Changing the wax filter on Philips HearLink

How to tell the filter is blocked and how to change it, step by step.

Good to know

1. The filter stops wax from getting into the speaker. A blocked filter can cause weak or distorted sound.
2. Use only the same type of filter you received with your hearing aids. If in doubt, ask a professional.
3. On HearLink 50 / 40 / 30 models the filter is MiniFit, and the same applies to the MicroShell earmould.
4. On behind-the-ear hearing aids, the filter is in the speaker or in the earmould.

Changing it, step by step

1. Take one replacement tool out of the box. The tool has two pins: one empty, and one with a new filter.
2. Push the empty pin into the old filter in the speaker, and pull it out.
3. Insert a new filter with the other pin. Remove the tool and throw it away.
