Can I setup my exhaust fan to blow into my carbon filter as opposed to having it pull through it?

You may do this, however it is important to pre-filter the air before pushing it into the filter. If you choose to setup your filter this way, remove the pre-filter from the outside of the carbon filter and fabricate to fit before or after the fan. This way the air will be cleaned of larger debris before passing through the carbon, thus prolonging the life of the filter.
