Nilfisk Action A100 and the A200 and the Nilfisk Action A300 in RED Domestic Vacuum Cleaner and the A400 in LIME and the Nilfisk Action Plus in Maroon vacuum cleaner H10 HEPA exhaust pleated paper cartridge filter and the Nilfisk Bravo vacuum cleaner which succeeded the Nilfisk Action Series of vacuum cleaners.
These cannot be cleaned in any way and must be replaced.
Other than what I've written on each of these pages, I have no other information on the difference between the filters.
According to EN 60335-2-69 The Terms "TYPE H" FILTRATION and HEPA FILTRATION are NOT INTERCHANGEABLE
The HEPA classification only considers the "efficiency of filtration" eg H10 H11 H12 H13 H14 U15 U17 NOT the SUITABILITY FOR USE with HAZARDOUS or COMBUSTIBLE dusts.
