I have been so excited to use this product and it has livened up to the standard so far. I use this in my apartment in the kitchen/living room area. It is great for filtering out smoke from the kitchen and any dust coming from the living room also. Having the screen give you live feedback about the air quality and adjusting the fan speed accordingly is an awesome feature. I have not tried out the heating element yet but with winter approaching I'm sure it will work awesome as its little own space heater in a way before having to crank the heat up to much!
