The cartridge filter is designed for a seamless switch between dry and wet vacuuming without having to replace the filter. Thanks to the smart mounting system, you fit and remove it quickly with a twist, so you don’t waste time while cleaning and can focus on the result.

The filter effectively captures dust and fine particles, contributing to a cleaner environment and easier appliance maintenance. It is intended for compact, cordless KÄRCHER wet and dry vacuums and selected cleaning (extraction) models of the SE series.

• No swapping between modes — switch from wet to dry vacuuming without changing the filter.

• High dust retention — reliable filtration for cleaner results.
• Wide compatibility — WD 1, WD 2, WD 2 Plus, WD 3, KWD 1, KWD 3, SE 4001, SE 4002.
