For airflow would a filter be better placed prior to or after the main fan?
I am looking to build a very simple air filter setup to help reduce dust and cat particles in the air while deep cleaning. Would I be better off putting the filter on the front side (air out) or back side (air in) of the fan. I know to keep dust off of the fan itself the back may be better but will i get better air flow with it on the front? Thanks for any info.
