Customers are saying

Customers love the Ultrasonic 2 Gal. Warm and Cool Mist Aromatherapy Humidifier for its large tank size, quiet operation, and ease of use. Many appreciate the adjustable mist settings, overall performance, night light, and timer features. While refilling can be a challenge and the unit is heavy when full, users are happy that there are no filters to worry about.

    My son was sick over the holidays so we picked this up hoping it would help. It definitely did! We have ran it nonstop for 3 weeks now and it's great. The water reservoir lasts about 2 days. When we walk in his room there is a fresh feel in the air. We are considering getting 2 more for the house.

    We absolutely love our Pure Guardian Ultrasonic Humidifier! We purchased the product because our dog had been coughing and weezing and this has seemed to help him considerably. He hardly does that at all anymore and I truly believe that it has benefited us as well.
