DIY CARBON FILTER ROUND 2 so my first filter i made just didnt seem to cut it. maybe it had an air pocket or maybe i had it too close to the fan and it wasnt scrubbing enough. i dont know but i swear i could smell some buds around my house. now i have a big filter, and it is full of 15 lbs of carbon and a total diameter of 3". so i said i have to change i cant have family or some friends know. right, i could get into some shit. so one day i was watching an episode of urban grower and saw this nice carbon filter Rating: 5
