The right filter for every application
Depending on the workplace and the noise exposure, the optimal filter is selected in consultation with a hearing care professional – ranging from 15 dB to 31 dB. Hörluchs® HLFs filters are water- and dirt-resistant, replaceable, and – depending on the model – come with special certifications such as W, X, S, or E1.
This ensures the SOWEI provides the best possible protection while maintaining speech intelligibility in the workplace.
