Moldex 7740 Semi-Rectangular P100 Particulate Filter for 7000/7800/9000 Series Respirators

The Moldex 7740 is a semi-rectangular P100 particulate filter designed for use with Moldex 7000, 7800, and 9000 series reusable half-mask and full-face respirators. NIOSH approved with a filtration efficiency of 99.97% or greater, this filter provides maximum particulate protection against both oil-based and non-oil-based aerosols, making it suitable for demanding industrial and safety applications.

The 7740 features Moldex's innovative semi-rectangular shape, which increases the filter's surface area compared to traditional round filter disks. This expanded surface area reduces breathing resistance for improved comfort and extends the usable service life of each filter — lowering the overall cost of ownership.

Key Features:

• NIOSH Approved P100 — 99.97% or greater filtration efficiency against oil and non-oil based particulate aerosols
• Semi-rectangular design — larger surface area than traditional filter cartridges for easier breathing and longer service life
• Dura-Mesh® encased — protective outer shell provides durability for rough handling environments
• Lightweight construction — lighter than traditional filter cartridges for all-day wear comfort
• Keyless bayonet-style attachment — quick and easy tool-free assembly
• Meets heat and flame resistance per ANSI/ISEA 110-2009 Section 7.11.1
• Compatible with Moldex 7000, 7800, and 9000 series facepieces
• 100% PVC-free construction
• Made in the USA — filter production takes place entirely in Moldex's California facilities

P100 Recommended Applications: Asbestos, lead, inorganic arsenic, cadmium, MDA, and other contaminants requiring a HEPA-level filter per OSHA substance-specific standards. Also suitable for pharmaceutical, battery, nuclear, welding, and metal processing environments where oil-based particulates may be present.

Sold as a pair. Can be piggybacked with any Moldex semi-rectangular gas/vapor cartridge using the 7927 Piggyback Adapter for combination protection against both particulates and chemical vapors.
