Works Extremely Well Without Leaving White Dust

We've been really happy with this Vornado Humidifier from Walmart. It works great, puts out a good amount of moisture, and the biggest thing for me is that it does NOT leave white dust or residue all over the furniture like some humidifiers do. I also really like the large water tanks because they're easy to fill and don't need constant refilling. The room feels much more comfortable, especially at night, and it's been easy to use and keep clean. Definitely worth the purchase so far!

Does its job well!

It does a good job at keeping my just over 1600 sq ft house at a good humidity range. It is a little noisy when the glugging sound starts as it refills, but that's to be expected and a decent trade off for the large size of the tanks and ability to use tap water. Overall I'm happy and would repurchase.

What's not to love? Everything about this VORNADO EVAP40 humidifier is perfect. Sorry, i don't know how to send pictures, otherwise we would. We have over 1700 sq ft . and now, our inside humidity stays in the low fifties. Meters are placed in furthest area away from each other. Our only problem is US -- we are in our 80's, in wheelchairs and when these are loaded we are unable to lift out of sink onto my lap to take to the humidifier. So, we fill half-way, PROBLEM SOLVED. We've only had this up and running for a week and already seeing a difference in our skin - less itching; and every day less %26 less dry skin flakes on our floors and furniture. We are so excited to see, with time, what else is easier for us. We are expecting less cleaning of everything - i.e., ceiling fans, return vents, etc., etc..... We could keep on and on but i am old, i am tired and i am now going to take a nap because i don't have to be cleaning instead anymore. Oh yes, thanks for asking for our review, only wish i could be shouting it from the roof top.
