Dentec Safety supplies a complete range of cartridges so you can choose the appropriate protection for your application.

Our "Saf-Twist" design quickly attaches to any Dentec Safety half-mask of full-face air-purifying respirator facepiece. The offset connector design improves visibility and allows face shields or welding helmets to be worn without interference.

Interchangeable cartridge/filter configurations allow you to re-configure your protection easily and inexpensively for use in different applications, simplifying inventories.

Cartridges are uniquely designed with a space plenum between the filtering material and the inhalation port. Inhaled air is evenly distributed across the filter which lowers breathing resistance and extends cartridge life.
