As soon as we opened the box we were impressed with how easy it was to set up. There was a QR code on top and we could figure out anything that wasn’t obvious to us. The heat and fan are such a great addition to an air purifier. The dial is easy to read a tells you just how bad or good your air is. It also gives you the room temperature. At first it smelled “like hot plastic” but after a few days that smell went away. We love that it oscillates also. We didn’t realize how bad the air was in the basement but the shark air purifier 3in 1 cleaned it up quickly. Very uncomplicated remote and easy to use.
