How to Build a Mini Carbon Filter & Exhaust Fan


A quick guide on how to build a small carbon filter and fan combo unit with 120mm fans, some activated carbon, and a lot of straws. A quick note regarding this build - after prolonged used of this custom carbon filter I've started taking some of the activated carbon out to improve the overall airflow, down to about 25% filled and have gotten good results still although the activated carbon will need to be replaced more frequently because of this.
