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.
Dust work / welding operation

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.
Use it in a dusty work area.

I think that breathing is comfortable as a feeling of use and a fitting feeling is also good. I have not used it for a long time, but if it is this, it is likely to go for a long time
When polishing welding traces of steel, stainless steel, etc.

I use this mask for quite a long period, but because the thickness of the filter case is thin, it is possible to use it even when a welding mask is attached. Especially when using arc, using activated carbon filter can considerably reduce suction of fumes, considerably aided. There is also an excellent effect when using the plasma cutter. It is a little disappointing that rubber string deterioration is considerably early. Is there a rubber string sold separately?

I tried various masks, but I am satisfied with the thickness and the best thickness.

At our company, everything is wearing this work in the factory. Regularly, we purchase in the form of supplementing some ones on cheap day. It will be appreciated if you can make the filter attached to this a little cheaper.
