Does the fan face upwards or downwards?

[@shutupanddoityourself]

The air is blowing away from the filters. If it were the other way the fan would get filthy.

[@David-kj1vm]

why not put one filter on the end of the fan??

[@shutupanddoityourself]

My thought process was if you place one filter over the fan it reduces airflow and will cause the fan motor to overheat. I figured it would be better to have a plenum chamber to create negative pressure.
