    As workers' health and welfare are becoming increasingly important, there are needs for protecting workers from being exposed to dust particles in workplace. One of the simplest ways to protect workers is to wear a one-time-use mask of the 3M type. Although conventional masks are convenient to use, they provide low filtration efficiency simply because of air leaks through interface between the face and the mask. In this study, a new type of mask is developed and tested. The air which is filtered first using high efficiency particulate air(HEPA) filter is supplied to the nose area of workers' face. The developed mask was tested for filtration efficiency and for workers' acceptance. Very good results were obtained for both accounts.
