Only Two weeks old, and all ready starting to stink?

Ever think about making an activated carbon filter system?

I made one with a 6" blower fan, then a 6"-4" reducer, before I put the reducer on the 6" blower fan, I stretched some nylon (panty hose) across the inlet of fan, then I placed the reducer over this, I then filled the reducer with activated carbon, I then stretched another piece of nylon over 4" opening. Then I put a 16" tube made of wire over the 4" opening. The 16" wire tube is covered in activated carbon fabric.

Here is a picture of what it looks like.
