OX-ON Mask FFP2NR D w/Valve Basic is the affordable filtering dust mask with valves, which you can use when working with health-damaging, dry particles and liquid aerosols with a limit value >5 mg/m3 (max. concentration 10 x limit value.) You can use a single-use disposable mask when sanding wood, metal, stone, and plastic, for example, as well as when working with lead/copper-free paint and spray painting with water-based paint. The mask is dolomite-tested, which means you get a mask with particularly high dust capacity, where resistance slowly increases. The mask is also equipped with a valve, which ensures good comfort and a pleasant climate inside the mask while you use it. The valve helps prevent accumulation of moisture and heat when you are wearing the mask. Soft foam forms a seal at the nose and a malleable nose clip ensure a perfect and comfortable fit with your face. 20 x masks per box.
