Indoor Carbon filter mounted in wooden box

[newtogrow]

Thought about this a bit to much so want to run it past fresh brains to make sure it makes sense, I have to small rooms both about 3 x 3 x 6 feet want to use a carbon filter on both but don't want to buy two filters if I mounted a larger filter in a custom made air sealed box with two feeds in and one feed out for the fan do you think this would work I've taken in to account loss for the duct run. Looking at a 6 to 8 inch fan and filter and then twin 5 to 6 inch ducting to each of the rooms. I would love input on this matter

Rough plan

==duct==[fan]===(filter) ====== twin inlets

Hope that makes sense lol
