Amazon Customer: Bought it early in 2020 as an accessory for my small retail shop to ward off the virus from the front purchase counter where a lot of older men (my shop's usual clientele) who are most vulnerable can feel safe. Anything I can do to relieve their anxiety and reduce the possibility that my shop is spreading the virus is a necessary expense. While I don't have any empirical evidence to it's effectiveness I can say that it is worth the price just point out that it is there and purifying the air that they are breathing. Use it as a point in my advertising as a way we are contributing to the elimination of the virus through cleanliness, even of the air that is breathed.

B on Maui: 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.

Sasha H.: I have three cats that spend most of their time in my bedroom. I purchased this to circulate fresh air and help contain pet fur and dander. It is easy to set up. I like having three speeds with the option to turn UV-C Sterilizer on/off, including the sleep timer/function. The lowest speed is quiet and becomes louder as you turn the speed faster.

I've been using it for a little over two weeks and my room smells fresher. I also noticed less pet fur in my room when I sweep/vacuum but wish it could remove more. If you want a portable purifier, this fits the bill. If you want a purifier that will do a better job removing pet hair, you'll have to look into something larger.

Guinevere Freeman: 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...
