Medify MA-40 Air Purifier with True HEPA H13 Filter | 1,793 ft² Coverage in 1hr for Smoke, Wildfires, Odors, Pollen, Pets | Quiet 99.9% Removal to 0.1 Microns | White, 1-Pack

I use this purifier for my living room which basically includes my shoes and where my cats litter box is, the kitchen and my TV and computer setup wheee I have a desk for plants, for my gaming, and for my work, so three areas. I also have a TV my cat sleeps on. I’m not an expert in purifiers but I know that this product does a good job at least in purifying the side which my shoes and litter are not on, leaving me free to feel good about being there and not spending too much time in my room now. It’s been such a huge benefit. Now, as the shoes and cat litter are on the side on the kitchen, I actually place on of the purifiers side facing the litter and shoes and feel more comfortable doing more cooking in the kitchen. I notice less smell after cooking, basically pure air the next day. Disclaimer, I do use an air fryer so it greatly limits smell. I bought a Honeywell purifier for my room which is about 100 to 130 SF. The living space is probably a total of 400 SF and I estimate this actually purifies 75-100% of the space. Therefore I must say there is a chance that you get what you pay for in this product, in terms of circulated purified air flow. The quality based on filters is indeed top tier. This purifies more air than a Dyson which hardly has any air it actually takes in and purifies. This is because this purifier in particular has two sides of filters that are bringing in more air than the purifier above which is pushing clean air out. Unfortunately there isn’t necessarily circulation but I assume the upward flow naturally makes its way around the living room. However, it’s quite obvious with the design there is a lot of nice clean air circulating. I feel much more comfortable in my living room and really look forward to blasting this baby to do my gaming in the other corner, and I am looking forward to working at my standing desk every morning as well. I can say that I don’t need to open the door to let clean air at all. I think it’s a great investment at least in terms of design, clean air flow and power, but I am not sure about how much square footage it covers. I would imagine there has to be a premium for the design and higher quality filters, and 4 different levels of power. There is also a very pleasant sound when turning it on and off, and it looks quite modern as well, complementing the space right at the front door, so it cleans the air of the litter, shoes and kitchen.

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 Amazon 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 Amazon 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.

This machine is a very nice looking piece of equipment. For its size it is not obtrusive. The glass top covering the control panel is a nice looking feature as well. It makes a soft sound on low and even in the high position it is not “ loud.” No worse than a fan imo. As for air movement it works well. It is actually a terrific fan. The filter is easy to access. My only thought would be to have two hand holds on the machine instead on just one. One hand hold causes the machine to tip when picked up and I can see it slipping from my grip and hitting the ground if I’m not careful. I don’t think it would take a fall well. Also the two releases on the filter cover are thin plastic. They could become an issue as well if your not careful. It is impossible for me to speak to it’s air cleaning properties though without some air quality testing. I live in Northern California and purchased this to help filter harmful air caused by the area fires. I have great windows and doors that seal well. I feel that adding this machine does help with the purification of the air in my home. I never smell smoke and I don’t feel I’ll effects ( soar throat itchy eyes ) like I did before using the machine. I do have Asthma and I think the machine helps and does work. It’s only my opinion based on the lack of previous I’ll effects. I would buy another and my gf ordered one as well. Unfortunately the company is claiming they are far behind in shipping and are not the most forthright in communication. But I do like the product so we’re are waiting to see what happens.

Bought it to repair smoke-infused air, only semi works, going to add an ionic system to it.

Please see additional comments on other registered model the MA 14, for which I purchased (on sale ) a 4 pack of filters and than a 2 pack (for one ma 14 unit dual filter . These are great products. Better than the $1200 model I purchased with UV and only true heppa.(not heppa 13)These do what they say and are great. can in needed run so quiet can barley be heard. I change filter on the ma 14 every month as Its in a room with an asthmatic with COPD so want the cleanest air I can get. Other is in the bedroom. Our unit is 4500 SQ feet or less MAX 500 min 400 Office doesn't even know. But for summer I am getting an MA 40 for the main room, than separate the units out more. They are great. So much less dust, and for me no more constant runny nose and medication. Including mold growth on a cup in hiding w/liquid left. This no longer an issue. Thank you Mediry Air. 10/10 All the way. Oh also place one in our bathroom as the fan doesn't work. We don't run it when bathing or showering, just for odor's as I noticed hospitals were doing this for the same reason. WORKS GREAT! Hooked it up to the fan plug, plus just turn it on when doing anything other than showering or hi moisture production. That model was a an MA 15 gift. Love it. Original filter in it still going, but have replacements for a year for all on standby. can't live without. In pour unit the windows do not open. Only the bedroom, but were downtown and the dust, exhaust, pollution and sand is horrific. There's a door to the patio in the living room if we need fresh air and building has "fresh air exchange" So these filters are instrumental in keeping our air fresh and healthy. Keep on coming out with great products. I used the older ma14 filter over the Air conditioner intake and seal it well. Bought a 2 pack just for that. Great fresh air all around because of Medefy. R.

O purificador é bem pequeno mas faz muito barulho nor níveis 2 e 3 pra dormir. O Pior é que pra devolver a Amazon só reembolsa R$50 da remessa e EM CARTÃO PRESENTE! Um absurdo isso. Uma armadilha comprar itens importados por aqui.

This is a quiet, efficient little filter that made the air noticeably fresher after running for just 1/2hr on medium in a moderate sized room. Sleep mode is virtually silent. Even on Medium, the sound is not intrusive. Purchased one for myself and one for my elderly parents. They are just as thrilled with theirs. Don’t be fooled by the excellent price, or small size. This is a lot of bang for your buck in a tiny package.

Very quick delivery - could get it the same day, so that was what sold me. And the high quality filters, especially for Covid. This is a reputable company too, so little chance of being scammed with false promises. Replacement filters are also easy to order, which isn’t always the case with air purifiers. It’s very light to carry around room to room. Super easy to use, plug it in and there are 3 buttons - power, turn the lights on/off (nice for at night) and speed. Doesn’t have a display to know the current air quality, so it’s hard to tell if it’s making a difference, but, again, it’s a reputable company, so I assume it is. It’s pretty loud on max speed. I measured the decibels right beside it with my iPhone - sleep mode is really quiet at 40 decibels, and each setting goes up about 10 decibels, so setting 3, which is max, is about 70 decibels, which Google says is comparable to a hair dryer. Unless we have active pollutants we want taken care of, we generally keep it on 2 during the day and it’s fine. Overall I’m happy with it and would recommend it, especially how light and easy it is to move from room to room. Only gave it 4 stars because full speed is loud and there is no air quality display.

It's quiet, stylish, affordable, and so far, has lived up to its claim of removing 99.9% of harmful toxins including allergens, odors, and more down to 0.1 microns in size. Also love the lifetime warranty.
