OSIMO Small Room Air Purifier with H13 True HEPA Filter for Bedroom Home Office, USB Quiet Desktop Portable Air Cleaner, 3 Modes for Dust Pet Dander Smoke Odor

For the price, it’s an incredible value. It runs quietly, I’ve had it for about 6 months. I purchased another one for my bedroom. I have noticed a reduction of dust, and smoke odors in my living room. I feel like this is a good value for one room use. I have had bigger air filters, rated for small home use. I think it is far better to have two, one for living area, one for bedroom.

I had a horrible smell in my apartment. It just smelled musty and I also have a cat so the litter was a concern. I clean it often but I always felt self conscious that it smelled. I ordered this and have noticed a huge difference. It’s small and lightweight, extremely quiet, I never notice it. Half the time I forget to turn it off. Easy to use and has a sleep mode which is nice but I don’t use it much because I never notice it anyway. 3 speeds and no annoying lights. The only thing I noticed was it collects the dust around the casing of the fan but that’s not an issue. I just wipe it off and it never bothers me. This really helped with my allergies and the smell.

I'd say I have an average sized bedroom, fits a king bed, two dressers, and two nightstands. When i leave for work I turn this on and shut the bedroom door. When I come back the air definitely seems much cleaner. I have left this on over night while sleeping and woke up way less stuffy than normally, which is great. The purifier itself seems pretty tiny, but it works fairly well and it's aesthetically pleasing. Not bulky. It fits in on a night stand or book shelf. It is noisy though. The lowest setting is not too bad, but setting 2 and 3 are noticeable. I don't mind white noise, butttt not every night, so I do not often use it at night. Also, the light on it is SUPER bright, like a green nightlight over my night stand and into my face. I use whatever is nearby to cover it up, like a small box or whatever and that works. Now i could use it on the low setting to help at night, but i do not feel like the low setting would work as well to clear the air. Just my thoughts though.It is a good buy for the price, maybe better in a small nursery for white noise. Or for cleaning the air while you're out of the house!

The media could not be loaded.  I am a freshman at college and I was having a lot of issues with my allergies. I bought this (might I say, amazingly priced) air filter just to see if it would help. I had been having a runny nose and my throat hurt, but after I got the air filter, I was so much better. I plugged it in and let it run in my bedroom for only one night and I woke up and I didn’t have a runny nose any more and all of my seasonal allergies were gone. I was so impressed. This little air filter is small but that doesn’t mean it isn’t powerful. I have left this thing on 24/7 and I never have allergies problems anymore. It was so easy to install, it barely makes any noise (and what little noise is does make, helps me to fall asleep like white noise) and it was so well priced. I know you can spend a lot of money on air filters but you don’t need to because this does the job and does it well. I love having it in my dorm room!So if you are thinking about getting this one, GET IT! It will literally make your life so much better!

I kinda liked this purifier, it's quiet and very energy efficient, and USB-C connection is a big plus! Look good too. But unfortunately, mine stopped working and does not power on anymore, even with another cable.

Nice little air purifier. A bit loud, but does a very commendable job and does not take up too much space on my desk.

I was expecting company and purchased two of these at that time. While both are identical, one of them does cycle through various levels of intensity. It's supposed to have three settings. One of the air purifiers I bought works perfectly. The other one only runs on one setting. I needed them both for the company. I'm not sure that the "one setting" one did much of anything? Even though these are small and quiet, I really do notice a difference in the air the extra bedroom where I decided to keep running it indefinitely. It feels fresh in there.Edited on 10/1/22 to report that the purifier that only ran on one speed stopped working completely. I kept the filter and the cord and tossed the device--it was a lemon from the start. I changed the rating from 4 stars to 2 stars. The other purifier is still chugging along and working well. I don't like wasting money like this. 50% success rate is a failing grade.Edited for the last time on 10/4/22 to report that the "good" air purifier started making a very loud noise this morning and stopped working. For almost two months it did freshen the air in that room, but obviously this product is a waste of time and money and a waste of all of the components that it is made of. There is no point putting out junk like this that half-a*#@ works and ultimately breaks in a short time.

This was actually the third unit that I have purchased and they are all working great. The performance of the first two is what made the selection process for the third really easy. While it is probably not the normal use case, we use them on top of the litter boxes for our four cats. They are awesome at cutting the powerful litter box smell to almost nothing and really quiet. Which the cats, my wife, and I all really appreciate. It did require some modification to the litter boxes to make the filter unit sit securely on top and be able to draw the air out of the box. Completely worth the purchase price and the little bit of effort to not have everything around the litter boxes smell like cat poop. The filter cartridges last us about 5 months of continuous running, but even if we forget to change them they still work decently as far out as 8 months. Would recommend staying within the 6 month suggested replacement cycle.
