special air filter

[27143721]

Dear guys:

I am looking for a special kind of air filter which can meet following standard:

1. washable
2. DIN5510-2 ( S4, ST2, SR2) or NFF16101 M1 F1
3. efficency higher than G3 ( EN779)

I know it is very difficult to find, can some one give me a clue?

thanks in advance!

DIN 5510-2: 2001-06 applies to materials which are used in railway vehicles.

Requirements 1 and 3 are easy.
Being a cheap component (few euro a piece), I don't think it even exists compliant to requirement 2.

I have samples here of teflon covered washable G4 filters, so they can be considered compliant to n.1 and n.3.
And no, I'm not familiar with railway standards, I just googled.
