My filter fan is a 92MM delta fan. PFB0912UHE, Very powerful.
It is throttled by one of these

I added a stick on coper heatsink to the LM2596 chip, and an external potentiometer. Theis bucker loses a volt on the top end, but that fan is so powerful at 11 volts its loss is of no consequence.
The fan uses 4 4 inch deck screws on the intake side, to prevent filter material from getting sucked into impeller. The pan perimeter is covered in narrow strips of velcro to which the carbon filter material sticks.
The fan is mounted to an adjustable gooseneck similar to those designed to hold micrphones. the gooseneck is attached to a 2 inch spring clamp I can clmp in many places throughout my rig and aim the fan where required.
I used a paper stapler to join the carbon filter together to make the 92mm square sock. The sock keeps the filter far from the impeller, and vastly increases the surface area, presenting minimal restriction to the fan.
One cannot simply place a 20x20 filter on the backside of a 20 inch box fan and expect it to move much air, but if one were to move the filter 20 inches away and use more filters on the sides then there would be almost no restriction to flow and much greater surface are for filtering.
