3M Secure Click Half Mask Respirator

3M Secure Click Half Mask Respirator HF-800 features a speaking diaphragm, to allow speech without removing the mask. The innovative "Secure Click" namesake applies to the easy swap filters, yet could also apply to the one-touch seal check, giving you confidence that your mask and filters are properly in place. You'll also breathe easier, literally, with 3M's first-of-its-kind quad-flow cartridges.
