Worth every penny
Color: Black
I was a bit hesitant about purchasing this air purifier because of its size being small and there were very few reviews.After ordering it and getting it in the mail,setting it up was a cinch and it was very easy to put in the filter. It was simple to figure out how the air purifier works without the manual. I turn it up on the highest setting and kept it going everyday for hours and it works without a problem. Immediately the air quality changed dramatically. Within the first two hours after getting it home and plugging it in, the air purifier started to work wonders, the air smelled cleaner, there was less dust and my cat that has asthma had fewer breathing issues. That does not mean my cat does not still have asthmatic issues it just helped her breathing a great deal. Once the filter was ready to be replaced, it was easy for me to find a replacement on amazon.com and I'm very impressed with his air purifier. Also the filter last a while, I had this air purifier going all day everyday on the highest setting and the filter lasted a month and a week. Perfect size for a small room, I mean a studio size bedroom no bigger than maybe a little over 250 sq ft by 200 square feet. Any bigger and it's not going to do much it is not going to work as well . It is a very quiet air purifier. I'm very much impressed with this air purifier and the filter. I will be buying another one in the future. This is an excellent product and I have no negative statements about the air purifier. It's fantastic and worth every penny you will spend. Update 12/2/2019 : Worked fine during the final weekend of November 2019. Then will not turn on. Just stopped working all together. Did not last a year. Worked wonderfully up until last weekend. Still would purchase, that is if the price was still under 45$. Get warranty! ... show more

Nice
Color: White
I really like this for the bedroom, easy to use. You can buy replacement filters. Maybe not “name brand” but they do still make filters that function and fit with these models. Just see filter type and size and look based on that. Or ask Rufus AI option. Easy to move. Cleaner feeling air not so stuffy. I do have animals and really helps with smell as well. ... show more

Pretty good
Color: Black
Smaller than I expected, but still works good. Whisper quiet on low setting, but noticeably loud on other settings. Filters are cheap and available on Amazon.

Has worked like a champ
Color: Black
I've had this filter for almost two years now. It has helped me clear the air in my apartment, and keep it that way. When I moved in there was a strong musty/mold smell from a large closet area. I could not have stayed here if the smell continued, so I did some surface washing and got this filter. I kept it running regularly for weeks. It worked great, and the noise was minimal. At first when I turned it off the scents would return fairly quickly. Now I only run it for a few hours, maybe once a week, and I no longer notice any smell. I particularly like the timer function. There's a timer on it that can be set for 2, 4, or 6 hours. I put it on and forget about it. The only critique I ever had of the filter is that I find the control buttons to be very sensitive, so that it will turn on, then off very quickly with only what i think is a single light touch. It took a little getting used to. That's a minor inconvenience when the filter as a whole works great. ... show more

Decent filter but don't Trust the UV Sanitizer with Your Life.
Color: Black
It does a decent job filtering air in a bedroom. I would get something bigger for a larger area though. The UV sanitizer is not going to clean all the air that moves past it. Its a great idea, but it is not implemented well. Lots of air will move around the UV light and will not be sterilized. This is not going to perform at the same level that the study did because it does not have enough light, it does not expose all the air moving through the filter. In short this is a gimmick. It has not removed all the odors in my room. I have had better luck with an ionizer. Its still worth using for the HEPA filter however just don't expect this product to protect you from dangerous air born pathogens like Covid. ... show more

Small profile. Good fan. Replaceable filter and UV bulb.
Color: Black
Doesn't having an anode like the B-1000 (I also use), but the HEPA filter and UV bulb both have replacement parts. The B-1000's UV bulb isn't replaceable. Nice small profile, fan works very well. California has a ridiculous law that bans some of these kinds of products, including this one.

Use and throw away?
Color: White
What do we do if they no longer sell the filters. Why buy it? Looking high and low to find replacement filters. Great product but its a shame to throw away perfectly good machine because they won’t sell filters for it.
