* Required Fields



What Is It?

  • Dial of 15 blue or red HF4 wax filters

What Does It Do?

  • These gauze-based filters are acoustically transparent and prevent cerumen (wax), dirt and moisture from penetrating the hearing aid via the receiver opening at the end of the hearing aid. In in-the-ear, and receiver-in-the-ear hearing aid designs, the receiver is the electronic component inserted the deepest into the ear canal, and therefore should be offered the most protection.

Can Be Used With:

  • These are commonly used in a number of manufacturers in-the-ear products, particularly Siemens and ReSound
  • HF4 wax guards can be easily taken out and exchanged using the integrated changing tool.
