Bolsa filtrante de fieltro Karcher KFI 657 (compatible, MPN 2.863-371.0) para varios aspiradores Karcher

Fleece filter bags Karcher KFI 657 are replacement dust collection bags designed for use with a range of Karcher vacuum cleaners. Manufactured from a multi-layer fleece material, these bags trap fine dust and larger debris to protect the vacuum's motor and internal components while helping to maintain consistent suction performance during routine cleaning tasks. The design supports straightforward bag replacement and helps keep the dust canister area cleaner between services.

Advantages

The fleece construction offers effective particle retention and reduces the risk of clogging compared with coarse textile bags. The bags are shaped to fit compatible Karcher vacuum inlets securely, minimizing dust escape during removal. Their disposable nature simplifies maintenance and avoids the need for frequent filter cleaning, and the material provides reliable airflow to preserve suction power over the bag's usable life.

Suitable for

• Routine household vacuuming on hard floors, carpets and rugs
• Workshop cleanup of sawdust and small debris (non-hazardous)
• General-purpose dust collection where disposable bags are preferred
• Users seeking easy bag changes and consistent filtration performance

Key specifications

• Material: multi-layer synthetic fleece for fine dust capture
• Compatibility: designed to fit a range of Karcher vacuum cleaner models with matching inlet design
• Capacity: standard disposable dust bag volume suitable for household and light workshop use
• Filtration performance: retains fine dust particles to protect motor and internal filters
• Design: single-use bag with secure inlet collar for quick replacement

How to use

Switch off and unplug the vacuum cleaner before opening the dust compartment. Remove the full bag by detaching it from the inlet collar and dispose of it according to local waste regulations. Insert a new fleece filter bag by aligning the bag collar with the vacuum inlet and pressing it into place until it seats securely. Close the dust compartment and restore power. Replace the bag when visibly full or when suction performance decreases noticeably.

Recommendations

For optimal performance, combine these fleece filter bags with properly maintained motor and exhaust filters. Avoid vacuuming sharp objects, liquids or hazardous powders with disposable fleece bags. Store spare bags in a dry place away from direct sunlight to preserve material integrity.
