Phonak Cerushield Wax Guards for Phonak 4.0 Receiver
Phonak Wax Guards are used to protect the delicate Phonak ex earpiece 4.0. Change the small filter regularly to prevent foreign objects from entering the earpiece and to ensure that your hearing aid always has a flawless sound.
We recommend changing it about every 4 to 8 weeks.
 
The Phonak Cerushield filters are in a round dispenser box, with an integrated removal tool. When you want to change the filter, insert the receiver into opening 1, where there is a small pin that pulls the old filter out of the receiver. Apply only very light pressure when replacing the filter. Then remove the new Cerushield filter on the opposite side.
