Review on ULTTY Bladeless Tower Fan with Air Purifier - True HEPA Filter, 99.97% Smoke Dust Pollen Dander Removal - Oscillating Tower Fan R21, Black - Remote Control included by Sophia Sanchez

I would give five before it stops working. This fan has been in operation for three (3) weeks. In the third week I turned it on one night and it wouldn't come on. While it worked I thought it was great when I bought it for my 6 year old room. He had an allergy and it seemed like a great product until he died. I don't know why it doesn't work but I'm very disappointed because I was willing to buy two more for the other bedrooms in my house.
