RZ M2 Air Filtration Mask - Canadian Woodworking & Home ...
The filter is the most important part of this mask. The RZ M2 comes with an F1 filter that can be easily removed from the mask by unscrewing the two discharge valves. Once removed you can hand wash the mask with warm water. A professional or hobbyist woodworker in a small shop should expect to get from 50 to 60 hours of use before replacing the filter.
