KARCHER HEPA FILTER REPLACEMENT
Filter even the finest dirt, including pollen or allergy-triggering particles with the HEPA hygiene filter (compatible with VC 6 Cordless & VC 7 Cordless devices). Removed from the air reliably and safely, it is so efficient that the vacuum cleaners exhaust air is cleaner than the ambient air. For maximum efficiency, we recommend replacing the filter once a year.
