Abstract

Abstract A cartridge-type filter having a filter element (12) and first and second endpieces (14, 16) between which the filter element is sandwiched. The filter element (12) is formed as a strip of filter material having a plurality of folds (204) and its ends may be connected together to form a loop. The filter can be economically assembled by using hot-melt-adhesive films (18, 20) for bonding the first and second endpieces to the filter element. The endpieces are preferably formed of material sufficiently flexible in their main dimension that the filter shape as projected onto either endpiece can conform to differently-sized receptacles.
