Easy setup stylish and working as expected
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.

This purifier is a life changer! Its worth every penny and more!! No more smells & helps allergies
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!

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.
