Putting together a Rubbermaid style cab I used what I had available to make a easy carbon filter.
Two matching planter bottoms that are a little smaller than the bottom of a five or three gallon bucket
Fine mesh, enough for two pieces a few inches larger than bottoms
A desk fan, I toke the base off - cut out the top of a five gallon bucket and attached with zip ties
Five gallon bucket
Fit desk fan into lid of bucket…pic 1 & 2
Cut out approximately five inch holes in each of the planter bottoms and one the same size in top of cabinet. I used plumbing adhesive and drywall screws to fasten one of the planter bottoms to the top of cabinet. Pic 4 & 5
Place mesh screen over planter bottom, pour in enough activated carbon to make even ˝ inch layer. Put second piece of screen over top, push down planter bottom and fasten two together with drywall screws. Pics 6, 7 & 8
Trim any excess mesh and set bucket on top of planter bottom carbon filter..
