The HoMedics Warm/Cool Mist Ultrasonic Humidifier (Model UHE-WMT365) provides visible warm and cool mist to add moisture to your air, helping relieve dryness so you can breathe easier and sleep better. It features a 2.0-gallon top-fill water tank that is easy to clean and fill, providing up to 120 hours of humidifying mist for extra-large rooms up to 607 sq. ft.
Built-in UV-C technology reduces bacteria, mold, and fungus in the mist, including E. coli, Staphylococcus epidermidis, A. niger mold, and P. citrinum fungus. The programmable digital humidistat with smart auto-adjusting humidity sensor lets you easily set and maintain your ideal room humidity in 5% increments from 35% to 55%. Additional features include a 260-degree dual mist nozzle, five adjustable mist settings, auto shutoff when out of water, auto-off timer programmable for 4, 8, or 12 hours, night-light with on/off switch, clean reminder, and whisper-quiet operation.
The unit is designed for corners and tight spaces, measuring 43 in. x 9.25 in. x 15.16 in. Package includes the humidifier, instruction book, 3 essential oil tray pads, demineralization cartridge, and 2-year limited warranty. Clean Tank Technology helps protect the tank from mold and mildew buildup. For best results, use distilled water to prevent white dust accumulation from minerals.
