I bought this 3 in 1 air purifier because I was tired of wasting money on space heaters that broke after a couple weeks of use due to dust and dog hair getting caught in it. This air purifier is AMAZING! The heat feature is better than a space heater along with nice clean air. It has cut down on the amount of dust and dander in my house which means less cleaning ;) The portable remote is conveniently designed and easy to use. I will definitely be recommending this product to others. Thank you Shark!!
