Wax Guard Filter with Nano Coating 3.0

The Signia NanoCare is a small filter element that sits directly in the earpiece. Here it ensures that foreign bodies, dirt or moisture cannot penetrate the earpiece membrane. This is because anything that has once penetrated the earpiece remains there. The result is a significantly deteriorated transmission of the signal, a muffled sound or a total failure.


NanoCare is inspired by nature. Known as the lotus effect, it effectively protects against dirt and is water repellent at the same time. In this way, you ensure that your hearing instruments sound flawless. At the same time, you reduce the susceptibility to repair.


Wax Guard filters should be replaced approximately every 4 to 6 weeks. The small grid in the filter should always be clearly visible and free of debris during this time.


Wax Guard NanoCare 3.0 are the matching filters for the new Signia 3.0 receivers. For the miniReceiver 2.0, please use the tried-and-tested Wax Guard cerumen filters.
