Superb mask, can be customized for level of protection.
This is the most comfortable mask yet that I’ve gotten! I don’t have to mess with ear loops adjusters since the neck cord when pulled on automatically tighten the ear loops. Used with a carbon filter they work great for guarding against illnesses or like me in heavy dust and dirt environments. I have four of these mask for myself and don’t need those costly disposable ones. I Just wash the mask with my laundry, then dry and your good to go again. As a Chiropterologist, you constantly need to be aware of your environment and gasses that are involved in this line of work. These mask are great when used with the carbon filters that can be gotten for them. I don’t go anywhere with out one or two on my person. When exploring the entrance to a new cave they work beautifully!  (Note: Do not use in deep caves or caves with heavy Guano deposits due to the Noxious Ammonia Gases given off by bats. A full respirator is recommended for deep bat cave exploration.)<br />But as a general mask for protection against dust, dirt, and general bad stuff they are great! Used with a carbon filter or two filters at a time, these mask will provide you with enough protection for everyday tasks or going out in public. You can never be to safe in this tragic time we are living.
