Waterproof Oilproof Wax Guards

Each wax guard measures approximately 3 mm in diameter and is made from durable plastic material. The pack contains 3 individual filters, designed for precise fit and reliable protection. These guards feature a nanometer coating that delivers effective resistance to earwax, dust, grease, and moisture — without compromising sound transmission. They are engineered specifically to protect the sound port and receiver horn of hearing aids, preventing clogging and preserving acoustic performance. Ideal for daily use in varied environments including humid or dusty conditions, they help maintain consistent audio clarity and reduce maintenance frequency.
