The Mirka 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 (Mirka code 8999100811) is necessary.
