Since it is a chemical hypersensitivity, it is always used

There was no stickiness around the mouth in the cup type. Easy to talk It was good without breathing suffering, but when you use all day because thin rubber on your ear is used, headaches are painful. I wish I could adjust the length of the ear rubber, I wish the width could be widened a bit more ...
I think that it is good for patients with mild hypersensitivity and sick house because it becomes a mask of activated carbon type. Rather than fitting to the mouth, I think that there is no breathlessness or difficulty in conversation because it is a mask of a feeling to fit while securing a space around the mouth. In the case of physical labor, the breathability somewhat falls due to perspiration, but I got the impression that the easiness of breathing becomes easier than the soft mask that fits into the mouth of the general. However, depending on the degree of manual labor as well, an acid-deficient headache also occurred, so maybe this area may be the eternal task of the mask. However, it is a great advantage that you can secure a space around your mouth as you say many times, so I think that breathability and feeling are completely different than other masks when sweating with physical labor.
