Cerushield V2 Wax Protection

Cerushield Disk V2.0 098-0445 wax guards are third-generation replacement filters developed for Phonak RIC hearing aids. Supplied in 3 sets of 24 (72 total), all units are identical black plastic disks with uniform thickness and central venting. No adhesives, metals, or silicone used — pure thermoplastic construction meeting ISO 10993 biocompatibility guidance. Each filter integrates an advanced hydrophobic and oleophobic surface finish that reduces surface energy, making it harder for viscous earwax and skin oils to bond. This delays saturation and preserves sound port openness. Dimensions conform precisely to Phonak’s published receiver port specs — verified via caliper measurement and functional testing. Designed for ease of use: fits securely with light finger pressure; removal requires no tools. Ideal for self-managed care routines — especially among older adults or those managing bilateral devices independently. Also supports telehealth follow-ups by maintaining stable device output between appointments.
