Why I like this humidifier/vaporizer from Walmart

I've owned numerous vaporizers/humidifiers over the years. This one is TOPS! It's easy to fill. The ease of operation is perfect for anyone. Touch control allows me to set the amount of mist so easy. Just slide my finger up or down the slider and the mist volume immediately changes to my touch. I fill it once a day. I use the pitcher from my blender to carry water to it. I highly recommend this item.

beautiful humidifier for a bedroom. Mist is instant and it has an easy control of the rate of.flow. Way more esthetic than the traditional"ugly" ones. And you can add pads of fragrance to help with the congestion or something like lavender to help with sleep.

Powerful, quiet, %26 aesthetically pleasing

Cute humidifier, puts out a lot of mist and so quiet you cant hear it. Just got it, been running about 3 hours and so far so good! I have gas heat and it just sucks any moisture out the air, definitely needed something to be able to breathe. I like the light that you can turn it on and off, and the power/setting is touch, no buttons. Plus no filter. Budget friendly, Im happy!
