I couldnt be happier with my heater. Heats a large odd shaped room with no problems. Quiet running and does exactly as advertised. Filter is easy to clean with having the ability to adjust the heat with more variable setting is great. This one replaced a first generation EdenPURE. Hardly even a blip on my electric bill. I used this heater to meet the varying demands of a hospice patient. It helped keep them comfortable in a very difficult time. Forget the copycat heaters.Seen them and they are junk.Just pay the money and get quality the first time.I want to also say how happy I was with customer service, great company to deal with. Professional in every way. I would recommend not only this heater, but this company as well.
