FFP3 filter class provides protection against all particulate matter, smoke, and water- and oil-based mists/aerosols. The mask is equipped with a Klima exhalation valve. This minimizes exhalation resistance and prevents condensation from forming inside the mask. Combined with the ActivForm seal, the user will enjoy a secure and comfortable fit. The Moldex 2555 dust mask retains its shape thanks to the Duramesh outer shell. The headband is easy to adjust, ensuring the mask remains comfortable on the face for extended periods.
