The Istek foldable half-mask respirator, an FFP1 NR class device with an exhalation valve, provides reliable respiratory protection in environments containing harmful substances. It effectively filters out various aerosols (dusts, mists, and fumes) of animal, metallurgical, and mineral origin, as well as dusts and powdered fertilizers that do not release toxic gases or vapors. This respirator guarantees respiratory protection up to 4 times the maximum permissible concentration (MPC) of harmful substances, retaining at least 80% of airborne contaminants.
