Review on KeySmart CleanLight Air XL Purifier by Rose Sanchez

I first bought this for our home and was very happy with the results. Then I bought one for my daughter because she said she was always full when she woke up in her dorm room. Now she wakes up clearly. A small hint. Check your filter from time to time. They recommend changing the filter every three months (which makes sense) but my light came on after a month and when I opened it there was a small piece of lint on the surface of the filter. I removed it and the sensor returned to normal. .
