A dirty wax filter for hearing aids is the most common cause of poor sound quality—but fixing it is simple! If you're unsure or need to stock up on genuine amplifon hearing aid filters, you can request an appointment with one of our specialists across Australia.

A hearing aid wax filter, also known as a wax guard, is a small, disposable screen located in the tip of the device that sits inside your ear canal.

The wax filter for hearing aids is a critical protective barrier that prevents earwax, moisture, and debris from entering the internal speaker (receiver) of your hearing aid. If this filter becomes blocked, sound cannot pass through correctly, leading to muffled or quiet sound, or even a complete loss of function. Regularly replacing this filter ensures your hearing aid continues to deliver high-quality, clear sound.

The frequency of filter replacement depends on how much wax your ear produces and how often you wear your device.

We generally recommend checking your wax filters every month and changing them approximately every 4 to 8 weeks, or immediately if you notice a significant drop in sound quality. If you have particularly moist or waxy ears, you may need to change hearing aid filter more frequently, perhaps every two weeks. When in doubt, always replace a blocked filter to keep your BTE hearing aid performing optimally.

Using genuine, high-quality filters designed for your specific behind the ear hearing aids is vital for sound performance and warranty protection. You can purchase hearing aid filters directly from any of our Amplifon clinics across Australia. The specific type of wax filter for hearing aids you need depends entirely on the brand and model of your device (e.g., Phonak, Oticon, GN Resound). We encourage all clients to visit a clinic during their next ongoing care check-up to ensure they have the correct supply.

Our service commitment doesn't end after your fitting. Routine maintenance, like knowing how to replace BTE hearing aid filters, is a key part of the Amplifon Way.

We stand behind our devices with superior expertise and dedicated ongoing care to ensure your hearing aids always enrich your life. If you find the replacement process tricky, or if changing the filter doesn't fix the sound issue, it’s a sign to seek professional help. Your device may need a deeper clean or recalibration.
