HEPA filter for Dust Extractor

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 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 is necessary.
