Signia QuickGuard Filters

The new QuickGuard Filters from Signia replace the HF 4 filters for custom-made earpieces.

The filter actively prevents liquids from reaching the receiver and thus protects the electronics. This protection is achieved by the nano coating applied to the QuickGuard.

The number of filters in the new packaging is 8 pieces. Naturally, the size of the QuickGuard is exactly the same as the HF 4 filter.
