HELP! Which filter to use, other than PES?

[Jorde]

I'm a little confused on what filter to use for conversions I know PES is the best but in my country I am limited to whats available, but we have:

Polycap 36 AS Nylon Filter
SFCA MEMBRANE
cellulose nitrate
Cellulose Acetate Membrane

Can someone elaborate on these and what is next best to a 0.2um PES membrane?


Thanks
