Pros:
-Top Fill design: many people underestimate how important this feature is when buying humidifiers.
-Great Capacity: It holds almost two gallons of water in quite a compact design.
-Warm/Cool Operation: The warm setting really gets the steam going at almost twice the rate of the cool option. Lots of "smoke" like an old steam train! It is not a space heater though, but it does get quite warm.
-Quiet Operation: the unit is very quiet in cool mode. When used in warm mode, you hear a "bubbling" sound like boiling water.
-Slick Design: it is a very good looking unit. I much prefer the black color over white. The control layout is very modern looking and super easy to use...plus it comes with a remote control. Very large digital screen with huge characters.
Cons:
-Hygrometer Accuracy: I find the built-in hygrometer to be inaccurate most of the time - at times it reads up to 10 degrees off. Highly recommended to buy a separate hygrometer to get a more accurate reading of the humidity in the room.
- Warm mode consumes water twice as as fast as cool mode (this is expected). Keep this in mind when using warm mode at night because it might go through an entire tank of water in one night if you live in a very dry environment.
Overall, this is an excellent unit. Highly recommended.
