To protect your investment, daily maintenance is crucial. You’ll want to regularly check and replace filters to prevent earwax-related issues. Our Care guide also provides essential maintenance steps for optimal performance.

Daily 

Check the dome, receiver and hearing aid body. Use a clean wipe if necessary to remove any debris.

Monthly: Dome and filter change 

You will want to replace the dome (speaker covering tips) every month. 

Changing the CeruStop filter 

Your CeruStop filter should be changed when: 

  • You observe that the filter positioned in the mold is obstructed.
  • The hearing aid does not produce normal sound.
