I chose this because it was recommended on the Popular Mechanics list of some of the best dehumidifiers, and it was less expensive than some others.  I ordered 4 for 3 bedrooms plus the open common area of our humid Florida home which has a mold problem.
This dehumidifier includes a hygrometer, and gives setting options such as Auto, High & Low.
(I have to contact Wayfair because I'm not sure they all work equally.  We were emptying the water on two so often, yet not the others.  I just switched locations to test whether it's the location or the machine.)
