Food for thought... On building mine [way back], I placed the fan directly on the rear [centered on the box/bin] and towards the bottom of the box - Thereby making the 'draw' at the bottom and off the piece I was shooting [no overspray or 'kick-back' or 'roll-over' from within the box]. Filter material were simple furnace/HVAC filters, from your hardware store; doubled or sandwiched, and depending how much spraying done these would last for sometime. The filters were secured with simple wire coat hangers cut and bent to fit and with some tension applied, to hold them in place inside the box/bin [easy-peasy to replace and pull filters]. The fan box, its mounting hardware and materials [made from scrap frame material], were all sealed with HVAC/ducting metal tape, from the hardware store...Making for a near 'air-tight' seal with everything. And as to using a bathroom exhaust fan [mine being an 'open frame' 110/120 v AC motor], I never experienced a 'flashback' or 'flash-over' during some 25-30 yrs of usage; even shooting MEK - Acetone - Toluene mixes [HOWEVER - A dry chem fire extinguisher was always near during painting operations, just in case].
I hope this may help in your build/design.
