Moldex 7760 P100 Filter Nuisance Organic Vapor Acid Gas

Moldex 7760 Overview

The Moldex 7760 is a P100 particulate filter with nuisance-level organic vapor and acid gas sorbent that mounts on Moldex 7000, 7800, and 9000 series respirators. Sold as a single filter at $5.31, it delivers NIOSH-rated P100 particulate efficiency (≥99.97%, including oil-based aerosols) while the integrated activated carbon layer reduces ambient solvent and acid-gas odors to a more tolerable level — without meeting the NIOSH standard for a rated chemical cartridge. This is the same functional concept as the 3M 2097: the P100 disc does the compliance work; the carbon layer does comfort work only.

Best Applications for the Moldex 7760

Auto Body Repair and Primer Application

Auto body technicians applying body filler, primer, and paint in ventilated spray environments represent the core use case for the 7760. The airborne mist from spray guns — polyurethane, epoxy, isocyanate-free primers — constitutes the primary regulated hazard, and P100 is the appropriate filter class. Solvent vapors in a properly ventilated booth may remain below OEL, making the nuisance OV relief a comfort benefit rather than a compliance gap. Workers in this trade will find the Moldex half-mask respirator paired with 7760 filters to be a cost-effective daily setup. Note: if isocyanate-containing products are in use, confirm your IH assessment before relying on nuisance OV relief alone.

Paint Spray Operations (Non-Isocyanate)

General paint spray work — latex, alkyd, and enamel systems — generates respirable mist as the primary hazard. Solvent carriers at ventilated booth concentrations typically fall into nuisance territory. The 7760 is a practical one-filter-does-both solution: P100 for the mist, carbon sorbent for the paint smell. At $5.31 per filter, daily or per-shift replacement remains affordable. For spray painters working in enclosed or poorly ventilated areas where solvent concentrations may be higher, the rated Moldex 7367 OV/AG + P100 combination cartridge is the safer selection.

Grinding, Sanding, and Cutting Metal or Composites

Metal grinding, fiberglass cutting, and composite sanding create fine respirable particulate that demands P100 filtration. Coolant residue and adhesive fumes on worked surfaces can release minor OV/AG odors as the abrasive heats the material. The 7760 handles both without requiring the worker to switch to a heavier combination cartridge. This application is low chemical-vapor risk, making nuisance relief adequate. Browse the full Moldex cartridge and filter collection for complete options.

Woodworking with Lacquers and Shellac

Fine woodworking shops that apply lacquers, shellacs, or solvent-based stains in well-ventilated spaces often generate particulate (sanding dust) alongside solvent odors. Where engineering controls keep solvent concentrations below OEL, the 7760 provides P100 dust protection plus odor comfort in a single compact filter. Shops with poor ventilation or high-production spray volume should move to a rated cartridge with P100 media.

Maintenance and Facility Operations Near Chemical Storage

Maintenance technicians working on equipment or performing dusty tasks in areas where chemicals are stored may encounter incidental OV or mild acid-gas odors from nearby activity. The 7760 addresses the particulate compliance requirement while providing background odor relief. If the maintenance task itself involves direct chemical handling, consult your respiratory protection program for the correct cartridge rating.

Moldex 7760 Pros and Cons

Compatible Moldex Respirators

The 7760 uses the standard Moldex bayonet-mount connection, making it compatible with every Moldex reusable half-mask and full-face platform. It does NOT fit any non-Moldex respirator — bayonet dimensions, thread pitch, and sealing geometry are proprietary to Moldex and do not interchange with 3M, Honeywell North, MSA, or any other brand.

Moldex 7760 Quick Answers

Does the Moldex 7760 provide rated organic vapor protection?

No. The Moldex 7760 provides nuisance-level organic vapor odor relief only. Its activated carbon layer reduces OV odor intensity at concentrations below occupational exposure limits but does not meet the NIOSH standard for a rated OV chemical cartridge. Where OSHA requires a rated OV cartridge, use the Moldex 7100 or the Moldex 7367 combination cartridge.

Is the Moldex 7760 the same concept as the 3M 2097?

Yes — functionally. Both the Moldex 7760 and the 3M 2097 combine a NIOSH P100 particulate filter with nuisance-level OV relief from an activated carbon layer. Neither is a rated OV chemical cartridge. The key difference is platform compatibility: the 7760 fits only Moldex respirators; the 3M 2097 fits only 3M 6000/7000 series facepieces.

How often should the Moldex 7760 be replaced?

Replace the 7760 when breathing resistance increases noticeably (particulate loading indicator), when the filter is physically damaged, or at the end of your shift if odors become detectable through the filter at the end of use. Because the 7760 carries no ESLI, follow an OSHA-compliant change-out schedule established by your employer's industrial hygienist based on the specific chemicals, concentrations, and use time in your work environment.

Can I use one Moldex 7760 on a full-face respirator?

Full-face Moldex 9000 series respirators have two filter/cartridge ports — one on each side of the facepiece. A complete working setup requires two 7760 filters (one per side). Since the 7760 is sold individually, purchase two units when outfitting a full-face facepiece.

What is the difference between nuisance-level relief and rated chemical cartridge protection?

A rated chemical cartridge is NIOSH-approved with measured breakthrough data, a defined service life formula, and OSHA-accepted capacity for specific gases at defined concentrations. Nuisance-level relief means the sorbent reduces odor perception below the detection threshold at concentrations already below the OEL — it carries no breakthrough rating and no NIOSH chemical cartridge approval. Our guide Nuisance Relief vs Rated Respirator Protection covers this in detail.

Does the Moldex 7760 fit Moldex 8000 series disposable respirators?

No. The 8000 series are disposable N95-class filtering facepiece respirators — there are no cartridge ports. The 7760 bayonet filter is compatible only with the reusable 7000, 7800, and 9000 series facepieces.

Is the Moldex 7760 good for spray painting?

Yes, for conventional spray painting with non-isocyanate coatings in a properly ventilated booth where solvent concentrations are confirmed to be at nuisance levels only. The P100 filter handles paint mist — including oil-based aerosols — and the carbon sorbent reduces background solvent odor. If the paint system contains isocyanates or if air monitoring has not confirmed sub-OEL solvent levels, step up to the Moldex 7367 with rated OV/AG + P100 protection.

Moldex 7760 Frequently Asked Questions

Will the Moldex 7760 protect me from chemical vapors at work?

Only at nuisance concentrations — not at OSHA compliance levels. The 7760 uses activated carbon to reduce OV and AG odors when those vapors are present below their occupational exposure limits. If your employer's air monitoring data shows OV or AG concentrations at or above the action level or PEL, a rated chemical cartridge is required. The 7760's carbon layer is a comfort feature, not a compliance solution for chemical vapors.

Can I buy just one Moldex 7760 instead of a pair?

Yes — the 7760 is specifically sold as a single filter at $5.31 per unit. This is one of its key selling points compared to pair-packed filters like the 7740. You can replace filters one at a time, which is practical for situations where one filter wears out before the other or when outfitting a half-mask that sees uneven wear.

Does the Moldex 7760 work for lead dust or silica exposure?

Yes — P100 particulate filtration at ≥99.97% efficiency is appropriate for lead dust and respirable crystalline silica, both of which OSHA regulations frequently require P100-class protection for. The 7760 meets that particulate requirement. The OV/AG nuisance layer is simply an added comfort feature that does not affect the P100 particulate performance.

How do I know when to replace the Moldex 7760?

Replace immediately if the filter is damaged, visibly soiled, or breathing resistance increases enough to affect normal use. For the OV/AG sorbent layer, replace before breakthrough — when you begin smelling vapors through the filter during use. Because the 7760 carries no ESLI, your employer must establish a written change-out schedule based on OSHA 1910.134 requirements, including concentration data and use-time tracking from your industrial hygienist.

Is the Moldex 7760 suitable for welding fume?

Yes, for the particulate component of welding fume — fine metal oxides and fumes — P100 filtration provides the highest level of particulate protection available in an air-purifying respirator. If welding produces coatings-related vapors (burning galvanized metal, painted metal, flux fumes), the nuisance OV relief may reduce odor. For welding in chromate, manganese-heavy, or chemical-contaminated material environments, confirm with your IH whether rated chemical protection is also required.

What is the price difference between the Moldex 7760 and the 7367 combination cartridge?

The 7760 is $5.31 per single filter; you need two for a half-mask (total $10.62) or two for a full-face (total $10.62). The Moldex 7367 OV/AG + P100 combo cartridge is $11.62 per set (typically a pair). The 7367 costs roughly $1 more per set but provides rated OV and AG chemical cartridge protection in addition to P100 particulate — a meaningful compliance step up for a minimal price difference.

Can I use the Moldex 7760 on a full-face respirator for spray painting?

Yes, the 7760 is compatible with the Moldex 9000 series full-face respirator. Install one 7760 on each side port for complete P100 protection with nuisance OV/AG odor relief. For full-face spray painting where solvent concentrations may be elevated — especially in enclosed booths — confirm that nuisance-level OV relief is sufficient for your specific paint chemistry before relying on the 7760 as your sole chemical protection.

Does the Moldex 7760 fit the Moldex 7002 half-mask?

Yes. The Moldex 7002 is part of the 7000 series half-mask line, and all 7000 series facepieces (7001, 7002, 7003 — small, medium, large) accept the 7760 bayonet filter. The filter connection is identical across all three sizes.

Is there a Moldex filter that provides rated OV protection AND P100 particulate?

Yes — the Moldex 7367 OV/AG + P100 combination cartridge ($11.62/set) provides NIOSH-rated organic vapor and acid gas cartridge protection combined with P100 particulate filtration in a single unit. If you need rated multi-gas protection with P100 and an ESLI, the Moldex 7667 Multi-Gas + P100 Smart cartridge ($18.50/set) adds an end-of-service-life indicator.

Does the Moldex 7760 have an expiration date?

Sealed, unopened filters typically have a manufacturer-stated shelf life (commonly 3–5 years from production date) when stored in original packaging away from heat, humidity, and chemical contamination. Once opened and in use, service life is determined by particulate loading and the OV/AG breakthrough schedule established by your respiratory protection program — not a calendar date. Check the packaging or contact Moldex directly for the specific shelf life printed on your batch.

What respirator series should I buy to use with the Moldex 7760?

The two primary platforms are the Moldex 7000 series half-mask ($24.19) for standard industrial use and the Moldex 9000 series full-face respirator ($226.90) when eye and face protection is also required. Both accept the 7760 bayonet filter. Browse the full Moldex half-mask respirator collection and Moldex full-face respirator collection to select the correct facepiece size.

Is the Moldex 7760 available in multi-pack quantities?

The 7760 is sold individually (1 per bag) on wcsafety.com at $5.31 per unit. For high-volume needs, order the required quantity directly. Because it is priced per single filter rather than per pair, it is easy to match your exact replacement cycle without purchasing excess inventory.
