Phonak Wax Filters & Guards
Phonak receivers use either Cerustop wax guards or the SmartGuard protector, depending on the receiver design. Cerustop also fits Unitron, Widex and Oticon receivers that use the same guard, which is why one pack covers several brands.

Frequently asked questions
Cerustop or SmartGuard — which does my Phonak take?
It depends on the receiver rather than the model name. Cerustop is the widely used guard shared across several brands; SmartGuard is Phonak's own protector for the receivers designed around it. Match the packaging your current filters came in.
How often should I change a Phonak wax filter?
Roughly monthly, and straight away if the aid sounds muffled or has gone silent. If you produce a lot of earwax, weekly is not unusual.
Do Cerustop guards fit other brands?
Yes — Cerustop is used across Phonak, Unitron, Widex and some Oticon receivers. Check that your existing guard is a Cerustop before ordering, since Phonak also ships SmartGuard on some receivers.
