    Works beautifully as a purifier and love the auto setting. However it does not play nice with humidifiers and will run constantly even if the humidifier is brand new. (Purifier is across a 700 sq ft room from the humidifier).

    It has been running for last 3 weeks and I have noticed a slight improvement in the air quality. It is situated in the living room but still filters out and eliminates smoke originated from the kitchen several feet away.
