Half Facepiece Respirator

The 3M Half Mask Respirator is a reusable half facepiece designed for respiratory protection in industrial settings. It uses a bayonet connection system compatible with approved 3M cartridges and filters. The mask is constructed from a silicone and nylon blend and is sold individually in size Medium.

Facility Maintenance and Grinding

This respirator suits workers in facility maintenance, grinding, machine operations, sanding, welding, demolition, and assembly cleaning. It is not intended for environments requiring a full facepiece or supplied-air systems. Buyers needing protection against gases or vapours not covered by approved 3M cartridges should look at alternative solutions.

Bayonet Connection Type

The bayonet connection determines which cartridges and filters attach to the facepiece. Only 3M-approved components with the matching bayonet fitting will seal correctly. Verify that your required filter or cartridge uses this connection before purchase.

Questions about this item

Which 3M cartridges or filters must I already own to use this bayonet half-mask?

The mask accepts 3M-approved bayonet cartridges and filters; choose the combination rated for your specific airborne contaminants.

Will this size M half-mask seal over my existing safety glasses or welding helmet?

The low-profile half-face design and adjustable head straps leave room for most eye and head protection while maintaining a secure seal.

How do I confirm the Quick Latch and bayonet connections are seated correctly before entering a dirty environment?

Engage the Quick Latch until it clicks, twist each cartridge until the bayonet locks, then perform a positive and negative pressure seal check.
