I was looking for a clean way to heat instead of using our pellet stove. Bought one of these to try it out. LOVED it so much I have 3 of them now! The air is so clean smelling with the purifier and the humidifier is just the right amount and so easy to fill! The remote is Great, works perfect! I live on a slab. I have one in my living room, one in the kitchen, and one in the back where the bedrooms are. You probably are not suppose to, but this is our only source of heat and has been since Sept and it's now the middle of Jan. Depending on the temperatures here in Up North MI, I have been running the heater in the living room with my Shih Tuz's. Mostly on low. When the temp starts to drop I turn the one on in the back of the house also. On low. If the wind is blowing and it's really cold I also turn the one on in the kitchen so I will have 3 running on low. I have a security monitor that I can see the one in the living room when I leave and I can see the red glow to know it's still running. It has a over heat shut off, and tip over shut off. You can set the temp setting. or on off setting to turn it on and off. The temp setting is a little off, but I don't care, it does shut off and on around the setting I put. It's quiet, clean and safe in my observing it. Best heater I ever had which is why I bought 3. Electric heat can be expensive to run so I try not to have all 3 going unless needed. We are toasty warm, the air is perfect and I love heating with these heaters!
