Cardboard will absorb the odor and leak out. Door skins are easy to cut with a utility knife. That's about as thin as you can get. It works better if there is an open space where the blower goes. That way the suction pressure through the filter is spread out evenly over the whole screen.

You got the right idea, props to you.
Zandor Reviewed by Zandor on . Another question for Zandor......... Zandor, i saw a thread a bit back with instructions on how to make your own carbon air filter. If you could run it by me with what materials i need and how to make one i would forever appreciate it. I'm just a student asking for knowledge from the professor. :) Rating: 5
