For dust field work

When setting the paper filter and the micron filter in a stacked manner, the installation of the filter is hard. Adhesion between mouth and mask is good. I think the breathing is easier as the filter area is wide.
Excluded soot and dust during welding

I tried buying it because it is thin making so that the welding surface does not hit. The filter part is wide and it is easy to breathe, but because the chott is heavy, the mask part will come down unless it is tightened tightly. There is no thing that special use is bad.

I think that it is the best for working in the factory because it is a user-friendly product.
Used for welding operation

Automatic light shielding surface is also cramped, but it is usable. A state hitting inside. Soft, such as mouthfeel, odor is suppressed, no problem with performance. I wonder if it feels a bit heavy until I get used to it. When it was cramped with an automatic light shielding surface, the top of the nose became painful. If you are concerned about odor and dust at the time of welding, you should buy proper things rather than buying halfway masks.
When processing a grinding wheel

Because it is a consumable item, I am purchasing, but the price is also cheaper than other companies, I am satisfied.

The same type that I used before was purchased again as it melted with heat. The fumes of TIG welding are helped because the grain is fine.
Welding operation etc.

If it is tacky, it can be done with a normal cup mask, but in the case of continuous welding etc. exerts outstanding sense of security, Although some stuffy feeling can not be helped, since the odor of Hume drastically decreases, it is safe

I am happy to use it because I purchased it thought that the products of Koken were good.

I want something a little more compact in shape
Various polishing painting work

The adhesion is good, the check mechanism is convenient and secure. Because there is little respiratory resistance due to the wide filter area, we can work comfortably because we can not feel the weight.
