This unit replaced, under warranty, an Electrolux 50 pt. unit that died. The Electrolux unit worked great, I could set it to 35 - 40% humidity and it would reach that goal easily. The new unit ran on continuous mode for 4 days and then I set it to 40% and after 2 weeks, it can only reach 50% humidity level. I would not recommend this product.
