OX-ON Mask FFP1NR D Basic is the safety approved filtrating single-use mask, which you can use when working with less hazardous dry particles and liquid aerosols with a Workplace Exposure Limit (WEL) <5 mg/m3 (max. concentration 4 x WEL). You can for example use the affordable disposable mask when working with cardboard, textiles, feathers, graphite, clay, pollen, grinding of aluminium, plaster and quartz-free stone. The mask is dolomite tested, which means that you get a filter with a particularly large dust capacity with slowly increasing resistance. The sealing soft foam rubber at the nose as well as the mouldable aluminium nose bridge ensure you a perfect and comfortable adaptation to your face. The elastic band of the mask is latex-free. You get 2 pcs. masks per box.
