Excellent product in Arizona dry climate

I've had a Vornado 1-gallon tank system for about 5 years, and it works great, but we moved to Arizona. Our house is larger and it's a drier climate, so I ordered the EVDC500. I could tell a difference right away. We have it in a large open space (831 SF). My husband had been gone for a week and came home and commented that he could tell a difference. I was visiting friends for several days and could tell a difference that their home was much drier than mine. It's quiet, no white dust forms, and it's easy to use. I love that it has a feature that automatically turns it off if it runs out of water. I would highly recommend it.

So Pleased!

We recently moved from a house where all the heating/cooling comforts were "piped-up" from the basement through the HVAC system. Low humidity levels became a real problem in our new apartment home when the heating system was started. Having purchased other Vornado products in the past, I ordered this unit to help with the situation - huge improvement once the humidifier was started. I have since ordered a second unit to fully humidify our 2400 sq feet of living space. The Energy Smart feature works well for variable fan speeds and quiet sleeping noise levels. I also appreciate the ease in filling the water canisters and keeping the unit clean.
