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.
