I used it for about three hours in a row. It was possible to use it without suffering intake exhaust even indoors full of dust. The pressure on the face is also a light feeling. It was easy to wash the main body after use.
Work in dust in farm work. Cutting of hay. Rice husk carriage.

It is good that you do not misalign with the perfect face. Filter exchange is also easy ○. It is easy to clean even if it is dirty with sweat. Although the structure of the supply / exhaust valve is simple, it operates reliably and is safe.
I was looking for a product that can be used in combination with a covering surface. This product does not interfere almost without much front frontal area. Intake is light and easy. Also, because it is light weight, it will not make you bitter.
