GRIMNI'S NEW FILTER
Filtering project by grower /u/grimnirreaps.
So from intake to exhaust it is built with Scythe Kaze 133cfm fan, then a 120mm fan spacer (gutted fan), medium sized hole screen, 120mm fan spacer (filled with activated carbon), medium sized screen, Scythe Kaze 133cfm fan. Saran wrap it to make a sealed system. Works great!
