Hearing Aid Cleaning & Drying Technology

This guide explains how to clean, dry and maintain hearing aids using safe, clinically recommended methods. It covers moisture removal, wax cleaning, UV-C hygiene, vacuum systems and daily routines for better sound quality and device longevity.

Keeping hearing aids clean and dry is essential for performance, clarity and long-term reliability. Earski provides premium hearing aid dryers, UV-C hygiene systems and precision vacuum cleaners for New Zealand and Australia, engineered to support both rechargeable and battery-powered hearing aids.

Why Hearing Aid Hygiene Matters

Hearing aids face constant exposure to:

  • Moisture from humidity, sweat and weather

  • Wax and skin debris that block vents and receivers

  • Dust and dirt from everyday handling

  • Condensation inside charging cases

Without proper hygiene, this can lead to:

  • Muffled or distorted sound

  • Intermittent performance

  • Weak microphones

  • Charging faults

  • Corroded battery contacts

  • Expensive repairs or replacements

A consistent hygiene routine protects your investment and keeps your devices performing at their best.
