Kärcher - Membrane filter, NT 30/1, NT 40/1, NT 50/1

Enables vacuuming without a filter bag: The additional membrane filter made from non-woven fabric is easily pulled over the container on our machines in the Tact and Ap range. As a result, the majority of different types of dust is pre-filtered in the membrane filter, effectively protecting the main filter. Made from synthetic material that can be washed and reused.
