500 Pairs, One Mount, Zero Roll-Down Hassle: The Moldex 6845 PlugStation Is Built for High-Volume Hearing Programs

When your facility runs 50, 100, or 200 workers past a noise hazard every shift, individual earplug packaging becomes a compliance bottleneck. Workers fumble with wrappers, roll down foam with dirty hands, or skip the step entirely. The Moldex 6845 Pura-Fit PlugStation Dispenser cuts that bottleneck. A single wall-mounted unit delivers 500 pairs of NRR 33 earplugs in a no-roll-down format that workers can grab, twist in, and move on — with no hand contamination and no excuses for skipping PPE.

This review covers everything a safety manager needs to evaluate the 6845: verified specs from the product page, OSHA 29 CFR 1910.95 compliance math, honest shortcomings, competitor comparison, and total cost of ownership. No fabricated claims — every specification is grounded in the WC Safety product listing or applicable regulatory standards.

Moldex 6845 Pura-Fit PlugStation Dispenser NRR 33 500 Pairs Review (2026)

The Moldex 6845 occupies a specific niche: high-throughput, wall-mounted earplug dispensing for occupational hearing conservation programs. It is not a personal carry option and it is not aimed at occasional noise exposure. The 500-pair PlugStation format is engineered for facilities that issue disposable earplugs as part of a documented OSHA-compliant program — think stamping plants, assembly lines, grinding operations, or construction staging areas.

The Pura-Fit earplug inside the dispenser earns its NRR 33 rating under ANSI S3.19-1974, the standard in force when Moldex submitted laboratory data. NRR 33 represents the maximum single-earplug noise attenuation available in a disposable foam format. Under OSHA's 29 CFR 1910.95 hearing conservation mandate, that rating is derated by 50% for real-world performance estimates, yielding an effective protection level of approximately 16.5 dB — sufficient to bring most industrial noise exposures below the 90 dBA action level without dual protection.

The dispenser itself is the story. Wall-mounting means the unit is always at the point of hazard, not locked in a supply cabinet. The no-roll-down tapered design means workers do not need clean, dry hands to achieve a proper fit — they insert with a gentle twist, which matters when operators come straight off a greasy machine. For facilities running a documented OSHA Hearing Conservation Program, that friction reduction translates directly into measured compliance improvement.

Who the Moldex 6845 PlugStation Is For

The 6845 is purpose-built for safety managers running documented hearing conservation programs under OSHA 29 CFR 1910.95. It fits facilities where:

• TWA noise exposures are at or above 85 dBA, requiring a written HCP
• Worker throughput at hazardous areas is high enough that individual packaging creates a bottleneck
• Hand hygiene at point-of-donning is a practical concern (machining, foundry, food processing)
• The workforce includes workers with latex or chemical sensitivities
• Auditors or compliance officers conduct earplug issuance verification

It is not the right choice for workers who need personalized fit options, facilities pursuing zero-waste PPE programs, or environments where noise exposures barely clear the 85 dBA action level and a lower-cost NRR 25–29 plug would be adequate. For a broader comparison of earplug classes, see our guide to reusable vs. disposable earplugs.

Where the Moldex 6845 Performs Well

Maximum-Class Noise Attenuation at NRR 33

NRR 33 is the highest attenuation value achievable in a single-earplug disposable foam device under ANSI S3.19. Under OSHA's mandatory 50% derating method (29 CFR 1910.95 Appendix B), the effective protection estimate is 16.5 dB. Applied to an 8-hour TWA of 100 dBA, that yields a protected exposure of approximately 83.5 dBA — safely below the 90 dBA PEL. For exposure levels up to ~103 dBA TWA, this single device is generally sufficient without dual protection. See our full breakdown in the NRR Hearing Protection Guide.

No-Roll-Down Tapered Insertion

Conventional foam earplugs require rolling the plug into a tight cylinder with clean, dry fingers and then holding it in the ear canal while it expands — a 15–20 second procedure that workers skip or rush under production pressure. The Pura-Fit taper inserts with a single gentle twist, eliminating the roll-down step entirely. This directly addresses the most common disposable earplug compliance gap identified in industrial hygiene audits.

Chemically Inert Material Stack

The Pura-Fit foam is polyurethane-based and certified latex-free, PVC-free, chloroprene-free, and diisocyanate-free. For facilities with workers who have documented latex allergies or isocyanate sensitization — common in automotive, aerospace, and chemical manufacturing — this material profile eliminates earplug substitution workarounds and simplifies HCP documentation.

Wall-Mount PlugStation Deployment

The PlugStation dispenser mounts at the noise hazard boundary, making compliance the path of least resistance. Workers do not need to retrieve earplugs from a cabinet, ask a supervisor, or remember to bring their own. Placement at the point-of-entry is the single most effective compliance intervention identified in hearing conservation literature. The high-visibility yellow-green color of the plugs themselves makes it easy for supervisors and auditors to confirm at-a-glance that workers have inserted protection.

500-Pair Bulk Economics

Each dispenser unit contains 500 pairs — enough to run a 50-person workforce for 10 days of single-shift, or a smaller team for several weeks. Low restocking frequency reduces administrative overhead and supply chain exposure. For purchasing context, see our overview of best foam earplugs for manufacturing.

Where the Moldex 6845 Falls Short

No Dispense Tracking

The PlugStation has no integrated counter or electronic dispense logging. Facilities that need to document per-worker issuance for OSHA audit purposes must implement a separate sign-out sheet or barrier system alongside the dispenser. Some competing dispenser systems offer mechanical pair-count windows; the 6845 does not.

Single Size Only

The Pura-Fit is offered in one size. Workers with very small or irregular ear canals may not achieve an adequate acoustic seal, which undermines the NRR 33 rating in practice. Programs serving anatomically diverse workforces should evaluate whether a second earplug option — such as a corded or banded alternative — is warranted for a subset of workers.

Requires Fixed Wall Surface

The PlugStation format requires a suitable wall surface and mounting hardware. Mobile worksites, temporary hazard areas, or tool crib windows that rotate locations are poor matches for a fixed dispenser. In those contexts, a portable bulk-pack format may be more practical.

Per-Pair Cost Premium

The no-roll-down design and clean material stack carry a per-pair cost premium over standard NRR 29–33 roll-down alternatives. For programs at the 85 dBA action level where an NRR 25 plug would meet the regulatory requirement, the 6845 may represent over-specification. The cost difference is most defensible when insertion compliance is a documented problem or when chemical sensitivity is a workforce factor.

Moldex 6845 vs. Competing Earplug Dispensers

The 6845 leads on both NRR and pairs-per-unit volume, and is the only option in this comparison that combines NRR 33 with a no-roll-down insertion method. For a broader earplug category review, see our Best Earplugs for Work guide.

Compatible Accessories and Program Components

The 6845 PlugStation is designed to slot into a broader hearing conservation infrastructure. Compatible components include:

• PlugStation Mounting Bracket — Wall-mount hardware sold separately; required for installation on smooth or painted surfaces
• Pura-Fit Refill Bags — Bulk refill pairs for restocking dispensers without purchasing additional dispenser housings
• Compliance signage — OSHA-format "Hearing Protection Required" signs rated for the specific dBA zone; pairs with dispenser for complete point-of-hazard stations
• Audiometric testing records — The dispenser supports but does not substitute for annual audiometric testing required under 29 CFR 1910.95(g)

NRR, OSHA 29 CFR 1910.95, and ANSI S3.19: What You Need to Know

The Noise Reduction Rating (NRR) is calculated under ANSI S3.19-1974 laboratory conditions. OSHA requires employers to use the NRR to evaluate hearing protector adequacy under 29 CFR 1910.95. Critically, OSHA mandates a 50% derating of the labeled NRR when estimating real-world attenuation (Appendix B method). For the 6845:

• Labeled NRR: 33 dB
• OSHA-derated effective protection (Method B): NRR × 0.5 = 16.5 dB
• At a TWA of 100 dBA: 100 − 16.5 = 83.5 dBA — below the 90 dBA PEL
• Dual protection generally required above approximately 103 dBA TWA

NIOSH recommends a more aggressive 50–70% derating depending on earplug type. The Pura-Fit's no-roll-down design is explicitly intended to narrow the gap between lab NRR and field performance by reducing improper insertion — but safety managers running programs above 100 dBA TWA should conduct fit testing under 29 CFR 1910.95(f) to verify individual protection. See our OSHA Hearing Conservation Program Guide and NRR Hearing Protection Guide for step-by-step compliance frameworks. Also useful: our roundup of the Best Hearing Protection for Industrial Workers.

Total Cost of Ownership

Evaluating the 6845 purely on unit price understates its program value. Consider the full TCO model:

• Per-pair cost: At $166 for 500 pairs, cost is approximately $0.33 per pair — competitive with individually packaged NRR 29–33 alternatives when administrative overhead is included
• Labor savings: Reduced restocking frequency (500 vs. 200 pairs per unit) cuts supply runs and purchase orders; wall-mount self-service eliminates supervisor issuance time
• Compliance cost avoidance: OSHA hearing conservation violations carry penalties up to $15,625 per willful violation. A documented dispenser program is evidence of good-faith compliance effort
• Audiogram cost offset: Improving actual-use compliance reduces the rate of standard threshold shifts (STS), which trigger additional audiometric follow-up costs under 29 CFR 1910.95(g)(8)
• Workers' comp exposure: Documented noise-induced hearing loss (NIHL) claims average $10,000–$35,000 per case in settled workers' compensation; hearing conservation expenditure is categorically lower

The 6845 is a capital-efficient decision when the alternative is OSHA citation exposure or incremental audiological claims. For broader PPE program cost benchmarking, see the WC Safety PPE collection.

Final Verdict: Is the Moldex 6845 Worth Buying?

Yes — for facilities with documented hearing conservation programs and sufficient worker throughput to justify a wall-mount dispenser. The 6845 PlugStation combines the highest disposable foam NRR available (33 dB, ANSI S3.19 certified) with a no-roll-down insertion design that directly addresses the most common failure mode in earplug compliance programs. The chemically inert material stack removes exclusions for latex-sensitive and isocyanate-sensitized workers. The 500-pair format minimizes administrative overhead.

The limitations are real but narrow: it is not a fit-testing solution, it does not track individual issuance, and it costs more per pair than a basic roll-down alternative at the same NRR. If those limitations matter for your program, evaluate whether a lower-volume format or a corded alternative better fits your workflow. Otherwise, the 6845 is the correct specification for high-throughput industrial hearing programs.

Frequently Asked Questions: Moldex 6845 Pura-Fit PlugStation

What is the NRR of the Moldex 6845?

The Moldex 6845 Pura-Fit PlugStation earplugs carry an NRR (Noise Reduction Rating) of 33 dB, tested under ANSI S3.19-1974. This is the highest NRR available in a single-device disposable foam earplug format.

How does OSHA require employers to apply the NRR 33 rating?

Under 29 CFR 1910.95 Appendix B, OSHA requires a 50% derating of the labeled NRR. For the 6845, this yields an effective protection estimate of 16.5 dB. Applied to a 100 dBA TWA noise environment, the estimated protected exposure is approximately 83.5 dBA — below OSHA's 90 dBA PEL.

What does "no-roll-down" insertion mean?

Standard disposable foam earplugs require the user to compress the plug into a tight cylinder by rolling it between clean fingers, then hold it in the ear canal during expansion. The Pura-Fit design uses a tapered shape that inserts with a gentle twist — no rolling required. This eliminates the need for clean, dry hands at insertion and reduces the time and technique required for proper fit.

Are the Moldex 6845 earplugs latex-free?

Yes. The Pura-Fit foam is certified latex-free, PVC-free, chloroprene-free, and diisocyanate-free. This material profile is suitable for workers with documented latex allergies or isocyanate sensitization.

How many pairs does the 6845 PlugStation dispenser contain?

Each 6845 PlugStation unit contains 500 pairs of Pura-Fit earplugs. At a consumption rate of 50 pairs per day (50-person workforce, one shift), each unit lasts approximately 10 days before requiring a refill.

Does the Moldex 6845 PlugStation require a wall mount?

Yes. The 6845 is a wall-mounted dispenser unit. Mounting hardware is not included and must be sourced separately. The unit requires a stable wall surface; installation on drywall, concrete, or painted cinder block is typical in industrial settings.

Can the Moldex 6845 be used as the sole hearing protection above 100 dBA?

At exposures up to approximately 103 dBA TWA, the 6845 is generally sufficient as a single device under OSHA's 50% derating method. Above 103 dBA TWA, OSHA and NIOSH recommend dual protection — simultaneous use of earplugs and earmuffs. Always conduct a formal noise exposure assessment before determining whether single-device protection is adequate.

Does the PlugStation dispenser track how many pairs have been dispensed?

No. The 6845 does not include an integrated usage counter or dispense tracking mechanism. Facilities requiring documented per-worker earplug issuance records must implement a separate tracking system, such as a sign-out sheet or a dispenser with a mechanical pair counter.

What is the GTIN for the Moldex 6845?

The GTIN for the Moldex 6845 is 0800011305800.

Is the Moldex 6845 compliant with OSHA's Hearing Conservation Amendment?

Yes. The 6845 carries an NRR rating under ANSI S3.19, which is the standard recognized by OSHA for evaluating hearing protector adequacy under 29 CFR 1910.95. It is appropriate for use in a documented hearing conservation program.

What environments is the Moldex 6845 best suited for?

The 6845 is best suited for high-noise industrial environments including stamping plants, metal fabrication, grinding operations, lumber mills, food processing, construction staging areas, and any facility where TWA noise exposure meets or exceeds the 85 dBA OSHA action level and worker throughput at the hazard area is high.

How does the Moldex 6845 compare to 3M E-A-R Classic earplugs in NRR?

The Moldex 6845 Pura-Fit carries NRR 33. The 3M E-A-R Classic carries NRR 29. The 4 dB difference is meaningful at high noise exposures: at 105 dBA TWA, an NRR 29 plug (derated) may not bring exposure below the 90 dBA PEL without dual protection, while NRR 33 provides additional margin. Under OSHA's derating method, every additional NRR point translates to 0.5 dB of effective real-world protection.

Can the Pura-Fit earplugs be reused?

No. The Moldex Pura-Fit earplugs supplied in the 6845 PlugStation are single-use disposable earplugs. They are not designed or labeled for reuse. Reusing disposable foam earplugs degrades the foam structure and risks contaminating the ear canal.

What is the difference between the Moldex 6845 and the Moldex 6800?

Both the 6845 and 6800 use the same Pura-Fit earplug (NRR 33, no-roll-down, latex-free). The 6845 is the 500-pair PlugStation (high-volume wall-mount format); the 6800 is the standard 200-pair dispenser. The 6845 offers lower per-pair economics at scale; the 6800 requires less initial investment.

Where can I buy the Moldex 6845 PlugStation?

The Moldex 6845 is available directly from WC Safety or via Amazon (affiliate link). WC Safety ships PPE to industrial buyers with business account options.

Does fit testing apply to disposable earplugs?

OSHA does not mandate individual fit testing for disposable earplugs under 29 CFR 1910.95; however, NIOSH and the American Industrial Hygiene Association (AIHA) strongly recommend fit testing for workers in environments above 100 dBA TWA. Field attenuation estimation (FAES) systems can verify that the NRR 33 rating is being achieved by individual workers in practice.

What is the color of the Pura-Fit earplugs?

The Moldex Pura-Fit earplugs are yellow-green (high visibility). The high-contrast color is intentional: supervisors and safety auditors can confirm at a glance that workers in the hazard area have inserted their earplugs, supporting visual compliance monitoring.
