Introducing the US NIOSH and EN149 standard masks – the respirator mask with double layers of melt-blown filter that meets the US NIOSH filtering 95% standard or EU EN149 filtering 94% standard, which is the most widely recognized standards for daily work protection or industrial use. The cone shape of the mask leaves more breathing room for your comfort, and the nose bridge allows you to adjust the fit to your face. Two head straps provide a secure seal, while the black cushioning nose foam ensures a comfortable wearing experience.
