Vornado EV100 Evaporative Humidifier


The Ultra1 ultrasonic humidifier from Vornado provides true whole-room humidification. It features Vornado's signature Vortex Action that propels moisture into rooms up to 900 sq. ft. in size. Most ultrasonic humidifiers only break water into microscopic particles and don't project it throughout the entire room, causing the area around the humidifier to be damp or wet. With the Ultra1 humidifier, the Vortex Action feature creates a powerful stream of air that quietly and efficiently delivers humidity throughout an entire room, creating a comfortable atmosphere. It's large-capacity, 2-gallon water tank provides for hours of operation between fillings, with a 3.5 gallon output per day on its highest speed setting. The Ultra1 has simple, easy-to-use push-button controls that allow you to set and maintain your desired humidity level and fan speed. Includes a manufacturer's limited 5-year warranty and 1 mineral cartridge.
