Description of Vornado EVAP40 Evaporative Humidifiers

Place the Vornado Evap40 evaporative humidifier in your living room or large open area to create a more comfortable, humidified living space. Many customers prefer evaporative humidification as it will never allow too much moisture to be emitted into the air. Vortex action from Vornado utilizes a fan with deep pitch blades that pull large volumes of dry air through its two humidifying filters, and then circulates the humidified air back into the air and throughout the room. This system of circulation provides uniform humidification in spaces up to 1,000 square feet. The Evap40 features a manual, built-in humidistat with an easy-to-use control panel which allows you to choose your desired humidity level and fan speed. A huge 4 gallon capacity two water tank system can humidify up to 4 gallon of moisture per 24 hours. 5-year manufacturer warranty.

If you are tired of having to fill your humidifier with water every day, the Vornado EVAP40 humidifiers is a simply designed evaporative humidifier that holds 4 gallons of water which means less filling and more humidity. We recommend this for larger common areas since it has an area capacity of about 1,000 square feet. On the lower speeds, the EVAP40 can be refereed to as whisper quiet operation. The humidifier is easy to clean and the water tanks are spill-proof with easy lift handles for comfortably transporting to the faucet.
