      I bought the Keystone Gray Humidifier to help my indoor plants stay happy during the dry winter. I was looking for ease of use, AND style, to be placed in my living/dining area of my updated 50’s ranch style home. My plants are happy and so am I! The only drawback is that the gray is actually more of a brownish gray, as it looks in the photo. I was actually hoping the color was not too gray, and I am pleased!
