Siemens HF4 Filter – Wax Protection

Siemens HF4-Filter (Pack of 15)

The HF 4 wax guards reliably prevent cerumen, dirt or moisture from penetrating the hearing system via the receiver opening. HF 4 therefore provide the best protection and ensure a long lifespan for the hearing system.

The HF4  wax guards are available in the tried-and tested round dispenser and in the classic colors red and blue.
The wax guards therefore also make it easy to distinguish between left and right hearing systems.
The wax guards can be very easily taken out and exchanged using the integrated changing tool.

The wax guards offer crucial benefits:

• Maintenance-free
• Practical and easy to use
• Robust
• Good value for money
• Distortion-free with up to 90% soiling
• In the case of extensive soiling, muffling indicates the need to change the wax guard
• Acoustically transparent
