ProWax wax filters
ProWax wax filters are used to prevent the earwax from obstructing the Bernafon Zerena Custom hearing aids, thus lowering its performance. It is advisable to change them whenever you notice that the hearing aid gives less power or at least once a month. Checking its condition when doing your regular cleaning task will help you assess whether it is clogged or not and change it if necessary.
The box contains 6 units.
These filters are compatible with the Bernafon Zerena Custom hearing aids, all formats.
