Abstract
In this paper, we report the performance of dust respirators using the high-performance resin wool filters (Mighty-Micron Filter and Uni-Micron Filter) followed by the national certificate examination. The developed resin wool filters showed a high efficiency for the collection of NaCl particles and DOP oil mist having various size distributions. Furthermore, the efficiency for the collection of oil mist was maintained for a long period compared to that of the former filters. Our filters are usable in various applications as high efficiency filters as well as dust respirators.
