The person that became obsessed with getting it right went this way.  What
they came up with on CG list is called Polyester Filter Felt, comes in 12x1=
2
sheets at a cost of $1.26 each.  It is sold by McMaster-Carr and is part #
6376 T11
Try this to get to themhttp://www.mcmaster.com/ then type in- polyester filter felt 5 microns
Then scroll down page.  I ordered 2 12x12 sheets that I had with in 2 days
at a total cost of $7.77
Polyester Filter Felt
Ideal for very fine filtering of water, organic solvents, organic acids,
petroleum oils, weak alkalies, and mineral acids. Sold in individually
packaged sheets for convenience. Max. temperature is 300  F. Color is
white.
          12" x 12"
5 Micron         Sheets    Sheets
Rating    Thick.    Each    Each
It works very well and seems to be reuseable for ever.

Right.
Anyone wanting a sample of some somewhat different material (food grade,
seared on one side to prevent fiber migration downstream during use), e-mai=
l
me privately. I'm finally getting a couple dozen samples out the door today
to some folks who've been waiting on my lazy butt for weeks, and I can do
another mailing this week.
The 5 micron is indeed the sweet spot. 10 will give you fines. 1 is overkil=
l
and unnecessarily thick.
