Frit size?

Looking to get a fritted buchner funnel from Stony Lab on amazon. They sell ones with fine (15-40um pore size), medium (40-80um pore size), and course (80-120um pore size) frits. I expect I’ll mainly be using it with a bed celite, clays, AC. Would pore size even matter then? Is there a significant difference in flow rates b/w the different frit grades? Should I find one without a frit to make cleaning easier? Thank you.

15-40um will be the one you need. Celite will pass though medium pore size probably
