The 3M Speedglas with Adflo system is lightweight, compact, and all-in-one. Its exclusive "stackable" configuration means that the cartridge can be "stacked" onto the high efficiency particle filter for additional protection against organic vapours, sulfur dioxide, chlorine, and hydrogen chloride vapors. You can change either the particle filter or the cartridge as needed with the design, no need to change both at the same time. The Adflo system has no external batteries, no battery cables, and no sharp corners. Its slim profile is designed to get into tight spaces.

Available with either just the particulate filter or with both the particulate filter and vapor cartidge. Available filter options include: shade 10, 11, 12, or variable shade 9-13. Lens also available in standard size (3.57" x 1.68") or wide view (4.09" x 2.13").
