>>66815depends heavily on the particle size
if you are chiseling and carving stone by hand outside you dont need anything crazy
if you are sawing, grinding, cutting, etc and producing dust, then you need an air filter and dust collection and a mask tbh
for wood if you work by hand, you can cut, saw, drill, chisel, etc and you dont need a mask. the moment you use powered tools though you need dust collection and air filtering and sometimes a mask
i built a shelf outside today and the dust was so bad i had to walk away after every cut and wait for it to settle. this was with a breeze too
