Furthermore, you can for example use the 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. At the same time, this quality mask is provided with a valve, which ensures you great comfort and a pleasant climate in the mask when you use it. The valve helps to prevent the accumulation of moisture and heat when wearing it. 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 10 pcs. masks per box.
