When to change domes and cerushield wax filters on a Phonak Audeo P90? What is the criteria for changing them.
DOME: Obviously one would change the dome if it was torn or if it easily comes off. It seems like mine could go on forever, but I did change them after 3 months as Aud recommended this, but it seemed wasteful. Currently cleaning: daily, brush off, very rarely brush off with alcohol wipe (if dropped).
WAX FILTER: The cerushield wax filter is a little more confusing because I’ve been told to change it when you notice a change in hearing and/or every 2 to 3 months regardless. Apparently the Cerushield disk can be in need of changing but the user may not be able to tell.
Current care: I was told by one aud to NOT remove the dome, just brush off as needed and by another to REMOVE the dome. So I’ve been removing the dome nightly and brushing off as needed. I also lightly brush off around the receiver (just the very outside tip really) - have never really found anything there.
Your thoughts?
