Works beautifully until it nearly explodes!
I started using this in my classroom in Sept. It really seemed to help keep the germs down, as my class got sick far less than our neighboring classes. Yesterday morning, I noticed that I didn't hear the hum when I entered my class. I went to check it, and it was SUPER hot to the touch. The fan quit, after only 2.5 months of use and it was overheating! Thankfully I caught it before it started a fire!
