This is a beautiful piece of machinery. Simple lines, easy to use and quiet. Filter is easy to get to, color display is easy to read. Very satisfied with purchase.
So far I'm very pleased with the unit. The lifetime warranty gave me peace of mind for the future. I like the features of the color wheel to know when the air is being cleaned and the fact that you can turn all the lights off when I sleep. I have noticed a difference of my head not being so stuffy when I wake up. All in all it seems like a very good unit.
