The anatomical half-mask BLS Zer0 series offers maximum protection while maintaining exceptional breathing comfort. Excellent transpiration properties result from the high water vapor permeability of 4500 g / m² * 24 hours. This value characterizes materials with the highest transpiration range, intended for use in heavy physical work.

Inhaling nanoparticles (particles with a diameter of 1 to 100 nanometers) is dangerous for the human body, because due to their size they are able to penetrate directly through cell membranes, which can cause permanent damage. Specially developed tests have allowed us to design a filter material that effectively blocks the penetration of nanoparticles. Thanks to NANOFILTRATION, BLS can provide a new standard of protection against ultrafine dust.
