How to Change BTE Filters

A Step-by-Step Guide for Hearing Aid Users in the UK

Keeping your BTE (Behind-the-Ear) hearing aids in top condition is essential for clear sound and long-lasting performance. One of the simplest yet most effective maintenance tasks is changing the BTE filters. This guide will show you how to change BTE filters easily and safely, step by step.

What are BTE filters and why they matter

BTE filters, also known as wax guards, protect your hearing aids from earwax, dust, and moisture. Over time, they can become clogged, causing:

  • Reduced sound clarity
  • Distorted or muffled audio
  • Feedback or whistling
  • Potential damage to the hearing aid receiver

Regular replacement ensures your hearing aids deliver optimal sound quality and prolongs their lifespan.
