Collection: Masks Accessories

How to choose compatible CBRN components

Accessories must be chosen as parts of a complete respiratory-protection system. First identify the component you already have and the part you need: a powered blower, hose, full-head hood, mask, or filter.

The products in this collection use compatible 40mm threaded connections, but a matching thread does not guarantee that every combination is complete or appropriate. Confirm the required airflow path, hose, filter, power source, and wearer interface on each product page.

Standalone components are not automatically ready-to-use protective systems. If you need a complete powered configuration, compare the products in our CBRN PAPR systems collection. For filter connection details, read the 40mm compatibility guide.
