Efficient and low maintenance

This is a great alternative to the finicky hot steam humidifiers. Give it a few days and your room will reach the exact humidity you want--the internal sensor will stop the fan after it reaches that. The sponge-like filters that evaporate the water into the air did get red and a bit musty/dirty after 4-5months of use (even using bactericide) they're replaceable which is nice. It's 2-4 days before you have to refill. I would recommend.

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!

Great humidifier- easy to use

I love the simplicity of this humidifier. It holds enough water to run all night on high. Controls are simple and easy to operate and understand. Solid unit that should last a long time.
