hey guys I was thinking about making this DIY carbon filter Inspired by a friend. The cylinder with the screen around it is a cricket cage I got at walmart for $4. Then I bought the vent filters for $3. I am going to line the inside of the cricket cage with the vent filters. then Im going to fill it with activated carbon, and put something like panty hoes to cover up the hole. then Ill just attach it to the set up with some heavy duty tape or something.
