We must admit we were impressed with the H7550 pureguardian™ humidifier. The new design is attractive and it includes all of the advanced control settings that you get with the top-of-the line ultrasonic humidifiers that cost almost $100 more. The idea of including an extension wand with the humidifier so it can disperse even mist throughout entire room, or be placed on the floor, was a good thought but lacks in design. When the wand is attached to the humidifier it takes away from the appeal of the humidifier and looks awkward. Despite that one criticism, the H7550 represents a great value for its price, providing advanced controls with automatic operation, no need for replacement parts and a respectable 3-year warranty. This humidifier is a good fit for a small or large room and has the option of warm or cool mist output for optimal comfort.
