## Long description

Replacement vacuum cleaner filter bag Karcher 6.904-212.0 is a single white polyester dust bag designed for compatible Karcher wet/dry vacuum cleaners such as NT 25/1 Ap, NT 35/1 Ap and NT 35/1 Tact. Manufactured from woven polyester, the bag captures fine dust and particulate matter while allowing airflow to maintain suction performance. Supplied as one piece, this disposable bag is intended for routine maintenance and dust containment to help keep the cleaner operating efficiently.
Advantages
The polyester construction offers good particle retention and durability compared with paper alternatives, reducing the risk of tears during use. The single-bag design makes replacement straightforward and hygienic, containing collected dust for easy disposal. The bag’s fabric allows sufficient airflow to preserve suction power while trapping fine debris, helping to maintain long-term cleaner performance when changed regularly.
Suitable for
Dust and debris pickup in workshop and light industrial environments
Routine maintenance of Karcher NT 25/1 Ap, NT 35/1 Ap and NT 35/1 Tact vacuums
General wet/dry cleaning tasks where a disposable dust bag is preferred
Key specifications
Material: polyester fabric
Colour: white
Quantity: 1 piece
Compatibility: designed for select Karcher wet/dry vacuum cleaner models
Function: disposable dust and particle capture
How to use
Switch off and unplug the vacuum cleaner before opening the tank or filter compartment. Remove the full or used bag from the mounting collar, taking care to avoid dispersing dust. Fit the replacement polyester filter bag onto the bag holder or collar until it is secure and the sealing edge is flush with the mounting point. Close the tank or filter cover and restore power. Replace the bag when capacity is reached or airflow is noticeably reduced to maintain optimal suction.
Usage recommendations
For best results, inspect the bag before installation for any defects. Change the bag regularly according to the amount of debris collected and the manufacturer’s maintenance schedule. Do not use damaged bags. When cleaning fine or hazardous dust, follow relevant safety guidance and local disposal regulations.
