I already had two of these. during the wildfires from Eaton and Pacific Palisades I bought another one. I can't say enough about this air purifier. the air in your house smells clean instantly. plus it's low profile which I appreciate. I have two other brand air purifiers that are so huge they are an eyesore. I will stick with this one every time it's on sale

Finally Smoke Free

My husband is a lifelong smoker, and although he doesn't smoke in the house, the smell still seeps in from our attached garage. It's been on my mind to get an air purifier. I bought this one to help freshen the air during the winter when I can't open windows. The very first day I noticed a big difference. Right out of the box all you do is plug it in. The controls are simple, which I love. It runs quietly and does the job. It is attractive, as well.

This has been a game changer. My family got the present of Flu B for Christmas. With all the coughing going on I decided it was time to try an air purifier. It has not disappointed. Quiet, easy to use and was delivered in a few hours with Walmart . Highly Recommended. I liked that I can get whatever type of filter I want allowing me to have some decision making in my air purifier rather than being stuck in one mode only.
