PureGuardian Ultrasonic Warm & Cool Mist Humidifier

The PureGuardian H4610 is a 120-hour ultrasonic humidifier that delivers both warm and cool mist to improve comfort in medium to large rooms. Its large 2-gallon (7.57 L) tank provides extended run time between refills, making it ideal for overnight use and all-day humidity control.

The unit uses ultrasonic technology to quietly produce a fine mist without the noise of traditional fan-based humidifiers. Silver Clean protection built into the tank helps inhibit the growth of mold and mildew on tank surfaces. The control panel features dedicated buttons for power, mist level (Low, Medium, High), warm mist mode, a programmable timer (4, 8, or 12 hours), and a night light, giving users precise control over their environment.

The H4610 is designed for tabletop placement and operates silently enough for bedrooms, nurseries, and living spaces. The top-fill or removable tank design makes refilling straightforward, and the unit is compatible with optional aromatherapy features.
