  • Love! Medify Purifiers Don’t Disappoint!
Color: White Size: 1-Pack Style: Air Purifier
The media could not be loaded. I absolutely love Medify air purifiers. This is my second purchase, I also have the MA-50 (which is in the main living area). I purchased the upgraded MA-40 on prime day for my home office. This is also where my litter robot resides for the cat, so having a purifier in there is important to help with odor control. I previously had a Winix 5500 in there, but it ultimately didn’t last and died a few weeks back. So the timing of the prime sale was perfect! This air purifier is modern and fits in perfectly with a contemporary environment. I would equate my aesthetic to an amalgamation of farmhouse/bohemian/mid-century modern. I like that it’s sleek and doesn’t stick out like a sore thumb. Traditional air purifiers tend to be a bit bulky, this is not. But! That’s not to say it lacks in power! This perfectly fits the expression of “small, but mighty”. You can tell these purifiers are effective. When sunlight streams in the room you don’t see dust particles in the air. I have two dogs and three cats and I swear that having quality purifiers eliminated my need for allergy medication (at least for most of the year - they don’t help with outside allergies!). In addition to being effective, one of the best features is that it’s QUIET! Even on the highest setting the purifier is more quiet than a traditional table fan. I included a video so you can hear the different settings. The video audio starts with the purifier on the highest speed setting, changes into to sleep mode, and then progresses back up to the highest setting. If I have any cons to this purifier, it would be that the genuine H14 filter replacements are a little pricey. They are presently $69 for one or $129 for two on Amazon. You get can them from the manufacturer directly as well. Pricing there is the same, but there is additional cost savings if you use their subscribe and save option - that reduces the cost of two filter replacements by 30% on your first order, bringing the total to $90.99. Future orders have a 10% discount ($116.99/2 pack). So there is a little cost savings to buying in bulk through their subscribe and save option. Shipping is free from the manufacturer, but it does take 5 to 7 days for your order to arrive. It’s funny how Amazon has created such high shipping expectations for us these days - anything that takes more than two days to arrive just seems so unreasonable! Anyway. I digress. I do want to point out though that, you must use genuine filter replacements and replace them, “at least once every four to five (4-5) months or after 3,000 hours of use (whichever comes first).” in order for the lifetime warranty to remain in effect. Lifetime warranty?! That’s pretty great and shows that this company stands behind their products. Just be sure to register your purifier on their website when it arrives (or at least within the first month) so they have your purchase on record. After 30 days, whether or not they honor it will be based on your proof of using genuine filter replacements since the original purchase date. Overall, if you’re looking for a high-quality air purifier, with options for both ionization UV light, you cannot go wrong with this Medify model. Medify purifiers as a whole are fantastic and the company stands behind their products. Five stars! ... show more

  • Effective and Powerful!
Color: White Size: 1-Pack Style: Air Purifier
Came in perfect working order with styrofoam for protection. Very easy controls and operation. I set it up in less than 10min with some light reading. The first test was a 10 x 10 room and after a hour, the difference was very noticeable. The room smelt less odiferous (lol) and with the lights off, and my phones light, I couldn't see any particles! Not the quietest unit but that's because it's very effective! You don't need it running all day. Definitely will also be using after housework in each room and for upcoming allergy season. Highly recommended! All thumbs up! ... show more

  • Seems a bit noisy, otherwise I think doing a good job
Color: White Size: 1-Pack Style: Air Purifier
Has all the features I wanted. The replacement filters are top notch. If you use it 24/7 you need to replace the filter every 4 months to keep the warranty active. The noise level is not bad, just louder than I like. Also, I can’t tell the difference between “sleep” and “low”.

  • Great product , it’s a little louder than my 112 machine - waiting for added benefits !!
Color: White Size: 1-Pack Style: Air Purifier
Bought the 112 and working so well but we needed more so I purchased the MA 40 , it’s a little louder than my 112 but doesn’t bother me , we put this in area where cat is only allowed in , a little early to tell of this added machine and it’s health benefits for me , I can truly say these machines work !!! Well I have been using these machines for a constant month + - I do see a difference and I’m getting back to myself - I also combine the allergy spray called ‘ Allergy Asthma Clean - the spray works very well - never knew cat allergies could cause chronic fatigue BUT they absolutely can- I’m living proof - my wife’s cat is 16 , I will not get rid of the cat but at least I have answers as to why I felt like I did - Every time I left our house I’d feel great when I’m away 1+ more days but when I came back again within 2 days the chronic fatigue happened- this is all integrated with your fight or flight , your adrenals take abuse if it’s always fighting off allergen and in my case a cat - Again these are working for us and made a huge difference - I’m just a regular guy suffering and this product and the allergen spray has made a HUGE difference - I’m not paid or any BS like that ! Just an honest opinion - be safe Doug ... show more

  • Costly TRASH
Color: Black Size: MA-40-UV-1-Pack Style: Air Purifier
I followed all their directions. Plugged it in, chime rang, lights flashed once. Then DEAD. And the unit will not turn on at all, in any outlet in my home. Other negs: For what they want for this, the design is lame: air intake/outflow is too close to the floor, unless I could lay it on its side on a table or cabinet. That might void the warranty on this flighty, non-working, costly hunk of junk. The handle is dumb, being on only 1 side, with nothing to hook you fingers into. I felt like I was going to drop it each time I moved it. The lifetime warranty is only good as long as you use their filters, their way. That's ok except that the 3 filters are all in 1 chunk, that will set you back about $60-65 every 3 months or so. I've had a lot of HEPA air cleaners, but NEVER one that needed the most expensive of the filters, the HEPA, replaced more often that about once a year. This one wants you to change it 4 times a year! You might as well buy a new unit every year, when it goes on sale. I was always able to vacuum and or wash the pre-filter to extend its life too. Can't do it with his one. There is no manual with it; you have to get it online or write to them to have them send you one. I think that reflects a lot of hubris. There is no remote or app. But do they believe they are somehow oh-so high tech? Well, I didn't really need high tech. I need something that WORKS at least as well as is stated by them. I spent a lot of time researching and comparing air cleaners (they really don't purify anything–only clean). This was supposed to be so much better than it is! Now I have to waste more time packing it up and getting it to a "location". ... show more
