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.

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.

A cat sitting client of mine has the bigger version of this Medify MA-40 Air Purifier and they swear by it, so I decided to order this model for my one bedroom, one bathroom (720 sq/ft) apartment. I couldn’t be happier!! This is the best air purifier I’ve ever bought. It has really helped my allergies. Not to mention that it has helped my senior cat’s respiratory issues as well. He sneezes significantly less and breathes better overall. Highly recommend!!

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.
