The Kärcher KFI 487 fleece filter bags (part number 2.863-006.0) are designed to keep your vacuum cleaner efficient while collecting both dry and damp debris. Each pack contains four white bags made from a three-layer, tear-resistant fleece that provides a reliable barrier against dust and dirt, replacing the older 6.904-409.0 version. These bags are compatible with a wide range of machines, including the WD 4, WD 5, and WD 6 series, as well as KWD 4-6, MV 4, MV 5, MV 6, and the SE 5.100 and SE 6.100 models. Measuring 260 x 190 x 13 mm, they fit securely into the device to ensure a clean workflow during household or workshop cleaning.
