pressure side filter is to trap particles.  

 Suction side filter must be fairly free flowing, more so if there's
no low pressure supply pump.  Restriction on the suction side makes
for aeration and dry pumps pretty easily.  Even with low pressure
supply pump, filter media shouldn't be too fine.  But there should
still be something there to trap small pieces of grit and protect the
pump.

In essence.

Well in that case, get very loud and repeat "I don't care what you
say, I'm right."  It has worked for me... : )
