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.

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 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 bought the Medify MA-14 Air Purifier for my bedroom, and it’s the perfect size for the space. It’s incredibly quiet at night. I actually had to triple check to make sure it was running. Setup was very easy and straightforward. One important tip: don’t forget to remove the plastic wrap from the filter before using it. It’s easy to access from the bottom of the unit. This purifier does an excellent job cleaning the air and eliminating odors. I used to wake up to a lingering smell in the room (possibly from the humidifier), but since using this unit, the air feels noticeably fresher and cleaner. It keeps the room smelling good without being overpowering. Just clean, fresh air. I also own the larger Medify unit for my living and dining room, and it works just as well. My kids have allergies to cats and dogs, and this has helped them so much. We didn’t have to consider getting rid of our pets, which means everything to us. I honestly wish I had bought one sooner. Highly recommend!

I'm very happy with this purifier. As was mentioned in other comments, I question the purifier's blue light which would indicate excellent quality air. Upon startup, after a minute of operation, the light always reverts to blue. I don't think the air quality had been horrible previously, but I'm not running the purifier because I thought that the air was of excellent quality to begin with. Odors Since we don't have smoke in our home or any visible contaminants, odor is really the only result that I can judge for myself. I do not trust the light in this machine that stays on blue constantly. I was not expecting much of a difference in odor after researching purifiers. I had read that charcoal filters don't help much because in many purifiers the air is not in contact with it long enough to make a difference. It took a couple of days, but the difference in odor is amazing. There was initially a very distinct odor in the air. I can't detect any odor any more. While I have no way of proving that other contaminants in the air have been removed, I really have no reason to question it either. Ionization This is just an extra feature of the unit that I will never use. There is question about how well this technology works and whether it causes more problems than it fixes. I cannot say how well this feature works. The best part about the ionizer is that when the purifier starts, the ionizer does not automatically start and I never have to use it. Filters They're a bit more expensive than some of the other models than I had looked at, but they are a higher level of HEPA that will filter the air better. Given the difference in quality, as long as I'm paying for filters to clean the air, I'll take the better ones. Filters are also very easy to install. Air quality indicator Apart from having to buy an ionization system that I didn't want, this is my only other problem with this machine. While running, it ALWAYS shows excellent air quality. There are only 3 levels of contamination indicated so even if I knew the light was working properly, it's only a broad indication about how bad the air might be. Judging by the only criteria available to me, odor, the purifier has made a big difference in our indoor air quality so I'm just ignoring the light. All in all, I'm very happy with this. While I don't trust the air quality indicator and I'd prefer not to have to buy the ionizer, these issues are not sufficient for me to lower the rating from 5 stars. It filters smaller particles than other purifiers on Amazon, the price is not significantly more for this capacity of purifier, and I am so much happier breathing the odor-free air that this purifier produces. I don't have reason to buy this purifier again (life-time warranty if I sign up within 30 days on their website and continue to change the filters as required by the warranty), but I am considering buying other purifiers from the same manufacturer for other, smaller, rooms of our house.

We are very happy with this machine. It seems well-built, and is somewhat large and heavy, but not unmanageable, having wheels on the bottom. This can be handy, as the noise level on level 4 might make you want to move it around some to find the best balance between air circulation and noise. It is quiet at levels 1 and 2 (at level 1, I measured 24 dBA at 5 feet and 22 dBA at 10 feet) , reasonable at level 3, but somewhat loud at level 4 (54 dBA at 5 feet and 43 dBA at 10 feet. Our refrigerator is about 34 at 5 feet) We have had a large amount of smoke in central Texas for a couple of months, due to both agricultural burning and wildfires in southern Mexico and Central America. The outside PM 2.5 has been hovering around 100, but occasionally spiking to over 150. Due to having a person with impaired pulmonary function in the house, we monitor both outside and inside air quality. We have had a much smaller air purifier in our bedroom, and we have verified that it works in that room, but it does nothing for the rest of the house, which is over 3,400 square feet with high ceilings in every room. Our inside monitor has generally been about 70% to 90% of the outside reading, with the ratio being higher when the wind is blowing hard and forcing smoky air through the house. When I first turned this on, the inside level dropped within minutes from 80% to 40% of the outside AQI. If we run this new unit on high, we can generally keep the inside AQI to a range of 20% to 40% of outside AQI. The machine is loud on level 4, so it cannot be used at that level in the bedroom, and even level 3 would probably be wearing after an hour or so. So, we use the device in the great room, which is quite large, with ridiculously high ceilings. This substantially improves the air quality in the bedroom as well, but this is definitely dependent on wind velocity. When the outside AQI is high and the wind is blowing hard outside, and we are not in the great room, we run the machine on level 4. This afternoon, with moderately high wind and outside AQI at 120, we were at 54 inside, while running the new machine at level 1. We increased it to level 4 about 20 minutes ago, and the inside reading is now 36 and heading downward.
