Wax guard filter Hf 4 and Hf 3 

Well tHougHt-out concept – easy To use 

The HF 4 and HF 3 wax guards reliably prevent cerumen, dirt or moisture from penetrating the hearing system via the 

receiver opening. HF 4 and HF 3 therefore provide the best protection and ensure a long lifespan for the hearing system. 

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 

PracTical: 

The HF 4 and HF 3 wax guards are available in the tried-andtested 

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.

Benefit for you: attractive, problem-free additional business.

THe DeFINITIVe Benefit 

 

 

 

The hf 4 wax guard is Much sMaller Than The hf 3 wax guard. 

This ProVides crucial adVanTages: 

In-the-ear 

hearing 

systems 

 

can be more effectively customised, which is a major benefit for customers with deman- 

ding cosmetic requirements. 

 

The smaller wax guard means the 

vent can be enlarged. 

 

 

 

 

This allows you to perform even 

more open fittings with our in-the-ear hearing systems and impress your customers 

 

 

with greater wearer comfort and better acoustic features.
