Cool moisture humidifier delivers high output for large areas and features an air-washing pre-filter that helps capture dust, dirt and pollen from the air that passes through it. Quiet Care technology allows the humidifier to be 30 percent quieter than traditional consoles. Independent Humidity Control maintains your preference with three moisture output levels to help temporarily relieve dry air discomforts. Use the tank window to monitor the water level. The humidifier will cover more than one room up to approximately 1900 square feet or an extra-large room up to approximately 2300 square feet.
