Reusable Respirator Mask with Filters - Half Face Welding Respirator Paint Mask, Dust Mask Respirator for Woodworking Mold Painting Sanding Cleaning

Excellent Dust Mask. My brother used this mask for sanding down dry line filler, I've bought a few 3m similar masks to this with filters on them in the past and they have let quite a bit of dust through, this mask fits perfect and didn't let any dust through at all. Well worth the money and my brother's lungs appreciated it too.
