The 90-Hour Ultrasonic Cool Humidifier guards against problems caused by dry air in the home. It is ideal for use in small and medium-sized rooms. Unlike other humidifiers that grow slimy on the water tank surface, Silver Clean is embedded in the tank to fight the growth on the surface of the water tank. Thanks to ultrasonic technology, it disperses a cool haze into the air, and is ultra-quiet making it ideal to have on while you sleep. This top fill humidifier has an optional aromatherapy tray so a few drops of essential oil can be added to create a relaxing atmosphere. The humidifier is equipped with a night light and variable haze control. A low water indicator light lets you know when it's time to refill the water tank. PureGuardian humidifiers create a better home environment for those suffering from colds and dry skin. Note: Runtime is based on running the unit on low speed, also depends on atmospheric conditions. PureGuardian aromatherapy oils are not included and must be purchased separately. Do not add oils to the humidifier tank as they can damage the humidifier. Only add essential oils to the pad that is included with the unit. Additional essential oil pads are available separately.
