Protect your respiratory tract against harmful and toxic dusts, fumes, and aerosols with the Moldex 3408 Air Plus ProValve reusable dust mask, engineered for demanding FFP3 protection. The pleated filter design dramatically lowers breathing resistance, allowing you to breathe comfortably and work without premature fatigue. An integrated ProValve exhalation valve vents warm air and minimizes moisture buildup inside the preformed cup-shaped shell. Thanks to the washable tpe face seal, you can easily clean and reuse the mask across multiple shifts. Passing the dolomite clogging test ensures long-lasting airflow, making this respirator ideal for heavy construction, demolition, concrete grinding, and metalworking.
