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

Old classification
These filter have to be verified at least with statistical methods (EN1822-5:2009).
New classification
When you use Camfil Farr products you have the guarantee that our filters fully comply with the latest European standards.

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.
