The 3M™ Adflo™ Prefilter 15-0099-99X12 is designed to extend the service life of the primary High-Efficiency (HE) filter in the 3M™ Adflo™ Powered Air Purifying Respirator (PAPR). Installed inside the turbo filter cover between the spark arrestor and the HE particulate filter, this lightweight disposable prefilter captures larger airborne particulates before they reach the main filter. Ideal for welding applications and other particulate-generating environments, the Adflo™ prefilter helps maintain optimal airflow while supporting the overall performance of the Adflo™ respiratory protection system.

Key Features
