Absolutely love this air purifier! I bought two, one for my room and one for my daughter's bedroom. I was absolutely floored over what these picked up out of the air! NO WONDER our allergies had been bothering us so much. We are a pet free home, but a very dry, windy, dusty climate. I've had them for about 10 days and have already cleaned the filters once, and they will need it again soon! Thank you so much for this amazing product. Added bonus that it doubles as a white noise machine on high at night time! Sleep mode, which turns the light off is the perfect environment for sleeping in my opinion!
