Rust removal before steel frame stairs
From Japan
On 2017-09-10 01:23:15
Although I am using it several times, the contact part with the skin of the face deteriorates to oily and it becomes rash. The other parts are firm. I do not know why. I also order new ones.

Compared to competitors' products, gaps between cheeks and nose are difficult to open. I mean, I feel like fitting.

It is surely collected from the mask. I am saved because I can breathe easily.

Measures against dust when using Thunder
From Japan
On 2016-06-08 08:29:13
Removal of dust is powerful, but if you leave it for a long time with sebum attached to the rubber part in contact with your face, the rubber part will be in a situation like melting. Does not it manage?

I will use it when I am performing dust work occasionally.

Although it used it last time, periodic replacement is necessary because it becomes easy to inhale outside air when the exhaust valve becomes brittle.

Sanding work
From Japan

I used it for a year with wearing six hours every day. Although it is good at the beginning, the shape of the silicon surface will collapse and will not close. When checking the back side of the intake valve at the time of filter change, dust is attached a little. The plastic part deteriorates and cracks and cracks. I do not recommend it if you ask for the durability of the mask, the confidence of the filter.

It was easy to work with little invasion of dust, although the price was cheap.

Dust work
From Japan

I was able to use it for a long time ♪ The same thing that I previously purchased at Homsen, the filter cover was quickly deteriorated and replaced by one. Specifically, when filter filter was replaced, filter crack broke. A few years after replacing, the face-to-face (nostrils) became tattered, but it is deterioration due to sebum? Because it is not a thing that I use everyday, I thought whether the maintenance after use was bad I will. Other deterioration is not seen. A few years from the last purchase, please again ♪
