It does not get in the way

Weld surface (even on a fogging surface) Working with this mask can not be an obstacle. However, in my case, I had a feeling of strangeness unless I had to tighten the tightening to a certain extent. For this reason, the back of the neck hurts.

In order to improve the adhesion at the time of wearing, we are daringly not using the knitting. I do not mind the smell, I do not have other colleagues or rough skin, including me.
Normal work relatively dusty dancing

Long-selling items you have been using for a while. The filter is purchased from a place cheaper than MonotaRo (a real shop of tool size sale), but MonotaRo is cheaper than the mask itself. It is attractive that other company's products can not leak test at the time of installation.

I am using it for many years, but this type of mask is the best. I work with two kinds of filters. I am saved because masks and filters can also be purchased together.

If it is not this mask, it will collapse with the fume gas generated at the time of welding.

It was saved because we could ship quickly after placing an order.

I think that it is easy to breathe and is good.

I use it everyday. The mask is a life because a lot of dust is dancing. Made by Shigematsu, the shape of the silicon surface will collapse immediately, but the product made by Koken does not collapse even if it is used for one year, it will be in close contact. I check the back side of the intake valve when changing the filter, but I use it with confidence because there is no trace of dust penetration.

Because the area of the air intake is large, breathing is easy. Because the filter is thin, I wonder if it is suitable for disinfection.
