How To - Carbon Filter
Heres my 2 cents.
I've made 2 scrubbers in the last few months. one 4" & one 6" using depot line fans. I used simple fencing wire (rabbit wire) along with some weed blocker material (used in landscaping, they sell large & small amounts) for the screen sections. For the inner cap, just duct tape it over, and the outer cap use a .89c 8"-10" flower pot base. Then the cost is really just the fan and the charcoal.
Whether you are pulling the stinky air through the scrubber and then out or pushing it through and then out, the result is the same, clean stink free air. Think about it, the stinky air has to pass into the fan ducts' airflow one way or the other....
A little side note is that the carbon for a larger unit will run about $40-50 depending on the store. You'll need roughly 10 pounds for the larger unit. (4-5 28oz bottles-Petco, $9.99)
