This is the. best humidifier in its class. I bought it for my 2 bedroom basement. This beast can suck moisture atleast 2 gallons in less than 3 hours. It has good capacity water bucket very huge compared to others so you dont have worry about pouring it so often. My experience has been great so far.All I have worry about to keep it running in optimum operation is to make sure you clean the filter when the machine tells you and clean the water bucket with warm soapy water and that's it. Lastly, it is truly the best energy saver, it draws on about 3 amps 275 watts so I can run it all day without having to worry about spike in my electricity bill. All in all, I am so happy with this buy and I am glad I did my research and it paid off. [This review was collected as part of a promotion.]
