What You'll Need
- A dry cloth
- A cleaning brush
- Spare domes
- A pack of wax filters (white packet)
- A pack of microphone filters (green packet)
Step-by-Step Cleaning
Step 1: Remove the Dome
The dome is the soft rubber tip that sits on the speaker (the part that goes in your ear). Hold the speaker end of the wire between your fingers and gently pull the dome off.
Step 2: Wipe the Dome
Wipe the dome with your dry cloth. Domes block up with wax easily, so try to do this every day, ideally before you put your hearing aids in each morning. A wax-free dome lets clear sound come out.
Step 3: Change the Wax Filter
The wax filter is a small guard on the speaker that stops wax getting inside. Replace it using the white packet of filters.
- Open the white pack and take out one of the black rods.
- Each rod has two ends: a removal peg on one end and a brand-new filter on the other.
- Push the removal peg end straight into the old filter on the speaker. It should pop in.
- Pull the rod away to remove the old filter.
- Turn the rod around and push the new filter straight into the speaker. Go in straight rather than at an angle, or the filter won't sit properly.
Step 4: Change the Microphone Filters
Each hearing aid has two microphones, one at the top and one at the bottom of the processor (the main body that sits behind your ear). Both have filters. Replace them using the green packet of filters.
- Open the green pack and take out a green rod.
- Each rod has a short end, which is the removal peg, and a long end with a new microphone filter on the tip.
- Push the short end into the top microphone filter. It should stick in.
- Pull the rod away to remove the old filter.
- Turn the rod around and press the long end onto the microphone to insert the new filter.
- Take a second green rod and repeat steps 3 to 5 for the bottom microphone.
Tip: if you're unsure where the microphones are, push the short end of a rod into each microphone and leave both in place. That shows you exactly where each filter sits.
Step 5: Brush the Outside of the Speaker
Use the brush from your kit to clean the outside casing of the speaker. Wax often sticks to the surface, and moisture from the wax can damage the speaker over time.
Only brush the outside casing. Don't brush into the filter, as wax from the brush can transfer into it and block the sound.
Step 6: Put the Dome Back On
Push the dome back onto the speaker using the small hole in the dome. Give it a light tug to make sure it's secure.
How Often to Clean and Replace Parts
- Wipe the domes: Every day
- Change the wax filters (white packet): About every month, or more often if you produce a lot of wax
- Change the microphone filters (green packet): About every two months
- Change the domes: About every three months
