The 3M Project Safety Kit is recommended for a woodworking or fiberglass insulation project, and includes an N95 3M Sanding/Fiberglass Respirator, 3M Chemical Splash/Impact Goggles and 3M Corded Reusable Earplugs. So, whether you use all three components at once, or each one individually, you can rely on the trusted protection of the 3M Project Safety Kit.
