that would work good for the screens in the video i posted, but he is going to want to push that air through more than just a thin filter.Go to the Hardware store, or Walmart, and get a furnace filter. Arm and Hammer and some of the other MFG's make activated Charcoal 'odor eliminating' Furnace filters for homes with pets & smokers...
Remove the cardboard & wire and flatten it out--- cut it to size and for about $10-12 you have a years worth of filters you can change every month!
