R3 Safety Moldex Replacement Organic Vapors Filter Cartridge - For 7000 & 9000 Series - NIOSH Approved

R3 Safety Moldex Replacement Organic Vapors Filter Cartridge - For 7000 & 9000 Series

This is the organic vapor cartridge that pairs with Moldex's 7000 and 9000 Series half mask respirators, built around an activated charcoal filtration media that's 100% PVC-free. The charcoal bed adsorbs organic vapor compounds as air passes through it, which is a different filtration job than a particulate filter does -- vapors pass through mechanical particulate media, so this cartridge is specifically for chemical vapor exposure, not dust or aerosol.

It's NIOSH approved for organic vapor protection, and one cartridge type fits both the 7000 and 9000 Series mask bodies, so an operation running both mask models doesn't need to stock two separate cartridge SKUs. Cartridges are sold as a pair, matching how they're installed on the mask.

Key Features & Benefits

• NIOSH-approved organic vapor protection — meets the NIOSH certification standard for organic vapor cartridge respirators, covering a broad range of organic vapors encountered in agricultural and greenhouse settings.
• 100% PVC-free charcoal filtration media — adsorbs organic vapor compounds without relying on PVC in the filter construction, reducing potential off-gassing from the cartridge itself.
• Cross-compatible with 7000 and 9000 Series — a single cartridge type fits both Moldex mask series, simplifying inventory for operations running more than one mask model.
• Drop-in cartridge replacement — swaps onto the mask body quickly between work sessions or as soon as organic vapor breakthrough odor is detected.
• Sold as a pair — matches the two-cartridge configuration used on the mask body, so one order covers one full respirator's worth of filtration.

Who Should Use This

These cartridges are for growers, greenhouse workers, and agricultural professionals already using Moldex 7000 or 9000 Series half mask respirators in environments with organic vapor exposure, such as pesticide mixing, spraying, or other chemical handling tasks where vapor-specific filtration is required.

About R3 Safety

R3 Safety is a wholesale redistributor. It carries more than 30,000 SKUs across safety brands. Those SKUs serve distributor partners nationwide. R3 Safety is now part of ORS Nasco. ORS Nasco is a large industrial MRO wholesaler. That acquisition closed in 2025. R3 Safety does not manufacture this respirator or cartridge. Both are made by Moldex instead. Moldex is a long-established maker of respiratory protection equipment. R3 Safety distributes it through its broader PPE catalog.

Frequently Asked Questions

Are these cartridges NIOSH approved?

Yes, these Moldex organic vapor cartridges are NIOSH approved, meeting the certification standard for organic vapor respirator cartridges. Confirm the NIOSH approval label on the cartridge packaging matches the hazard you're protecting against before relying on it.

How often should organic vapor cartridges be replaced?

Replace cartridges per NIOSH guidance and manufacturer service-life recommendations, and immediately if you detect breakthrough odor, taste, or irritation while wearing the mask. Waiting for a noticeable smell is not a substitute for following a documented change-out schedule where one is required for your workplace.

Do these cartridges work on both the 7000 and 9000 Series masks?

Yes, this cartridge is designed to be cross-compatible with both the Moldex 7000 and 9000 Series half mask respirator bodies. That means an operation running both mask models can standardize on a single organic vapor cartridge rather than stocking separate SKUs.

Why is PVC-free construction relevant for a filter cartridge?

PVC-free construction avoids the potential off-gassing that PVC-containing components can introduce into the airstream the wearer is breathing through the cartridge. For a product whose entire job is protecting air quality at the face, minimizing any material contribution from the cartridge itself is a reasonable design priority.
