I have that carbon filter fan. And Unfortunatly it will not be enough to move the air in and out of your box. Look at some 5 inch computer style fans to move air in and out of your box. I use that little fan inside the box to hide a bit of the smell it works pretty good, It can also be used to move air around in the box

But to be totally honest I can fart and move more air than that thing.

good luck
