    The best

    Posted by Marie Holloway on Jul 18th 2019

    Having been past military and having chemical sensitivities, I/we have tried quite a few masks. Great coverage, visibility, fit, ease of use (all off the charts). The seal, most important, is fantastic- we can feel it even without the filters! My touch sensitive family member is even thrilled, which is saying something. Directions are clear and it is easy to keep assembled and clean - if you have to take the few things apart that is easy also.
