GreenTech Environmental PureAir 50 Air Purifier

I tried several different models of these things and this is the only one that actually worked really well. After a day in a room you notice the ever so slight ozone smell and any other odors go away. Although it says it doesn't emit ozone I was concerned since it worked so well and did have a very slight ozone (clean) smell... so I purchased an air quality tester before I got more of these and was happy to see no difference in ozone in the room so I verified they were safe. I have one of these in every room now and the whole house smells good.

Please don't buy this!!! A huge waste of money!!! I had bought this product with high expectations after watching the review of the product on YouTube. The unit did not provide fresh air as promised in the description of the product. At low settings, there was no visible difference to the air. At medium to high settings, it gave off a stinking smell similar to that of rotten eggs. At all settings, it emits a high pitch sound making it unsuitable to keep it anywhere near the bedroom unless you are not sensitive to high pitched sounds while sleeping. I have requested for a refund, but there is no reply from LUMA brands - the seller of the product.

I waited a solid week before writing a review because quite honestly I didn't think a little wall plug in would work, but I was willing to try it. Holy crap. Within the first 4hrs there was a SIGNIFICANT difference in the air quality and smell in my home. There's 9 indoor cats and we have 4 auto boxes and 2 traditional boxes, but even with constant upkeep the cat smell persisted. A majority of the boxes are in one room so figured it would be the perfect testing room. It's honestly insane how much different the house smells. We also have 3 dogs and now when you enter the home you smell the dog beds in the front room and NO CAT SMELL. I'll be buying at least 2 more of these to spread throughout the house. Yes, it does whine on the highest setting, but I only left it on that setting for the first couple days and then adjusted it down to about the middle and there's barely any sound and the scent reduction is still amazing. If you have pets, just buy it and thank me later. Way better than scented plugins that just try to cover, this REMOVES smells completely. I'm still in awe. Def one of my best purchases this year.

Product is awesome. Simple and easy to use. I like the fact that you don't have to purchase any UV bulbs or filters for the product. It really freshens the air quickly and is not too noisy or loud when it's running. I will probably order additional ones to use in my apartment.

I purchased three of these to try to clear out some of the constant musty smell in my home, as well as the smell of the litter box that travels up from the basement no matter how clean we keep it. I plugged one in at the base of the stairs, one in the living room, and one in the hallway leading to the bedrooms, and while I'm still adjusting the dial for output as well as their final locations, I could tell the difference immediately. It adds a scent-quality to the air similar to hydrogen peroxide, which was very interesting, but also very satisfying in that it got rid of all the other less-than-appealing smells. 5/5 stars for functionality. I have two complaints. The first is something I will largely ignore due to how immediately and successfully the yuck-smell has dissipated from my home: These guys are LOUD. It's not the worst loud-fan sound, but there is a very noticeable hissing sound which increases in volume depending on how high you have the output set. There's no getting around it unless you turn the device off completely, which of course defeats the purpose. If you are sound-sensitive, this could be extremely disruptive and definitely something to take note of. The other and one that irks me to no end - the steady green glow that is put off from the dial is *extremely* bright. There is no way to turn it off, so I am stuck with this awful green that is bright enough to light up a room when all other lights are off - I would absolutely not be able to sleep with one of these in my bedroom. I will likely be purchasing some led dimming stickers, or covering it with electrical tape, but to me, this is a design flaw that could be remedied easily. Having said that, with how effective this is at odor control, I will likely be purchasing one or two more in the future if I need more square footage covered.
