Moldex 6870 Meteors Uncorded Earplugs NRR 33 200 Pairs Review (2026)

NRR 33: The Highest-Rated Moldex Disposable — Is the 6870 Worth It on the Floor?

Moldex 6870 Meteors Uncorded Earplugs NRR 33 200 Pairs Review (2026)

When a facility's TWA noise exposure pushes past 95 dBA — punch presses, grinders, impact tools, or heavy machinery — most standard NRR 27–29 earplugs stop providing adequate coverage under OSHA's required 50% derating method. The Moldex 6870 Meteors, with a published NRR of 33 dB and an OSHA-derated effective attenuation of 13 dB, are engineered specifically for those high-exposure environments where the margin between compliance and violation is thin.

The Meteors stand out from the crowded disposable earplug market through a combination of bell-shaped geometry and a wide outer grip flange — a design that addresses one of the most persistent failure modes in hearing conservation programs: incorrect insertion. Gloved workers, operators with dexterity limitations, and anyone working in tight spaces can seat the Meteors correctly on the first attempt far more reliably than traditional cylindrical or bullet-shaped foam plugs. That consistent fit is what converts a rated NRR 33 into real attenuation on the floor, not just on the ANSI S3.19 lab report.

This review covers the Moldex 6870 in the 200-pair dispenser box — the industrial-volume format designed for jobsite refill stations, safety supply cabinets, and high-turnover workforces. We examine the design rationale, real-world fit mechanics, OSHA/ANSI compliance context, total cost of ownership versus competing NRR 33 options, and where the 6870 falls short. No inflated claims — only what the product specification and referenced standards support.

Who the Moldex 6870 Meteors Are For

The 6870 is the right earplug when your hearing conservation program mandates maximum attenuation and you cannot rely on workers to execute a perfect roll-down insertion every time. The bell flange gives a tactile cue — when the wider outer ring is fully seated at the ear canal entrance, the plug is correctly positioned. That feature is specifically valuable in:

• High-noise manufacturing (stamping, pressing, grinding) with TWA exposures above 95 dBA
• Environments where workers are gloved (chemical plants, cold storage, metalworking)
• High-turnover workforces where new employees receive minimal hearing protection training
• Dispenser-station refill programs where 200-pair boxes reduce restocking frequency
• Safety-sensitive industries (mining, heavy construction, utilities) subject to MSHA or OSHA enforcement scrutiny

If your TWA is 85–93 dBA, an NRR 33 earplug is more protection than required — a more economical NRR 27–29 option from the earplug collection may be the better fit. For environments where workers prefer a cord for retrieval, see the corded Moldex 6800 Meteors. For workers with smaller ear canals, Moldex offers the 6820 small-size variant.

Strengths in Detail

NRR 33: Maximum Disposable-Category Attenuation

The Moldex 6870 carries an NRR of 33 dB as measured under ANSI S3.19-1974, the laboratory standard used for all EPA-labeled hearing protectors sold in the United States. Under OSHA's required 50% derating method (the standard used in compliance audits), effective attenuation is calculated as: (NRR − 7) ÷ 2. For the 6870: (33 − 7) ÷ 2 = 13 dB. This places the protected exposure at approximately 103 dBA TWA for a worker in a 116 dBA environment — the practical upper boundary where a single hearing protector remains viable under OSHA 29 CFR 1910.95. Above that threshold, dual protection (earplug plus earmuff) becomes necessary. For the vast majority of heavy industrial environments, NRR 33 provides the compliance margin that protects both workers and employers.

Bell-Flange Design for Consistent Insertion

Traditional cylindrical foam plugs rely entirely on the user rolling the plug into a tight cylinder, inserting it deeply into the canal, and holding it compressed while the foam expands. That three-step technique fails at scale — particularly in training-light environments. The Meteors' bell shape means the wide outer flange naturally aligns at the canal entrance, provides a gripping surface that does not require finger-tip precision, and signals correct depth through tactile contact. The result is a plug that is more forgiving of imperfect insertion technique while still delivering attenuation close to its rated NRR when properly seated. This is not a claim unique to this review — the geometry is the design rationale Moldex documents for the Meteors product family. For a broader comparison of earplug insertion styles, see our guide on best foam earplugs.

Latex-Free and PVC-Free Material

The 6870 is manufactured from polyurethane foam with no latex or PVC content. Latex allergy is a documented occupational health concern in healthcare, food processing, and rubber manufacturing environments. PVC-free composition is increasingly required in food-grade and pharmaceutical facilities where plasticizer migration is regulated. The absence of both compounds also positions the Meteors for workers who experience skin sensitization with conventional earplug materials. This is a material specification, not a medical claim — workers with known latex allergies should confirm with their physician whether polyurethane foam is appropriate for them.

200-Pair Bulk Format for Industrial Programs

Hearing conservation programs under OSHA 29 CFR 1910.95 require employers to make hearing protection available at no cost to employees. The 200-pair box format is designed for refill stations, supervisor-controlled dispensing, and bulk storage — reducing per-unit costs and restocking frequency. At the posted price point, the cost per pair is well below retail single-pair pricing, making the 6870 economically viable for high-consumption facilities. The full hearing protection collection includes dispenser station hardware compatible with the Meteors format.

ANSI S3.19 and OSHA 29 CFR 1910.95 Compliance

EPA-label NRR ratings in the United States are governed by the ANSI S3.19-1974 standard, which specifies the laboratory protocol for measuring attenuation across nine test frequencies. The 6870's NRR 33 is the result of that standardized test — it is not a manufacturer marketing figure. OSHA 29 CFR 1910.95(j) requires that hearing protectors reduce worker TWA exposures to at or below 90 dBA (85 dBA for workers with prior audiometric shifts). The 6870 satisfies that requirement for environments up to approximately 103 dBA TWA when using the 50% derating method. For facilities that prefer NIOSH's recommended 25% derating as a more conservative approach, the 6870 still provides the highest available safety margin in the disposable category. Consult our hearing conservation program guide for full derating method comparison.

Weaknesses and Limitations

Insertion Technique Still Required

The bell-flange design reduces the technique burden compared to cylindrical plugs, but it does not eliminate it. The polyurethane foam still must be compressed, inserted, and held while it expands. Workers who do not hold the plug during the 20–30 second expansion period may experience a partially open fit — reducing effective attenuation significantly below the rated NRR. No earplug — regardless of NRR or geometry — delivers its rated attenuation without correct insertion. Hearing conservation training remains mandatory for hearing protector programs under OSHA 29 CFR 1910.95(k).

Single Regular Size Limits Fit Range

The 6870 is available in a single regular size. Ear canal dimensions vary substantially across a workforce. Workers with smaller ear canals may find the standard Meteors too large to compress and seat correctly, resulting in discomfort or partial fit. Moldex addresses this with the 6820 (small, NRR 28, uncorded) — but a mixed-size program requires managing two SKUs. Facilities purchasing the 6870 should confirm worker fit through a qualified fit-test or trial period before committing to bulk volume. See our best Moldex earplugs guide for sizing comparison across the product line.

Disposable Format Environmental and Cost Considerations

Disposable earplugs are single-use by design — each pair is discarded after one shift or one day of use. For low-noise environments or programs with low headcount, the per-worker annual cost of disposables can exceed that of reusable banded or flanged earplugs. The 6870's 200-pair box mitigates per-pair cost but does not address the waste stream. Facilities with sustainability mandates or waste reduction targets should evaluate reusable versus disposable earplug trade-offs before standardizing on the Meteors format.

No Corded Option in This SKU

The 6870 is uncorded. In some environments — particularly around moving machinery where a dangling cord could become a snag or entanglement hazard — uncorded is the correct and required format. However, facilities where workers remove and replace earplugs frequently during a shift (intermittent noise exposure) often prefer a corded format so plugs are not lost or dropped onto production floors. The corded Moldex 6800 Meteors are the appropriate alternative in those scenarios.

Competitor Comparison

The 6870 and Howard Leight MAX-1 are the two most commonly specified NRR 33 disposable earplugs in U.S. industrial hearing conservation programs. The key differentiator is shape: the MAX-1 uses a contoured taper requiring more precise roll-down technique; the Meteors' bell-flange is more forgiving for gloved or undertrained users. Both are ANSI S3.19 compliant and OSHA-acceptable. The 3M 1100 at NRR 29 costs less per pair but delivers less margin in high-noise environments. See our full best earplugs for work guide for complete rankings.

Compatible Accessories

The Moldex 6870 pairs with several accessory formats for dispenser-based hearing conservation programs:

• Moldex PlugStation Dispensers — wall-mounted or portable dispensers designed for Moldex earplug formats; reduces loose-box clutter in high-traffic areas
• Moldex EcoStation — higher-capacity dispenser format with larger earplug volumes for facilities with large headcount
• Safety supply cabinets — the 200-pair box dimensions are compatible with standard safety cabinet shelf storage

OSHA and ANSI Standards Context

Hearing conservation compliance in U.S. workplaces is governed by OSHA 29 CFR 1910.95 (general industry) and 29 CFR 1926.52 (construction). The standard establishes an Action Level of 85 dBA TWA, requiring hearing conservation program enrollment, audiometric testing, and hearing protector provision. The Permissible Exposure Limit (PEL) is 90 dBA TWA using a 5 dB exchange rate.

Hearing protector adequacy is evaluated by reducing the A-weighted workplace noise level by the derated NRR. OSHA requires the 50% derating method for all NRR-labeled hearing protectors: Derated Attenuation = (NRR − 7) ÷ 2. For the Moldex 6870: (33 − 7) ÷ 2 = 13 dB. A worker exposed to 103 dBA TWA wearing the 6870 would have an effective protected exposure of approximately 90 dBA — the PEL. For workers with Standard Threshold Shift (STS) on audiograms, OSHA requires the protector to reduce exposure to 85 dBA or below. At noise levels above 103 dBA TWA, a second hearing protector (dual protection) would be required for STS-positive workers. The NRR hearing protection guide covers the complete derating calculation methodology. For program-level compliance strategy, see our hearing conservation program guide.

ANSI S3.19-1974 is the measurement standard underlying the NRR label — it specifies the test panel composition, octave-band attenuation measurement protocol, and statistical derivation of the single-number NRR. The NRR represents the mean attenuation minus two standard deviations across all test frequencies, providing a 98th-percentile protection level under ideal laboratory conditions. Real-world attenuation is consistently lower, which is the basis for OSHA's derating requirement. Refer to the AIHA Noise Manual for detailed technical background on hearing protector selection and program management.

Total Cost of Ownership

For a 50-worker facility operating 250 days per year with one pair of earplugs per worker per day, annual consumption is approximately 12,500 pairs. At the 200-pair box price, that represents roughly 63 boxes per year. The per-pair economics of the 6870 bulk format compare favorably to retail single-pair or 50-pair packaging. Factors that affect TCO in earplug programs include:

• Consumption rate — disposable earplugs have high daily turnover; facilities with multi-shift operations multiply daily consumption proportionally
• Loss/waste rate — earplug loss in production environments is common; the 200-pair box format reduces per-pair cost impact of waste
• Training cost — correct insertion training reduces re-do rates and re-issue frequency; the bell-flange design reduces (but does not eliminate) this overhead
• Reusable alternative comparison — for workers in environments with intermittent noise, a banded or flanged reusable earplug may have lower annual cost per worker despite higher unit price; see reusable vs disposable earplugs for a structured comparison
• Audit and compliance cost — failing an OSHA inspection for inadequate hearing protection can result in citations; specifying the highest-NRR disposable available provides the greatest compliance margin

Final Verdict

The Moldex 6870 Meteors Uncorded Earplugs deliver what high-noise industrial programs need: maximum NRR 33 attenuation in a design that accommodates imperfect insertion technique better than cylindrical alternatives. The bell-flange geometry is a genuine functional differentiator — not a marketing feature — that translates to more consistent real-world fit across diverse workforces. The latex-free, PVC-free material composition satisfies regulated-industry material restrictions, and the 200-pair bulk format is purpose-built for dispenser-station programs and high-volume replenishment.

Limitations are real but manageable: single regular size (order 6820 for small-size workers), disposable waste stream, and the inescapable requirement for correct insertion technique regardless of earplug design. If your noise environment demands NRR 33 and your program operates at scale, the 6870 is a well-specified choice with a strong compliance track record.

Frequently Asked Questions

What is the NRR of the Moldex 6870 Meteors?

The Moldex 6870 has an NRR of 33 dB as measured under ANSI S3.19-1974. This is the highest NRR available in the disposable earplug category. Under OSHA's required 50% derating method, effective attenuation is (33 − 7) ÷ 2 = 13 dB.

Are the Moldex 6870 Meteors OSHA compliant?

Yes. The Moldex 6870 is compliant with OSHA 29 CFR 1910.95 hearing conservation requirements. The NRR 33 rating meets OSHA's adequacy requirements for noise environments up to approximately 103 dBA TWA under the 50% derating method.

What is the difference between Moldex 6870 and Moldex 6800?

Both are NRR 33 bell-flange Meteors foam earplugs. The 6870 is uncorded and comes in a 200-pair box; the 6800 is corded and comes in a 100-pair box. Choose the 6800 if workers frequently remove and replace earplugs during a shift and need the cord for retrieval convenience.

Are Moldex 6870 earplugs latex-free?

Yes. The Moldex 6870 is manufactured from polyurethane foam and contains no latex or PVC. This makes them suitable for workers with latex sensitivities and for use in regulated environments that restrict latex materials.

What environments are the Moldex 6870 recommended for?

The 6870 is recommended for high-noise industrial environments with TWA noise exposures above 90 dBA — including stamping, pressing, grinding, machining, and heavy construction — where maximum NRR disposable protection is needed. They are especially useful where workers are gloved or have limited dexterity due to the bell-flange insertion design.

How do I correctly insert the Moldex 6870 Meteors?

Roll the earplug into a thin cylinder using clean, dry fingers. Reach over your head with the opposite hand to pull the ear up and back to open the ear canal. Insert the compressed plug and hold it gently in place for 20–30 seconds while the foam expands to fill the canal. A properly seated plug will feel snug and noticeably reduce ambient sound. Incorrect insertion is the most common cause of below-rated attenuation.

Can the Moldex 6870 be reused?

The 6870 is a disposable earplug intended for single-use or single-shift use. Reuse is not recommended as the foam compresses and loses its elastic recovery over time, reducing both comfort and attenuation. For reusable alternatives, see our reusable vs disposable earplugs guide.

What is the OSHA-derated attenuation of NRR 33 earplugs?

Under OSHA's 50% derating method: (NRR − 7) ÷ 2 = (33 − 7) ÷ 2 = 13 dB effective attenuation. A worker in a 103 dBA environment wearing NRR 33 earplugs has an effective protected exposure of approximately 90 dBA. See our NRR hearing protection guide for full methodology.

Is a size small version of the Moldex Meteors available?

Yes. The Moldex 6820 is the small-size Meteors earplug (uncorded, NRR 28, 200-pair box) for workers with smaller ear canals who cannot achieve a proper fit with the regular 6870. The small size has a lower NRR of 28 dB due to the smaller foam volume. A corded small version is the Moldex 6810.

How many pairs are in the Moldex 6870 box?

The Moldex 6870 box contains 200 pairs. This bulk-format box is designed for refill stations, safety supply cabinets, and high-consumption industrial programs. The pair count makes it one of the most cost-effective per-pair purchasing formats for the Meteors.

How do the Moldex 6870 compare to Howard Leight MAX earplugs?

Both the Moldex 6870 and Howard Leight MAX are rated NRR 33 and are ANSI S3.19 compliant. The primary difference is earplug shape: the Meteors use a bell-flange design that is more forgiving of imperfect insertion technique; the Howard Leight MAX uses a contoured taper that requires a more precise roll-down. Both are valid choices for NRR 33 programs — facility preference and workforce fit should drive selection. See our best earplugs for work guide for side-by-side comparison.

Do I need dual hearing protection with NRR 33 earplugs?

Under OSHA's 50% derating method, NRR 33 earplugs provide 13 dB of effective attenuation. Dual protection (earplug plus earmuff) is required when a single protector cannot reduce exposure to 90 dBA (or 85 dBA for workers with STS). For most environments below ~103 dBA TWA, the 6870 alone is adequate. Above that level, consult your industrial hygienist for a dual-protection protocol. Browse the hearing protection collection for compatible earmuff options.

What is the bell-flange design of the Moldex Meteors?

The Meteors feature a wide outer flange (bell shape) at the external end of the earplug. This flange provides a gripping surface that does not require fine-finger precision to hold during insertion, makes the plug more accessible to gloved workers, and provides a tactile signal of correct seating depth. It is a design feature intended to improve real-world attenuation consistency versus traditional cylindrical foam plugs.

What hearing protection standard does Moldex 6870 meet?

The Moldex 6870 NRR of 33 dB is measured under ANSI S3.19-1974 — the U.S. standard for hearing protector attenuation testing required for EPA NRR labeling. The product is compliant with OSHA 29 CFR 1910.95 for use in employer hearing conservation programs. Our hearing conservation program guide explains the regulatory framework in detail.

Can I use Moldex 6870 earplugs for shooting or hunting?

The Moldex 6870 can provide hearing protection for impulse noise environments like shooting ranges — the NRR 33 rating applies across the tested frequency range. However, earplugs prevent hearing of range commands and environmental sounds, which may be a safety concern in some shooting contexts. Electronic earmuffs are often preferred for shooting because they allow communication while attenuating gunshot peaks. See our best hearing protection guide for shooting-specific recommendations.

Are Moldex earplugs made in the USA?

Moldex-Metric manufactures its foam earplugs in the United States. The company's U.S. manufacturing operations are a documented aspect of its product positioning. Confirm current manufacturing details on Moldex's official product documentation, as sourcing may change.

Where can I buy Moldex 6870 earplugs?

The Moldex 6870 200-pair box is available at WC Safety and from major industrial safety suppliers. For bulk orders and B2B volume pricing, WC Safety's hearing protection collection includes procurement support. Single-pair or smaller quantities are also available through Amazon.

How do I set up a hearing conservation dispenser station with Moldex 6870?

A compliant hearing conservation dispenser station typically includes: a wall-mounted dispenser compatible with the Moldex Meteors format (Moldex PlugStation or EcoStation), adequate supply of 200-pair boxes for your facility's consumption rate, a posted hearing protection policy visible at the dispenser, and training documentation for correct insertion technique. OSHA 29 CFR 1910.95(k) requires that training be provided annually. See our hearing conservation program guide for a full dispenser station setup checklist.
