Abstract: A tool for replacing a cerumen filter in a sound conduit of a hearing aid. The tool is designed to position a cerumen filter along the sound conduit and to couple with and remove a cerumen filter that has been positioned along the sound conduit. The tool comprises an insertion tip and an removal tip, both configured to fit inside the sound conduit and to couple or engage with an engagement body extending centrally from the cerumen filter. The tool may be in the form of a stylus with the insertion tip on one and the removing tip on the other end. The tool may also be in the form of a disc dispenser with a plurality of insertion and removal tips attached to the dispenser and accessible for use by rotating plates making up the disc dispenser.
