I usually use the 631 series with activated carbon, but it is more breathable than I thought it was different from 631, I did not feel breathing. However, as you may sweat, the breathability is still dull and you may have a headache with a lack of acid so sweat and breathing easiness can be said to be the eternal task of wearing a mask at the time of physical labor It may be. It might be a difference whether you take acid lack or tolerance of solvent odor if you are sick house with physical labor or severe hypersensitivity people. However, since this mask itself is not a feeling of fitting to the mouth but a feeling mask that secures a space around the mouth a little, I think that it is suitable for working sweating such as physical labor.
