This is a fantastic air cleaner. I'm a heavy smoker and it certainly does the job making the house smell nice. I am very happy with this product. Easy to set up, it has very beautiful nightlight which is 2 brightness setting and even turn off. Nice Build quality, filters have a nice firm fit and very easy to change. I like it so much definitely will get another one for my living room. I love that it has 2 year warranty too.
