Half facepiece air-purifying respirator 3M 6502QLPRO — half-face, blue/grey, quick-connect

The 3M 6502QLPRO half facepiece air-purifying respirator is a reusable respirator designed to protect the wearer from airborne particulates and certain gases or vapours when used with the appropriate filters. The kit includes a medium-sized quick-latch half-face body in blue/grey, combined A2 chemical cartridges and P3 particulate filters, and filter retainers. The respirator is intended for tasks such as spray painting, brush and roller painting, sanding, and work with pesticides and weedkillers.

Advantages

The respirator provides combined A2 protection against some organic gases and vapours (for example solvent-based paints, adhesives and cleaning agents) together with P3 particulate protection offering up to 99% filtration efficiency for fine dust and mists at medium concentrations. A 3M bayonet connection enables secure and straightforward cartridge and filter changes. The quick-latch mechanism allows the mask to be dropped down from the face without removing the head straps, while the silicone face seal is resilient for a comfortable, stable fit. The Cool Flow exhalation valve helps reduce heat and moisture build-up inside the mask.

Suitable for

When it may not be suitable

This half-face respirator is not suitable for atmospheres that are immediately dangerous to life or health (IDLH) or where oxygen levels are below safe limits. It is also not intended for protection against all chemical hazards; suitability depends on selecting the correct A2 and P3 filters for the specific contaminants and their concentrations.

Key specifications

How to use

Select the appropriate A2 and P3 filters for the contaminants and expected concentrations. Fit the respirator to the face and adjust head straps to achieve a snug, comfortable seal; perform a user seal check before each use. Attach cartridges and filters using the 3M bayonet connection until they click into place. During use, the quick-latch mechanism allows the wearer to lower the mask from the face temporarily without removing the head harness. Replace filters and cartridges according to manufacturer guidance and when you detect increased breathing resistance, damage, or contamination.

What to consider before purchase

Recommendations

Use this reusable half-face respirator with the specified A2 chemical cartridges and P3 particulate filters for tasks like painting, sanding and applying pesticides. Always perform a fit check, follow local safety guidance, and replace filters when breathing resistance increases or according to the filter manufacturer’s instructions.
