Medify MA-112 Air Purifier V3.0 with True HEPA H13 Filter|5,948 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 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!

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!

Pros: Small portable size - Small enough to sit on small stand in bathroom or toilet tank Relatively cheap Easy to find replacement filters that aren't ludicrously expensive On low fan setting very quiet Led lighting good for night Does a reasonably good job of filtering dust particles Overall a good value for the money Cons: Maybe it's just me but the carbon filtration for odors doesn't seem to be all that effective Having to turn unit upside down to replace filter causes dust to fly all over the unit and area you are in Not made in USA

We discovered this exact model while visiting a walk-in clinic while traveling. My wife's allergies were out of control at the time and we chatted with the doc who gave the unit two thumbs up. So far, it's been excellent. After a few hours I noticed the air smelled different...not that there was a new smell, but a lack of smells I didn't realize were there. The first morning after use, my wife said her sinuses didn't bother her as much as normal in the mornings and proceeded to demonstrate a deep nasal inhale (we live next to a state forest, so lots of pollen, mold, etc.). The unit itself is straightforward. You plug it in, you replace the filter in the back when needed, and that's about it (the filter is sealed in a bag inside the unit, so make sure to remove it from the bag prior to use). We like the "Sleep Mode" setting, which is essentially the same as low fan mode, but all of the lights on the controls turn off, which is great for those of us who find light sources distracting when falling asleep. We turned the Ionizer function on for a bit, but decided to let it run without it for a while. It's not necessarily a cheap item, but it's a relatively inexpensive way to improve the air quality in a home, which can improve the quality of life for everyone inside, so that makes it a bargain.

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.

Absolutely love this product! It’s easy to use, cost effective, and keeps the air in our baby’s room fresh! I’ve seen a huge reduction in dust since getting this! I love that the lights are not bright, it’s quiet, and it blends into the background because of its simple look.

This was a replacement for one that ran continuously for over 8 years. I replace the filters every 3 months. It keeps the air smelling fresh and clean in a home with dogs.
