DIY Bud Dryer

i have seen plenty of diy bud dryers on the internet. they all provide step by step instructions which is good, but when it comes to building a carbon filter for it, there are no intructions. can someone please point me a link or provide me a step by step process of making a diy bud dryer including how to make the carbon filter for it. thank you, i have just harvested the clone only the white and this girl is stinking up my whole house.. please help somebody anybody

thanks solar guy but how do i attach this to the bud dryer? do i attach it to the inline fan or what? do u know where there are pics of how it is attached so that i could use that as a guide?

yes inline fan on either end, pulling air is easier than pushing tho
