At Amplifon, we offer trusted expertise to simplify your device's upkeep. Knowing how to replace ITE hearing aid filters quickly and correctly ensures your advanced hearing aids deliver optimal sound every day. If your device is muffled or silent, the filter could be blocked. If you'd like a clinician to help you or would like to get new filters, get in touch with your local clinic.

In-the-Ear (ITE) hearing aids place the speaker (receiver) directly where earwax is produced.

The wax filter is a small, disposable guard that protects the sensitive electronic components inside your ITE, ITC, or CIC hearing aid from earwax, moisture, and debris. Without a clean filter, earwax will block the sound outlet, leading to muffled or intermittent sound, or even permanent damage to the receiver unit. For tiny models, like completely in canal hearing aids (CIC), this guard is absolutely vital.

The deep, custom fit of ITE aids means they are exposed to more earwax than other styles.

We strongly recommend replacing your ITE hearing aid filter immediately when the sound is blocked, or as a routine preventative measure every 2 to 4 weeks. Due to the high risk of blockage in the ear canal, custom-fit devices often require more frequent filter changes than external models. Check the filter weekly for visible wax build-up, especially if you have an active lifestyle or produce a lot of earwax.

Replacing the wax filter for hearing aids on ITE models is straightforward and requires the specific applicator stick provided with your replacement filters.

Follow these steps, working over a stable surface:

1. Preparation: Wash your hands thoroughly and ensure you have the new filter pack.
2. Identify the filter: Locate the sound output hole on the tip of your ITE hearing aid. The old filter will be visible inside this hole.
3. Use the applicator stick: Open the new filter pack. The applicator stick has two ends: one pointed end for removal and one end with the new, clean filter.
4. Remove the old filter: Insert the pointed (removal) end of the stick straight into the centre of the blocked filter. Gently pull the stick straight out. The old, dirty filter should be attached to the stick.
5. Insert the new filter: Turn the stick around. Insert the end with the new, clean filter straight into the now-empty opening. Press gently until the filter sits flush with the hearing aid surface.
6. Complete: Remove the stick and test the device. The sound should now be crystal clear.

Using the correct, manufacturer-approved wax filter is non-negotiable for the performance and lifespan of your custom in-the-ear hearing aids.

You can purchase Amplifon hearing aid filters and wax guards directly from our Amplifon clinics across Australia. The specific type of filter (e.g., CeruStop, HearClear) depends on the brand and model of your device. If you are unsure which filters you need, simply contact your nearest clinic.

ITE, ITC, and CIC hearing aids are highly sensitive and can require more frequent professional cleaning than external devices.

We provide superior expertise and comprehensive ongoing care to ensure your technology never lets you down. If you follow the steps to change hearing aid filter and the sound remains unclear, it’s time for a professional clean.
