Don't buy this heater. It's no different than the cheap ones you buy at Walmart. It has two settings. The low is quiet, the high is very loud and noisy. I returned because it gave off a chemical smell which irritated my sinuses and caused a headache. It won't heat more than a small room. It's way overpriced. I paid $86.44 for the unit. I had to pay to ship it back by UPS which cost $14.93 and they deducted a $9.95 restocking fee. I lost $24.88 on this deal. DO NOT BUY THIS HEATER!!!
