optionally equip them with extra carbon which is nice. You won’t regret any of these purchases tbh.

CleanAirKits is the quietest. Dyson second quietest. My Medify MA-112 is pretty quiet too.

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.

Check out medify air , they come in all sizes and they are true H13 HEPA filters. Great customer service, I have quite a few of them in my house and love 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.

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 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

We use medify air purifiers

I have a whirlpool air purifier that is at least 12 years old that’s still going. I also like medify air.

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?

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

I have a couple of Medify units, which have been excellent. My understanding is that the Coway ones are good too. 

Had the same Honeywell for years, replacement filter is not expensive. Bought it used too for ~$70. Yes it gets loud, but I turn it on downstairs at bedtime so it runs all night then turn it off in the morning. For bedrooms I have Medify Air but the filter needs replaced a lot more often.

I really like my Medify Air purifiers! 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.

I have a medify one. It’s worlds different for pet dander.

I run a Medify purifier in my living room and it handles wildfire smoke pretty well for me. I like the filter setup, and it doesn’t get too loud.

we have had honeywell, air doctor, and medify air, as well as a random amazon one (veva). honeywell has actually been my favorite, and it’s also cheaper than the other 2 besides the veva. i am extremely sensitive to noise, and it is very quiet. 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. the air doctor is quiet too, but honestly i just don’t see a big difference in effectiveness for how much more expensive it is.  i looked for something without ozone or anti-microbial treatments, which all of the coway ones have one or the other of (the cheaper ones have ionizers which create ozone, the more expensive ones have anti-microbial filters only). all you really need is HEPA and a carbon filter. and go oversized- get one that is for an area larger than what you have. they calculate effectiveness based on it being on the highest setting, which may be louder than you want. 

I like Medify air and Dyson

I second Medify. They’re all great products.

I also like the Medify, I have one in my bedroom

Medify changed my life

Assuming that these aren't erroneous readings: - open a window or patio door a crack and turn on a fan on the opposite side of the apartment to suck in some fresh air. - get HEPA filters with activated charcoal - that will help with the VOC; we use some by Medify Air.

+1 for medify if you don’t go the box fan route. 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. 

Just get something that uses HEPA filters. We have one in every room but the bathroom (humidity from the shower is not great for the filters). I've never had to clean baseboards since using them. Winix from Costco. I also have a Coway and Levoit (lots of people like those) as well as a few from Medify. They all do the same thing. I personally prefer to get one larger than needed for the size the room it's rated for so I can run it on low - which is quieter - and still get a good number of air exchanges per hour (the room size they typically advertise assumes you're running it on high which most people are not since the higher settings are loud). Bonus with HEPAs is that they help reduce illness transmission as they clean viruses from the air.
