3M™ 1744 / 1744C Particulate Filter

The 3M™ 1744 and 1744C are economical particulate filter pads for 3M half- and full-face respirators. The 1744C version adds an activated-carbon layer that reduces nuisance organic-vapour and ozone odours alongside particulate filtration.

Product overview

These filter pads fit 3M respirators that use the 5000-series retainer system (such as the 501 retainer). The 1744 captures fine dusts and mists, while the 1744C adds a carbon layer for nuisance odour relief, making the pair versatile for many light-to-medium dust tasks.

Key features and benefits

• Particulate filtration: captures fine dusts and mists (P2 class).
• 1744C carbon layer: reduces nuisance organic-vapour and ozone odours below the exposure limit.
• Economical: low-cost pads that are easy to replace.

Typical applications

The 1744 / 1744C suit sanding, sweeping, light grinding, woodworking and general dusty tasks; the 1744C is preferred where mild solvent or ozone odours are also present.
