Good for welding, not suitable for virus situation
Short version: As described. Fit my welding mask. Mask sends out spitdrops: Very bad for virus.
Long version:
This product arrived on time and was as described. Great. I've been using them for years in my welding half mask respirator while at my metal fabrication job. Caution though: I'm writing this review in the time of the covid 19 outbreak and I highly *discourage* the use of it for stopping the spread of the disease or protecting yourself or loved ones. Bad idea. If you are sick or there is any remote chance that you have come in contact with the virus from a person or a surface, which is statistically high, and happen to become even an asymptomatic carrier, you may infect others: Spit drops fly or drip out the middle of the half mask respirator (the valve) that matches with these filters as one breathes out. This is normal with the respirator and simply part of how it works. But please don't endanger this world or people around you trying to use this for the virus - - It's counterproductive in virus mitigation. And also please reserve these masks for the use of welders, painters, woodworkers, and other people who deal with particles or fumes at work. We need to protect ourselves from hazards at our jobs. The half mask and these filters that match with it work great for these occupations and fit very well under a welding hood.
