The 3M™ Secure Click™ HF-800SD Series Half Facepiece Reusable Respirator helps protect against particulates and a wide variety of gases and vapors when used with approved 3M™ Secure Click™ cartridges and filters. Available in three sizes with speaking diaphragm to help provide easier communication while you work.

Breathability: Greater breathability and comfort provided by the world’s first quad flow cartridge system. Two dual flow cartridges on each respirator combine to create four airflow paths for easier breathing.

Simplicity: We’ve replaced the round bayonet connector with the new 3M™ Secure Click™ connection, resulting in a quick, simple cartridge/filter connection. It works just 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. Quick, easy, one-touch user seal check helps provide improved confidence in respirator fit. Speaking diaphragm is designed to help provide easier communication while you work.

Comfort: Designed with smart, intuitive features, this respirator helps provide comfort without compromise. Silicone face seal with patented flex-joint nose bridge helps provide a softer feel for more comfort on the wearer’s face. Easy adjust head cradle buckles – pull straps to tighten, squeeze the buckles to loosen. Exhalation valve helps direct exhaled breath and moisture downward. Advanced silicone material for increased comfort and greater durability.
