This bulk pack contains eighty replacement 3M Adflo pre-filters designed for use with the 3M Speedglas Adflo respirator system, Speedglas welding helmets, and 3M Versaflo M-Series face shields. These pre-filters play a critical role in maintaining respiratory protection for welders and industrial workers.

The Adflo pre-filter extends the life of the particle filter by capturing larger particles before they reach the main filter. Keeping the pre-filter clean also helps extend the battery run time of the Speedglas Adflo powered respirator. It is important to regularly inspect the pre-filter for any signs of damage, clogging, or breakthrough to ensure optimal respiratory protection.

Pre-filters should not be cleaned but replaced regularly, typically once to twice a week depending on usage intensity. This maintenance schedule helps maintain effective filtration performance and prolongs the lifespan of the respirator system components.
