Medify MA-40-UV Air Purifier with True HEPA H14 Filter + UV Light | 840 sq ft Coverage | for Allergens, Wildfire Smoke, Dust, Odors, Pollen, Pets | Quiet 99.99% Removal to 0.1 Microns | White, 1-Pack

For the record, I am reviewing: Medify MA-40-UV Air Purifier with True HEPA H14 Filter + UV Light | 840 sq ft Coverage | for Allergens, Wildfire Smoke, Dust, Odors, Pollen, Pets | Quiet 99We purchased this unit about 8 months ago after a water leak and having to replace the roof, insulation and and some drywall. We did not want to have to spend money on a hotel while the work was being done and we had a lot of mold because the leak went undetected for a while. The unit is not as big as I thought it would be, and honestly, I am not sure that 840 sqft is an accurate number for coverage. We used to have a Honeywell round unit that had a much higher cuft/mn output and it was amazing. Of course that one was a lot louder and it blasted the room with air so, trade off is quiet for less air circulation. But that is acceptable.Here is what I like: It is quiet, even on the highest setting, however, I do like white noise when I sleep so I was hoping it would be louder. I still use my sound generator when I sleep with this filter going. The Ionizer is a nice function, and it does not change the smell of the air, like when you are using the UVC light that produces some ozone. The unit does have UVC but it is on a timer and shuts off after a preset amount of time, not sure how long that is because I only use it at night when I go to bed. The light does not escape the unit, well not a lot of light escapes the unit but you can tell when the light is on.We have four cats, and the unit filters the air really well. My bedroom has sunlight that beams thru the window in the morning and if there is any dust in the air you can see it. If I am using the filter there is no dust, the air is 100% clean. I don't use it all the time, but right now we have a lot of fires in our area and their is a health warning out so we have it turned on and filtering the house air. The difference from inside the house to outside is stark like night and day difference. So, I love the unit, it has a nice design, clean, and works great. If you are looking for one that is quiet and works, and has UVC and TRUE HEPA this is a good one to get.I will say this, I learned a long time ago that you do not change the filters on these like they recommend as the filters actually get better over time, not worse. So unless you have a noticeable decrease in air flow, keep using the filter that you got.

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!

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!

I purchased this because my house *had* a funk odor from my aged mother. Believe me we have tried everything. The diaper genie was genius but still no matter what there is just that odor.Easy to use. I plugged it in and went upstairs to work. Three hours later, I went back downstairs because my sister had arrived. The first thing she said was, it does not stink in here. It did not!!! It was also cooler as this unit helped circulate the air better in that part of the house. I was very happy.Later, my other siblings came over and again could not get over the "funk" being gone.It makes no more noise than my ceiling fan on high. Honestly, I don't mind white noise.I also ordered a smaller unit just for her room. It is the M 25 series. Again, what a difference.I wish I had found this sooner. We have been reluctant to have guests because not matter how many times we clean daily, and keep everything up, there was just this funk smell.worth every penny! and its not masking with sprays, candles or other air fresheners!

This is a fantastic filter and I highly recommend it! It also has a UV function and my favorite is the Ionizer! By using the ionizer I reduce the dust in the air. The ions attach to the dust and it falls to the ground or a surface. After a good cleaning of this dust, it is much cleaner in my home. The ionizer really works! I LOVE this filter and Medify as a company. I have 2 of these, one for each level.Quick story: When I first got the filter I did not believe it would work very well, I was disappointed by other filters. I had tile work done in a bathroom off a bedroom. Everything was very well covered but the dust of tile and drywall sanding was a white cloud in the room. You could not see from one side of the room to the other. The window could not be opened. I put this filter in the corner of the room and fired it up. I expected it mild improvement and that it would be there all day. Within about 5 minutes, there was NO DUST IN THE AIR! The cloud was 100% GONE! The tile guys were shocked too, they never saw anything like it! I would never recommend you do this because I ruined an expensive filter and spent a day cleaning out every crevice of the machine - but this was absolute proof of how this filter really really works! Since then I purchased one for a family member and another for a different level of my home. I will purchase a few more too. I highly recommend this filter, it really works! If you hate to clean, use the ionizer too. After you get the initial dust cleaned up you will find you don't need to clean as often!
