This little air cleaner works really well. I bought it to help keep pet odors down around the litter box. So far it makes a noticeable difference in air quality. Definitely worth the $10 I paid. I placed it to filter approx 190sq ft of home instead of the recommended 60 sq ft and it still does a good job.

I bought this little guy about 2 years ago for my husband & his allergies. About an hour after I plugged it in, I noticed a difference in the air quality. Our bedroom felt much cleaner than before. The dander & dust- gone! You will notice a fresher "feeling" when you use this plug mount air cleaner. You can buy replacement filters for this item, but I rinse the filter out, dry it, & use it again. Also, this air cleaner provides a very small amount of white noise- which we like when we're sleeping. Purchase with confidence. Strong enough for one room only.
