"Thanks to CONAIR or the free Air Purifier. When I opened the box setting it up was really easy. All I had to do was connect it to the devices back plug it into the wall and use the pad to turn it on.. Since its white it matches any kind of decor. It makes a sound, to a fan but doesn't make much noise at all. Specifically for my bedroom I bought this unit because my four dogs spend a lot of time there and things can get a bit sometimes. Honestly within 20 minutes of plugging it in I could already notice an improvement, in the air quality.
