Cool Mist Humidifier: Features a 6 liter (1.6 gallons) reservoir with a super high mist output. Our ultrasonic humidifier for bedrooms works in rooms up to 500 square feet and lasts 50 straight hours. This makes our air humidifier suited for large rooms and is an ideal room essential for the room, apartment, office, nursery, or college dorm | Essential Oil Tray: More than just a humidifier, we included an essential oil tray. Your oil diffuser humidifier circulates the oils into the cool mist, giving you a clean, pure, and fresh smelling aroma. Now you can create an aromatherapy experience. It also can be used as a humidifier for babies and features a blue LED night light | Auto Shut Down, Quiet: The vaporizer humidifier automatically shuts down when out of water. This helps prevent damage to the unit and keeps you protected. Our home humidifiers are nearly silent (less than 30 DB), making them a suitable humidifier for baby rooms and bedrooms | Filterless Design: Our ultrasonic humidifier design is filterless, saving you from ongoing replacement costs. IMPORTANT: Running the humidifier in humid conditions can cause water accumulation on surfaces. Use a hydrometer to monitor humidity levels. It is recommended to keep humidity between 40 and 60 percent. Exceeding 60 percent humidity can cause water accumulation and can damage wood, and other surfaces | 2 Year Replacement Policy: At Everlasting Comfort we care about your experience with our products.
