I bought this air purifier that has a fan and heater and it is really great. The air purifier has a large filter to keep the air pure for a long time. There are numbers on the purifier that give you a temperature readout as well as an air quality readout. A remote control is included so you don’t have to get up to change temperature or turn it on or off. You do need space for this purifier. It is a good size unit and can’t be placed up against a wall or furniture. The device is fairly quiet and we enjoyed the white noise it provided throughout the night when we were sleeping.
