The PureGuardian H4810AR is a 120-hour ultrasonic humidifier with a large 2-gallon tank capacity, ideal for medium to large rooms up to 600 square feet. It features both warm and cool mist settings to optimize comfort in different seasons and conditions.

This humidifier utilizes ultrasonic technology to silently disperse a fine mist into the air, making it virtually noise-free and perfect for use while sleeping. The tank is treated with Silver Clean Protection, which fights the growth of mold and mildew on the water tank surface for cleaner, healthier operation.

The electronic control panel offers three speed settings, a soft-glow LED night light, and an automatic timer that can be set for 4, 8, or 12 hours of continuous operation. The dual-direction mist nozzle allows you to rotate the top section to broaden mist distribution throughout the room. An optional aromatherapy tray accommodates essential oils to create a relaxing atmosphere. The low water indicator illuminates when it's time to refill, and the unit automatically shuts off when the tank is empty for safety. Dimensions are 12.5" H x 7.75" L x 15.03" W with a 60-inch power cord. Backed by a 3-year limited manufacturer warranty.
