"EU rating" of filters

[Speedy]

Could someone please tell me where I can get info on the "EU rating" of filters.
I don't work in the HVAC area, so forgive my ignorance!

Camfil published a technical write up regarding air filters which gives you detailed efficiency test procedures and filter classification based on various standards.

A link about filter efficiency calculation is here,

A good paper on cleanroom classification (if you are interested),
