Respirator - Secure Click™ Half Facepiece Reusable with Speaking Diaphragm HF-802SD Large 10/CS

The 3M™ Secure Click™ Half Facepiece Reusable Respirator with Speaking Diaphragm utilizes the 3M™ Secure Click™ Connection, replacing the commonly-used round bayonet connector. This results in a quick, simple cartridge/filter connection that functions like a seat belt. Simply align the connections and push until you hear a 'click' and feel confident that filters and cartridges are installed properly. For improved peace-of-mind, simply use the easy, one-touch user seal check to help ensure a proper fit.
