CeruShield Disk is a Unitron unique wax protection technology that is exclusively compatible with Discovery receivers.
Every Discovery receiver has a CeruShield filter installed within the receiver tip.
When the hearing aid loudness or sound quality is lowered, or if the receiver spout appears unclean, we recommend replacing the CeruShield filter.
Each CeruShield Disk features 8 fresh CeruShield wax filters and 8 worn filter locations.
