The HEPA (High Efficiency Particulate Air) filter can be
installed in addition to the standard filter to improve the
filtration. By adding this filter you will get a triple
filtration: 1. Fleece dust bag 2. Standard main filter 3.
HEPA filter. Please note that adding this filter will not
make a dust extractor DE 1230/42 an H-class extractor,
even though the filter itself fulfills HEPA class H13
requirements. When installing a HEPA-filter for the
first time, the HEPA Filter Cover for DE 1230/1242
(Mirkacode 8999100811) is necessary.
