GreenTech Environmental PureAir 50 Air Purifier

I didn't have a lot of hope for this item but I am ordering more to give as gifts. We have two cats, three litter boxes and no matter how often we clean them, there are still rooms that just have that general "eau du cat" from time to time. I've never tried an ionizer before but I'm completely sold on how well it elimates any hint of bad odor.I am aware of a slight ozone smell in the room where the device is located but I do not find it offensive. I can see where some might be sensitive to it or dislike that smell. I started out with the unit on about half power and have since dialed it back to as low as it will go. This still produces the amount of purification I need and has reduced the ozone smell significantly. I might even try turning it off every other day and see how that goes.Some users have mentioned the annoying sound. I do not find the sound or the green light bothersome but this is in one downstairs room that does not get a lot of human use so your mileage may vary. It does give off a bit of a whirring/hissing sound that increases as the power is dialed up. There is no way to turn off the green power light that glows when the unit is turned on.If you are at your wits end trying to get rid of funky odors and you aren't into covering up with heavy perfumes or detergents, I think this product is definitely worth a try.

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.

Very easy to use and doesn't take up any space. You just plug it in an outlet. This little purifier works great. Also great for traveling. I have purchased two of these. One for my work studio. The studio has no air circulating so the air can get stale at times. I can actually smell the clean air. And the other is near my cat's litter box. Also cleans the air when they use their box. I'm very happy with my purchase.

I like that it has adjustable fan. I used this while watching some cats. One got inti a hide hole and urinated. I tried my best to get it cleaned, but I just couldn't reach it even though I lobbed some enzyme cleaner at it. This worked almost immediately. Also works on kitchen cooked onion smells. Also had a steam cleaned couch that still smelled like dog. Plugged this in and 3 days later the smell is gone.

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.
