I used a $10.00 filter from hardware store, comes with a plastic mesh that I wrapped and wired around exhaust fan. Next I wrapped the charcoal side of the media to the inside and prefilter to the outside. Hope it works, I think it will.

haha, good idea! So funny, I JUST was looking at this filter in the hardware store yesterday, thinking about something similar. I'll be curious to know if it works.
