3M 6502QL Quick Latch Half Facepiece Respirator (Medium)

The 3M 6502QL respirator (code 49490) is a reusable half-face mask with 3M’s Quick Latch drop-down mechanism in a medium size. A simple one-handed pull lets the wearer drop the mask to talk or take a break without removing it completely, so it is ideal for jobs with frequent breaks.

Product overview

The 6502QL is part of 3M’s 6500QL Series of reusable half-face respirators. Because it adds the Quick Latch feature to the comfortable 6500 facepiece, the mask can be lowered and re-sealed quickly, which improves productivity on stop-start tasks. It uses the 3M bayonet connection, so it works with the full 3M cartridge and filter range.
