All our high end HEPA dust filters are tested individually according to the EN1822 norm.
More specifically, the filters are scanned along EN1822-part 4 of the norm. Depending on the filter shape, some of them are tested according EN1822- part 4 Annex A.
The minimum local efficiency and global efficiency of the flat filters are measured.
For special shaped filters, an "Oil Thread Leak Test" is performed on every filter.
This test is based on laser detection.
