3M 8212 N95 Welding Particulate Respirator
Sold in bags of 10.
This mask compares to the now discontinued 3M 9920. A more direct cross would be the 3M 8512, but that mask does not have the full sealing flange that the 8212 has. We like this mask better for that reason, since we are using this respirator against fairly toxic challenges.

Hi, I would like to know how many times we can use each mask.1 answer
There is no set life, or number of uses, for the 3M 8212 Welding Mask. Mask (filter) life varies widely, depending on the concentration of welding fumes or other particulates. In the case of a fume filter, the amount of fumes (and dust) in the air will have a huge impact on filter life. Lots of fumes or a very dusty environment equals short(er) life, less fumes equals longer.
When breathing through the mask, it should be fairly easy to inhale. As the filter material becomes loaded, inhaling becomes progressively harder. The filter is actually becoming more efficient, but there is a point at which the increased effort makes this problematic, and you need to change the mask.
Also, with welding masks we want to watch out for physical damage to the mask. For instance, welding sparks can melt a hole in the mask. Long way of saying it depends on how the product is used, and your mileage may vary… There is no hard and fast time limit.
