A Review of Variable Speed fan controller

I bought this in order to be able to control the speed of the Fantech Whole House Hepa Filter. You plug it into the wall and then the fan you want to control, into the unit. You turn the dial up and down to get the speed you want - very simple.

It has a nice plug so no need to wire anything yourself. User friendly. Cheap and does the job it's supposed to do. I got mine very inexpensively from Amazon.
