Phonak and Unitron have two different types of wax guards. These CeruShield wax guards are made for the Phonak 4.0 receivers. They work with the Marvel, Paradise, and Lumity receiver’s.
If you have earmolds you need the CeruStop wax guard for the end of your earmold and the CeruShield for the end of the receiver.
These wax guards help you keep your hearing aids clean, moisture free, and working great. They are easy to replace on your own!
