What micron filter for cold brew?

Hi all,

Anyone know what micron size to use for a filter bag with cold brew?  I'm done with using the tiny paper japanese tea filters, old socks and undies, chux and various other types of material.

Going to visit a supplier that has reusable liquid filter bags in larger sizes; the ones they put into stainless steel pressure vessels for chemical filtration.

Just thought it would be nice to have some idea of the micron size to make sure I get the right bag..

Your best bet is to do a two-stage filtration.  First pass at 100 micron, second at 25.  The finest silt is like 40 microns.

The one I made a year or so back was just muslin and it works fine. Tiny bit of sludge but far less than plunger. Herbies Spice rack is a possible source or Spotlight etc.
