No pictures of the step by step but this is a no brainer.

It's just a wood box about 24�x18�x36� where you have air drawn in through the top with a furnace return grill about 16x20. Next you get 5 medium quality filters the ones with screen mesh on one side are the strongest. You can use 5 to 10 pounds of active charcoal from the fish store for each layer. You make a charcoal sandwich and use gray tape to seal the sides and make it one big thick filter. You build the box so the filters fit tightly on all sides. You have a stop of about ½� trim all around the part where the filters end so you can keep them in place and tight but do not restrict the air flow through the filter.

Next you have a 12â?� air gap between the bottom of the filter sandwich and another plywood sheet you attach the high volume fart fan (bath room fan) to the underside. This is about 18â?� from the top going down overall measurement. You should have about 18â?� of empty space for the return air to fill so you drill 2â?� holes along the bottom of the box for return air back into the room.

The idea is to pull the air through the filters clean the air with the coal and return the clean air back to the room. Mine is in the ceiling and has a duck return system back into the room. You need to build the same thing but in a self contained wood box. I like this design better then the cylinder version it's easer to keep fresh and reuse for many years.

Happy building
