Pros None for me.
Cons Noisy. Night light too bright. Hard to clean. expensive filters.
Summary I couldn't sleep with all the noise, even on low, and it didn't make any improvement in the humidity level in our bedroom. The night light was way too bright lighting up our bedroom all night. It also has filters which you have to buy, adding ongoing expense. Cleaning all the parts will become a problem. We used ours one week and didn't have to add water...when we decided to take it back there was still water in it. Obviously it was defective.
