type of filter?



hey guys i am planning to shoot my car in my garage and am going to use a couple of 20" box fans to exhaust any overspray/fumes. what type of filter can i use to put in front of the fans that will be placed at the garage bay door??

Over the years, I have done this many of times and if you want a filter, you can just get a 20x20 exhaust filer from a paint store for a couple bucks each or a furnace filter.
If you live close to your neighbors and trying to keep overspray down get the paint store ones.
If you are trying to save the fans, neither filter will, as the fan will still get paint colored.
thanks Barry, not caring too much about the fans theyre only $14 :)
