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.

Evap 40

Don't expect to fill it with tap water. It requires distilled water, although is not specified on the description. The owners manual does mention it.


The only problem I have is that it is a little awkward to load the water containers into the main body of the humidifier.


This product works well during the time the heat is not running.I have it in a less than 1000sq Ft room and per my hygrometer,the humidity goes into the low 20's from 50 overnight when the heat is turned on. I have everything on high. I would consider buying another for the room but think that it could be the product since this room size with normal ceiling height should be handled by this humidifier. This room is @400 square feet. The humidifier works fine with the air conditioning.


This has helped me with my allergy symptoms. I have a large bedroom and it works great to create moisture in the air. Ordering was easy and delivery was quick!


Works great!
