City-Flo XLHigh Efficiency Air Filters (EPA, HEPA and ULPA)
EN 1822:2009This new European standard is based on particle counting methods that actually cover most needs for different applications. EN 1922:2009 differs from its previous edition (EN 1822:1998) by inclu-ding the following:
An alternative method for leakage testing of Group H filters with shapes other than panels
An alternative test method for using a solid, instead of a liquid, test aerosol
A method for testing and classifying of filters made out of membrane-type media
A method for testing and classifying filters made out of synthetic fibre media
The main difference is related to the classification for the filter classes H10 - H12, which has now been changed to E10 - E12.
The filter class description are:
EPA 10 - EPA 12: Efficiency Particulate Air Filters
HEPA 13 - HEPA 14: High Efficiency Particulate Air Filters
ULPA 15 - ULPA 17: Ultra Low Penetration Air Filters

Local penetration values lower than those given in the table may be agreed between supplier and purchaser.
Group E filters (Classes E10, E11 and E12) cannot, and shall not, be leak-tested for classification purposes.
