Recently got this air purifier and so glad I did! We use it in our room and we’ve noticed how fresh it seems to always smell now. There is no setup required, and it is super simple to operate and not very loud...I sometimes even forget it’s on. It has a convenient timer for different shutoff times and a few fan speeds. It also has three different settings for a night light feature as well. It does have a replaceable filter that’s very easy to get to. Overall very happy with our new air purifier!
