ditto on this design!

but I have a somewhat relevant question:

with THIS SPECIFIC FILTER DESIGN in mind

Would one be able to use a 120mm computer case fan with CFM rating of 103 to effectively pull/push air thru and get deodorized air on the outside?

or a sturdier inline fan of similar CFM is required?

we're talking $20 vs. at least $80 in cost.

and FYI, for purposes of this post, the venting system will only be used to deodorize the air without actually having an exhaust outside of the closet box (no attic, outdoors, wall connection), aka enclosed air filtration
EDIT: THIS FAN QUESTION IS NOT FOR PURPOSES OF HEAT CONTROL
