Medify MA-40 Air Purifier with HEPA Filter | 1,793 ft² Coverage in 1hr for Smoke, Wildfires, Odors, Pollen, Pets | Quiet Removal to 0.3 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.

These machines are made well. They look nice. They do an excellent job at cleaning air. I spent many a year in my adult, working life testing hardware and software, vetting solutions that work. I do not support products I do not believe in. We now have 3 Medify air purifiers. MA-40 was our first. We then purchased the MA-112 and MA-25. Here's why: 1. The Carolinas allergens are mighty! I have lived all over the US and abroad (NZ) - I have never experienced allergens as powerful as these. I had to armor up. These air purifiers do the job. Amazingly well. 2. We have construction of an assisted living center directly across the street. My windows do a good job keeping debris and red clay dirt out. The Medify purifiers supplement the windows' job and are a home run. Our dust levels have gone down significantly. I hate dusting, but I hate seeing and breathing dust even more. Now we do very, very little of both. :) 3. It smells good in here. Clean. Medify Air Purifiers in our home - 2 story, approximately 1900 sq ft: 1. Medify MA-112 Main living area- Open living space of approximately 980 square feet on first floor. a. Shoots air upward - filters on both left and right sides. Definitely moves air efficiently. Area description: We have a study (with french doors, usually closed) near front entrance of home. Open kitchen in the middle which leads directly into the dining area and living room at the rear. You can see clear to the back of my home from the front door. After running the MA-112 30 minutes, the air was noticeably cleaner (and we were running the MA-40 for several days up to 10 minutes before turning on the MA-112!!) 2. Medify MA-40 - Master bedroom (14 x 13). It was downstairs where MA-112 is now. I didn't want to run the MA-40 on full blast 24/7 as this doesn’t seem efficient to me. I leave it on low speed all the time unless I want to kick up air flow a notch (I get hot during sleep). a. Shoots air straight ahead - filters from behind. Moves air efficiently for the space, more suitable for medium/large area bedroom or living area. Perfecto for my sizeable bedroom. 3. Medify MA-25 - Daughter's bedroom (12 x 11) sitting on top of her dresser. Efficiently cleans the air in her room. We leave it on at medium speed all the time. a. Shoots air straight ahead - filters on both left and right sides. It's small, tidy and quiet. We hope the above break down helps. With so many options available on the market it took me a little while to pull the trigger on Medify air purifiers. We used to have smaller ones from Target (various brands) which cannot compare to these units. Not in the same ball park!

I have owned a few air purifiers all around $150 price range. I figured those purifiers would help our daughters allergies as well as remove smells in our home, mostly our German Shepherd. Sadly, none of the air purifiers I have owned in the past did anything. They felt as if they were just another fan in the house. So I decided it was time to invest in something a little more powerful, and that meant more expensive. I was decided between the MA-112 or the RabbitAir MinusA2. The price on this MA-112 was more expensive, and since I am a family man on a budget, I felt maybe the rabbitair would be the one I would choose. Long story short, this product had a sale and I quickly snatched it up! This was probably the best purchase I have made in all my hundreds of Amazon purchases. The MA-112 is large, so as long as you don't mind something big, this unit is for you. **Reminder to remove plastic wrappers from filters before you turn it on, I almost forgot** Anyway, the amount of air its filters per hour had me sold from the start. This thing is an absolute monster when it comes to cleaning your air. After turning it on, the sensors said our house was in the 500 range, it kicked into full speed and brought it down to the 300 range, then under 100. Within about 30 minutes the sensor was reading at 008. So it did its job immediately and very quickly. After 24 hours we noticed our daughter slept peacefully through the night, no one woke up with stuffy noses, and the house smelt like one of those homes you visit on vacation that have had maids running in and out making it perfect. So even though we had no maids in our home, dog hair still scattered all over from the robot vac missing a few spots, dishes still left in the sink that I forgot to put in the dishwasher. The MA-112 hid all of that mess from a busy life, a very active dog, and allergies that have been plaguing our children, especially our youngest daughter. If you are reading this and you are on the fence about spending a lot of money on an air purifier, DON'T BE! This is a MUST buy item. I can't speak enough praise about this product. We have already had many guests and visitors who at previous times in the past, said our house smelt like dog. Instead, they said our house smelt so clean and fresh. We pointed to our newest addition of the home, and they loved the sleek look of this device, and its quite settings. On high it can get a little loud, but speeds 1-3 are almost non existent. Buy this product, and you will NOT be disappointed. I know its hard to trust strangers on the internet, but this working dad of four kids, who has a working wife, a very smelly dog due to the amount of hair she sheds, and an extremely busy lifestyle. This thing is a God send. I highly recommend this product!

I am not sure how to rate this product. I still have dust in the area that I purchased it for and it doesn't really clean the smell. Update: it works well eliminating smell of mold and other household fumes, but not on smoke. I had a smoker living in the house that only smoked outside of the house, but the smell of it was coming in when the door will be opened and closed afterwards. So, I decided to get this air purifier to clean up the air, as I liked the area that it covered. The smell never got cleaned up and it never smelled like smoke, instead it was turning into some type of stale stink. So, the smoker left and I ended up airing out the house for two weeks. Then I decided to test it again and took it to my friends apartment. Non smoking apartment, but the neighbors downstairs smoke in their apartment and the smell sips through every crack into his place. It is impossible to sleep there in the main bedroom as bedroom downstairs used as smoking room. It is tiny room with bathroom and i had this machine running on highest there for a week non stop and it was still impossible to sleep in it, as it didnt clean the air, just circulated it through the room. And the indicator never showed bad air in that room, even though it does work. Now I have it in my house, in the basement where sometimes it has moldy smell and it does great job at cleaning the air. Even though I run it on lowest, or automatic setting. Can't say that i love this purifier, but I am happy that it is doing its job for me in the basement. It's been nearly 4 month since I had it and the filter is still looks brand new. Filter lasted 5 month. Sensor turned red. I turned off the machine and replaced the filter. It ran great for a couple of days. But now, no matter how many times I clen the sensor, it keeps fluctuating from blue to green every couple of minutes. Really annoying. Seems like I need a new sensor. I contacted the company same day with an explanation of my problem, and without any questions got a reply with an instructional video. About 4 days later I received new sensor. Took me less than 5 minutes to change it and now it works like a charm. I did raise a star because of great customer service.

If you are tired of waking up with a stuffy nose or constantly dusting your furniture, this unit is an absolute lifesaver. Right out of the box, it feels incredibly solid, and the sleek glass top gives it a premium look that fits right into any living room or large bedroom.What really sets it apart is the medical-grade filtration system. Within just an hour of turning it on, the heavy, stale feeling in the air completely vanishes. It tackles stubborn pet odors, kitchen smoke, and floating dust bunnies like a champ. The touch controls are highly responsive, and the built-in child lock prevents curious toddlers from messing with your settings.When it is time for bed, the sleep mode is a dream. It shuts off all the bright panel lights and drops to a whisper-quiet hum that actually doubles as a soothing white noise maker. While the higher speeds can get a bit loud, that is just proof of how much air this machine is moving.It is an investment, and you do have to budget for swapping out the filters twice a year. However, for the sheer relief of breathing genuinely clean, crisp air every day, it is worth every single penny.

Outstanding performance. This unit removes all of the air particles that interfere with normal pulmonary functions. After three days of sleeping with Medify Air on, I have noticed major physical differences. I have more energy, a few skin abnormalities are beginning to disappear, and I feel better. It is also quiet, easy to operate, and does what it is designed to do. Choosing this item for my bedroom was a great idea.

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.

Works great. On low speed, it is super quiet, on high speed, it is decently loud white noise. Filters are easy to clean and replace. I've now purchased multiple for different rooms in my house. Controls are easy to set manually, and there is an "auto" control also. Does a great job at managing dust and (German Shepherd) dog hair in our bedrooms.

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.

Ha salido excelente. La mejor inversión de mi mes!

It is very good, straight out of the box

First, I'd like to say that the instruction manual does say to remove the packaging on the filter. Maybe they updated the manual but I didn't have issues with these instructions being clear. I purchased this air purifier because I have two cats who use a litter box in a room right off my kitchen. You can imagine the effect is not always pleasant. Now that's it's a hot, humid time of year my main floor runs the risk of smelling funky. With the air filter running in the room with the cat litter, I no longer smell anything unless the cats had JUST used the litter. This means it's successfully odor free 95% of the time. Works for me. 🙂
