This Air Purifier is one of my favorite and best purchases from Amazon. As someone who smokes a ton of weed and vape often when I’m gaming, odor elimination as well as the elimination of the dust that naturally comes along with smoking indoors was the reason for my initial purchase. I eventually became a witness to its glory during allergy season and also, during the times of the wildfires here in Cali. This has been a great purchase. So much so, that my aunt bought me a second one for Christmas so I didn’t have to keep moving my original one to and from the game room and could always have on stationary there and the other in my bedroom. YOUR LUNGS, YOUR ENVIRONMENT, AND YOUR GUEST WILL ALL BE APPRECIATIVE OF THIS PURCHASE!! I would recommend that you rinse the essential oil tray and sponge at least once a week, though. Otherwise the sponge get hard and stale and the tray becomes caked with the oils and becomes somewhat ineffective. CHEERS TO YIUR BETTER BREATHING AND SLEEPING 🔥🔥🌬️

Quiet operation and easy to use. I purchased a 2nd one for my bedroom. There is a nighttime running mode, that runs on very low speed. Filter last a long time and I'm pleased with the ultra violet light for bacteria cleaning.

I thought I was receiving a dehumidifier/air filter combo, but it was just an air filter. This was due to a lag-time on my device. Otherwise, the product is exactly as described and functions decently. It does seem to struggle filtering on high speed for durations longer than 8 hours - the air quality stays in the 20s for a few hours then shifts into the 60s around the 6-8 hour mark.

I have had a Pomoron 4-1 air cleaner for several months now. I have serious breathing allergies. I love these little air cleaners. They are affordable and they do the job. We have them in the living room and in the bedroom.

I’m not supposed to have pets where I live. But I have a cat. They do inspections every year. The lady walked right past the litter box and didn’t smell a thing! This little ionizer/air purifier really works!

Finally! A negative ion generator that actually works! I had previously purchased the 4 pack of plug in ones that did nothing. I have previously had negative ion generators so I know how the air is supposed to smell and those did nothing. The only thing I don’t like is having to replace the filter so I don’t run it continuously as I would like to.

It's been about a year since I bought this. My biggest problem, is it is a 'touch' button, which I'm not sure if that goes off of how warm your finger is to turn it on or what, but IF/when I can get it turned back on it seems to do a good job. My husband (who is a human furnace) also couldn't get the buttons to work either. Maybe I just have a bad switch system on mine in regards to the touch buttons, which is the biggest reason I didn't give it a 5 star. I have a smaller living room, which is where I keep this unit. After so much time has passed, it turns off automatically.I'm not sure if the oil tray really works, I've put a varying amount and I usually don't smell it around the room. But I do like the fact that it has both the Ion filter and the UV filter. The fan speeds are not obnoxiously loud, which is nice, although for me, I have it right behind my chair, so I usually have to turn up the tv if I have it on settings 2 or 3. I have mild allergies to about everything, with my biggest allergen being cats, which I have 3 of (and 1 is a long-haired one too..). When it's on I feel like I can breathe better in general. But, it is a lightweight unit, so if I need to move it to the floor, or wherever that is easy to do.

Excellent and I wouldn't want to be without it! Was skeptical about this little unit and the good price, but air quality has improved greatly with this, within the first few minutes! I needed a purifier with the negative ions, and preferably also UV urification, though I have two other small purifiers. This has made all the difference. I plan to buy more. Highly recommend!Happiness level is higher, brain chemistry seems better, bad smells in house are totally gone, am sleeping far better and feeling extremely happy and healthy with this around. Even the quiet sleep mode seems very effective!(It had one issue when I first turned it on: a small piece of plastic was stuck in it and made a loud noise, but then flew out of the machine on to the floor, and I've had no further problems!)
