Phonak and Unitron MicGuard Microphone Hearing Aid Filters
The MicGuard is a microphone protector fitted to some Phonak and Unitron Nano and CIC hearing aids and designed to improve reliability by shielding the microphone from skin debris and ear-wax.
When required the MicGuard may be easily extracted from the hearing aid using the forked removal tool supplied, replacement is a simple push-fit.
Please ensure that your hearing aid is already equipped with replaceable MicGuards as this feature is not available on all Nano and CIC hearing aids.
