Pros: Great product so far. I use this air filter in my bedroom as my three cats won't sleep anywhere except on my bed, and a lot of pollen gets into the bedroom from the open door from the bedroom to the adjoining outdoor balcony.

I'm impressed with the air filter - my room is at the upper limits of the manufacturer's suggested room size that the filter will work. My allergies (sneezing and runny nose) have decreased by half and aren't as severe as they were prior to the air filter, and I haven't had any problems with my asthma either. The air also seems to smell fresher in the room.

Setting up the air cleaner was easy and didn't take very long, plus it arrived within mere days of being ordered. When it's running at night, it's very quiet. Highly recommended.

Cons: I haven't encountered any so far, but as the air cleaner only works for small rooms it is best suited for those in apartments and condos. This air cleaner might not be effective in a larger place.
