Product review (5 stars): This is a great humidifier for my 1000 sf condo
This is a great humidifier for my 1000 sf condo.  I've always used the smaller units which eventually get very grungy and are impossible to thoroughly clean.  I end up throwing them out.  This appears to be easy to keep clean because of the filters and the recommended solution I put in the water.  The best part is the fact that you are not constantly filling up the tank.  Easy to maintain.
