Hopefully, I saved you some headaches at annual
Hmmm. Now things start to make sense. If one externally filters to the same particle size as the internal screen (the 32/35 mesh requirements noted earlier in thread) then the internal screen will never catch any debris. No need to check it.

In the vans std setup, the AFP is a coarse screen so the EX5 screen may pick up debris. I'll keep cleaning it for that reason. Thanks for the info!
