Okay, about filters

I am planning my very first grow and I'm trying to come up with a design for my box. I want to add in a carbon filter and i've searched far and wide trying to find out if it would work with the filter enclosed in my box.

I was thinking of having the filter, then the fan, which would then expel the old, cleaned air out of the box. So in other words, the fan would be pulling the air through the filter instead of pushing it through. Would that work? Because when I think about it, it doesn't seem like it would be as powerful as the fan pushing the old air through a filter situated outside of the box.

Any help would be appreciated!
 
pulling air = better than pushing.
