Review: This unit excellent, but QC issues on second order. - I ordered two of these last spring. The first one was perfect and is serving me well in the room with 4 litter boxes. Whenever I scoop the boxes the machine, really does detect the activity and the extra dust in the air and amps up to a faster speed to clear the dust. Even though it’s in this one room, it has really helped the ground floor of my 2 story home become less dusty. And in most modes it is quiet enough that my cats actually like it and like to lie down in front of it. Strange, but I’m glad they like it. The feature sets are listed so I won’t go into those but everything works well. I don’t use any night mode, though, so I can’t speak to that. I just run it on auto and once in awhile use the ionizing cleaning. Much to my relief, there have been no weird burning plastic odors as reported with some other brands in the 8 or 9 months I’ve been running it. I did get a separate warranty registration in the mail because apparently one was omitted in the shipment sent to me. I found that interesting. I do wish I had registered within the prescribed period of time, but I’d put it aside while I dealt with other things and just let it go. The downside is that the replacement filter looks really expensive at $69. It’s an excellent quality though, and likely lasts longer than cheaper ones. Okay now here is where it gets weird for me. I decided I liked this filter so much that I would order one for our master bedroom, which is pretty large. And the unit arrived. But to my distress, it was put together weird. Seams were crooked and there was a lot of rattling noises inside. It didn’t look like it had been damaged in transit. It just apparently went through a very bad day on the assembly line. I turned it on and it ran. But the rattling noise was disconcerting. Basically it was horribly defective and not usable. And I was going to contact the sellers but then I noticed something odd in that apparently my order was still on its way. I was so confused. My name and address was on the box I had just received but the tracking number was different. And then my mother-in-law fell ill and we had to drop everything to take care of her. Meanwhile, as I’m on the way to take care of her, ANOTHER unit arrived to my house. I checked my desertcart account and only one second order is on record. And this third unit was the one. I have no idea why I was randomly sent a completely busted up unit. But I dragged this third one in and it sat in my foyer for a couple of weeks while I dealt with my family crisis. I would have assumed perhaps the sellers realized they made a mistake sending out a damaged unit and sent a good one, except there is no record with desertcart for that busted up one. Finally, I got a free moment from hospital vigils, so I pulled this third one out and externally it looked okay but internally it had something loose and rattled badly, too. So I set it aside intending to try and get all of this straightened out with the seller. But my mother-in-law got pneumonia and passed away. In dealing with the hospital vigils and her funeral, we didn’t have the time or the energy to deal with this. So all these months I’ve had two broken units in my bedroom. I just said the heck with it and ordered a Dyson for the bedroom during a massive sale. Meanwhile my original is serving us very well in the cat litter box room. I’m way past the time to register for warranties or get warranty service on the defunct units. I will just keep the broken extras for parts for the good one. So, basically it’s 5 stars for the absolutely fantastic working unit. But with a caution to do a quality control check when your air cleaner arrived and register your machines for warranties.
Review: Must buy - Went to my doctors office and saw this air purifier as the receptionist it’s nice and quiet gave me the name and bought it. It has performed. Outstandingly does exactly what it was supposed to do clean the smells out of my kitchen and made the air a lot better in my house must buy.

## Questions & Answers

**Q: Unit is now unavailable from amazon. i'm concerned that the company is flybynight and i won't be able to get replacement filters. should i return?**
A: I strongly advise NOT purchasing this unit for shipping by Medify. That's because Medify will make you wait and wait indefinitely for an item that they don't really have in stock. Whenever it comes in stock for shipping via Amazon Prime, that would be the time to buy it.

As for the filters, third parties should be able to manufacture them, so no worries.

**Q: why has the sensor been staying in the 600 range? No cooking,fumes,anything near it.**
A: IMO, the sensor is likely faulty. I have three MA-112's and they rare display above .009 unless detecting cooking smoke. Contact the seller; they have benn very helpful for me in the past.

**Q: Is it certified by the asthma and allergy foundation?**
A: Not currently, but I would be happy to send to them. Could you provide contact info 

Thank you

**Q: I bought the medify air ma-112. i set it up and everything seems to work except, the digital display cycles between l00 - 800 - 900 - 600, and repeat.**
A: Did you turn it off or set it to a speed for a bit and see what happens 

I have never had this problem from a customer. Perhaps the sensor was damaged in shipping?

If it does not go away contact us at Medifyair or send back to Amazon Prime for a replacement unit and they will give you a label to ship that back

No worries we Stand behind our products 100%

### ⭐⭐⭐⭐⭐ A defined difference in the air quality
*by A***R on April 3, 2020*

I bought this Medify MA-40 2.0 Medical Grade Filtration H13, True HEPA Air purifier during the 2020 Corona Virus pandemic. We have 2 large dogs, a kid who is back from college early due to the pandemic and my wife is a nurse at a local hospital. But it was not only those items that pushed me in this direction. I always change the furnace filter regularly. The first floor of the house has carpeting in only one room. The second floor is mostly carpeted except for the master bedroom which has an area rug that extends out a little beyond the bed. It was when I was in the hallway one morning and our sons bedroom door was open, and so were the curtains. The sun was shining in. As I looked towards that window, in the suns rays, I was astonished to see all the airborne particles/dust/or whatever. It just did not spell healthy air inside my home as far as I was concerned. I can tell you that at that point, for me, that Corona Virus Pandemic or not, I didn't like what I was seeing at all and I was going to do something about it. I kept thinking how it seems like every winter, that winter cough seems to stick around, once it starts, for the rest of the heating season. So I started looking on line. I saw several different manufacturers and models on line. There were lower cost models and there were higher cost models as well. for myself, I determined this was the one that I wanted to try. So I cannot tell you whether this model is just right, overkill or insufficient but I can tell you this. I first started it up and ran it on the first floor after I opened the package when I came home from work. Within a couple hours, I felt that I could tell a difference. I asked my wife what she thought. She was a little on the fence about it but felt a little something different. That night, when we went to bed, I took it upstairs and ran it in the hallway (leaving all of the bedroom doors open. The next morning, I left it in the upstairs hall when I left for work. When I got home, and headed up the stairs, there was a defined point at which the air quality was so noticeably different. Again I asked my wife if she noticed the difference. This time, there was no hesitation. She agreed that it was definitely better air quality upstairs. So you may be thinking is this guy going to order a second one so that he has one on both floors. I would like to, but I am going to save for it. I might even try one of the lower cost ($99) models I had seen just to see if spending that extra money is worth it. Sound - So I do not operate it at the highest fan level, in part, due to the sound. The level that I have it is the lowest level you can have and have the ionizer on the system working at the same time. So the whisper mode, I cannot comment on because I don't use it. I could see it still being a little loud for some people though. My wife commented that she had woken up during that first night and she thought the sound was the water running. Recommendation: At this point, I can say that this thing really has made a difference, I feel difference breathing, already coughing less, and I am not compromised in any way so I have no reason not to recommend it. If I end up buying a lower cost unit and it works as well, I will try to update. Maintenance - Filter replacement cost does look pretty high (I think I saw $69 for the filter). It will be interesting to see how often I find that it needs to be replaced. Unless the lower cost model does an equally good job I will bite the bullet and replace the filters I hope this helps if you are considering buying one! Good luck on your decision
