HF4 Pro Hearing Aid Wax Guards Filter Kit – Red & Blue Earwax Traps Replacement (15 Filters/Dial) for Custom ITE, ITC, and CIC Devices – Fits Siemens, Signia, Resound, Phonak (2.4mm/2.5mm - NOT HF3)

• Please note that these are HF4 wax filters and are not compatible with devices that require HF3 filters. HF4 filters are the smaller, micro version in this series, measuring approximately 2.4mm in diameter, whereas HF3 filters are larger (around 3.0mm). Because of this size difference, they are not interchangeable—the HF4 will not fit securely in a device meant for an HF3. Please check your hearing aid's manual or your current filter packaging to ensure your device requires the smaller HF4 size before ordering
• UNIVERSAL HF4 COMPATIBILITY: Designed to fit a wide range of custom In-The-Ear (ITE), In-The-Canal (ITC), and Completely-In-Canal (CIC) hearing aids from major brands including Siemens, Signia, ReSound, and Rexton.
• COLOR-CODED FOR EASY IDENTIFICATION: Features the industry-standard color coding—Red for the right ear device and Blue for the left ear device—ensuring a mistake-free replacement process every time.
• MAXIMUM RECEIVER PROTECTION: The fine mesh grid acts as a highly effective shield, preventing earwax (cerumen), dust, and moisture from entering the delicate sound port and clogging the receiver.
• EASY INJECT/EXTRACT TOOL: Each dial wheel comes equipped with a double-sided application tool. One end features a threaded tip to effortlessly pull out the old filter, while the other holds the fresh filter for seamless insertion.
• RESTORES OPTIMAL SOUND QUALITY: Regularly replacing clogged wax guards prevents weak or distorted audio, instantly restoring crisp sound clarity and extending the overall lifespan of your premium hearing instruments
