3M innovation makes their NIOSH-approved Secure Click respirator as safe as it is simple to use. The half-face HF-800 features a speaking diaphragm, to allow speech without removing the mask.

You'll also breathe easier, literally, with 3M's first-of-its-kind quad-flow cartridges. Innovation in this respirator ensures your workplace safety isn't another chore.
