OX-ON Mask FFP2NR D w/Valve Comfort is the safety approved filtrating single-use mask with valve, which you can use when working with hazardous dry particles and liquid aerosols with a Workplace Exposure Limit (WEL) <5 mg/m3 (max. concentration 10 x WEL). You can for example use the disposable mask when you are grinding wood, metal, stone and plastic, and also when working with lead/copper-free paint as well as water-based colour spray paint. 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.
