Watch out - This is a good system, and I can recommend it. however notice in the description when purchasing it describes it as a 6-pack of filters. this is erroneous. it is one filter only.

Excellent air cleaner! - After 1-2 months of usage(portable air purifier), it is very clear that it does a great job, in addition to our furnace air filter!

Clears The Air - Excellent product! Works extremely well, but a little too pricey. Price per filter should be under $10.00.

Great product, filter availability/price a problem - We ve been running two of these units at home for six months now. The amount of garbage they pull out of the air is amazing. The unit is reasonably quiet on setting 2 and much too loud on 3. I m not sure it is moving enough air on setting 1 to accomplish much.The only disappointment is the high price of the filters -- if you can find them. Online sources are much more reasonable, but availability seems spotty. I m hoping this will improve moving forward.
