Does what it says
So far I'm very pleased with this unit. It's in my 11 month old son's room and the air stays fresh even when it's time to change the bag in the diaper trashcan. I do want to note specifically that many reviews mention how loud this unit is. While I can certainly hear it (it's by no means silent) it's but a faint hum and not at all intrusive. Unless I'm trying to listen to it, I forget it's there quickly.
