I went to the section at Walmart where they have small fans back by the spray paint. The fan was $11, it is a 3 speed. I got the plastic storage box where they have the aisle with all of them. Came home and measured the diameter of the fan and cut a circle the same size on the back of the box. Cut it out with curved tin snips. Found a couple areas on the fan outer edge where I could run a screw with no damage to anything. I held the fan inside the box and ran a couple self tapping screws thru the back of the box into the edge of the fan to hold it. I put the fan on speed #3 since the control is no hidden inside the box. It now turns on and off by plugging it in.
I did screw some wood to the inside of the box to place the filter against, but duct tape could hold it just as good. I cut the top in half to cover the fan area and leave the painting side open.
Bear in mind that duct tape could do everything the screws did, a glue gun could do the same thing. It isn't heavy and nothing here requires serious holding power. The most important thing is to seal the filter to the side of the box 100%. You can just place another filter in front of the solid mounted filter for your first filter level. This is the filter you will replace every now and then.
I'm not good at written directions, but I can draw some pictures if you need some more detail.
