Flat filter Kärcher KFI 4410

The flat filter located in the cartridge can be changed quickly, conveniently, and without coming into contact with dust: simply fold the filter out of the cartridge, insert a new one, and close the filter cartridge — and it's done!
Other practical features: flat filters for water and vacuum cleaners from the WD 4–WD 6 series allow both wet and dry vacuuming without having to change the filter and interrupt the work.
