I personally like to put the carbon in a carboy, and shake periodically
for a week or two. I then have a filter like yours. I just fill it a
few inches, and pour the polished spirit through at maximum flow rate.
The reason for the second step is that a short carbon column is an
excellent filter for the loose carbon in the carboy. You don't even
have to pour all the carbon out of the carboy, just decant off, as much
as you can, then rinse with a bit of water, and decant again.
It is a simpler time saver that uses your current equipment.
By the way, a stainless steel screen (such as a splatter screen)
attached to the end of a 2in copper pipe is a great filter tube
requiring no plastic. You can simply cut a 21/2 in circle of stainless
screen and pound it on the end with a 2 inch copper union.
I support the pipe on a bicycle work stand. It is like a huge retort
