I was pleased to pick up this device for our bedroom. We have a dog, and our doors are open often. This means we likely have to deal with dirty air! I put it in my bedroom and use it at night. It does go through water quickly, and refilling it is a bit of a chore. That being said the results are great. I also like the sound it makes at night, almost like a gentle sound machine. Clean air is always good, and I feel fresh in the mornings.
