Does nothing.
I have used plasma air purifiers for years and believe they are the absolute best for allergy sufferes. I wanted something small for a tiny room, 5'x6', in my home that doesn't get good air circulation. The room isn't damp, nor is it dirty. The air was just stale and my larger plasma unit cleans it great in a few minutes, but is too big for the room. I put this one on high and left it in there for two hours. Nothing changed, nothing at all. For right at a hundred bucks it should have done something. Luckily it is a prime item, so it's going back tomorrow.
