Bests & Worsts Reviews from Amazon

Pros: Easy to set up Not too loud. Sounds like a small fan is on in the room. I like white noise like that. Circulates air efficiently. Filters air very well. Cons: Expensive air filters (only reason why I took 1 star off the total) Other Comments: The biggest thing I was looking for in an air filter is how much space it would cover. I have a 20'x20' living room with 9' ceilings connected to a kitchen roughly the same size. This keeps the entire 1500 square feet of my upstairs clean. I ran it downstairs where I am doing demolition and BOY does it clean the air up fast when I have it on Turbo. Left it on overnight and it worked like a charm. I can already see the layers of dust in the carbon filter. Sound wise in correspondence with fan speed: Low ( They call it the "Germ" setting ) - sounds like an average fan on low Medium ( They call it "General Clean" setting) - sounds like a fan on medium High (They call it "Allergen" setting) - starting to get a little loud. Definitely cannot watch a movie in the same room with it on Turbo (They call it "TURBO") - What? What did you say? Oh God! It's sucking everything in!
