Moldex 6845 Pura-Fit PlugStation Review: 500-Pair Earplug Dispenser (NRR 33)
WC Safety Editorial Verdict: 4.5/5
The Moldex 6845 Pura-Fit PlugStation earns our recommendation as the high-volume dispensing choice for facilities that want comfort-driven NRR 33 foam compliance without frequent refills: 500 pairs of latex-free smooth-skin Pura-Fit cut a 100-worker station's refill cadence roughly in half versus the 250-pair 6844. The smooth skin is the differentiator — it reduces the mid-shift friction that drives discard rates with commodity foam, which is the practical reason high-traffic primary stations sustain wear compliance better with this dispenser than with a bulk box. Editorially we score it on its merits as a dispensing system; no verified customer rating is available for this listing yet, so treat the score as our hands-on assessment of fit, comfort, and operational value rather than aggregated buyer feedback. Compare it against the corded moldex 6900 pura fit corded or step up to the full nrr 33 ear plugs range before committing a multi-station rollout.
Moldex 6845 Pura-Fit PlugStation Review: 500-Pair High-Volume Dispensing for Facilities That Prioritize Both Scale and Comfort
The case for high-volume earplug dispensing at primary production-line entry points is straightforward: the longer it takes to refill a dispenser, the less supervisory time is spent on that task, and the less likely a dispenser is to run empty during a peak shift. The Moldex 6845 Check Price on Amazon → Pura-Fit PlugStation delivers 500 pairs of smooth-skin, latex-free Pura-Fit foam earplugs at NRR 33 in a wall-mount individual-dispensing format — double the capacity of the Moldex 6844 PlugStation — for facilities where comfort-focused earplug compliance at scale is the operational priority.
OSHA 29 CFR 1910.95: At 85 dB TWA, hearing conservation programs must be in effect and hearing protectors made available. At 90 dB TWA, hearing protection must be worn. High-volume dispensing capacity supports continuous availability, which OSHA expects at all times during noise-hazard operations.
Why 500-Pair vs. 250-Pair Matters at Scale
The difference between a 250-pair and a 500-pair PlugStation is not just storage capacity — it is operational rhythm. Consider a primary production line with 60 workers across three shifts, each drawing one pair at shift start:
| Scenario | Pairs/day | 6844 (250-pair) interval | 6845 (500-pair) interval |
|---|---|---|---|
| 60 workers, 3 shifts | 60 | ~4 days | ~8 days |
| 100 workers, 3 shifts | 100 | ~2.5 days | ~5 days |
| 40 workers + contractors | 55 | ~4.5 days | ~9 days |
At a 100-worker facility, the 6844 requires refilling roughly twice per week. The 6845 reduces that to once per week — a 50% reduction in refill events at the same station. Across a multi-station facility with five to ten dispensers, this weekly time savings is meaningful for the safety coordinator or team responsible for maintenance rounds.
Pura-Fit Smooth-Skin at NRR 33: Why Comfort Drives Volume Compliance
The most common cause of earplug under-usage in high-volume programs is not access — it is comfort. Workers at primary production lines who spend 8–10 hours per shift in continuous noise exposure report significantly higher earplug discard rates with rough-surface foam earplugs than with smooth-skin formats. The discard pattern is predictable: workers insert correctly at shift start, experience growing discomfort by midshift from the foam surface friction, remove the earplug for relief, and fail to re-insert.
Pura-Fit's smooth skin reduces this friction mechanism without sacrificing NRR. At NRR 33, Pura-Fit provides the same attenuation as the rougher-surface industry-standard foam earplugs, but with a comfort profile that supports sustained 8-hour wear. This is the core argument for the 6845 over a generic 500-pair bulk dispenser of commodity foam plugs.
For workers who still find standard foam pressure uncomfortable after switching to Pura-Fit, the ultra-low-pressure Mellows earplug (available in the Moldex 6847 500-pair Mellows PlugStation) offers a further step down in expansion force, at NRR 30.

Cost-Per-Pair Analysis: PlugStation vs. EcoStation at 500-Pair Scale
At high-volume facilities, cost per pair is a real purchasing decision. The 500-pair PlugStation format sits between the lowest-cost bulk box (no dispenser, open access) and the EcoStation format (hopper dispenser, bulk bag refill).
| Format | Relative Cost/Pair | Hygiene | Per-Plug Accountability | Refill Labor |
|---|---|---|---|---|
| 6845 PlugStation (500-pair) | Higher | High | High | Low (infrequent) |
| EcoStation 6706 (Pura-Fit bulk) | Medium | Medium | Low | Very low |
| Bulk box (commodity foam) | Lowest | Low | None | High (frequent replacement) |
The 6845 PlugStation premium over EcoStation format is justified when: (a) individual dispensing hygiene is a compliance or customer requirement, (b) per-plug accountability supports your hearing conservation program documentation, or (c) the reduced refill frequency of 500-pair capacity offsets the per-pair cost premium in labor savings.
For bulk Pura-Fit dispensing at even higher volume, see the Moldex 6706 Pura-Fit EcoStation refill.
NRR 33 and OSHA Compliance
| Environment | Noise Level | Effective Exposure (NRR÷2) | Status |
|---|---|---|---|
| Automotive assembly | 92 dB | 75.5 dB | Compliant |
| Metal fabrication | 97 dB | 80.5 dB | Compliant |
| Stamping press | 102 dB | 85.5 dB | Within limits |
| Chipping/blasting | 108 dB | 91.5 dB | Double protection |
See the NIOSH guide for full derating methodology. For environments above 105 dB, combine Pura-Fit earplugs with earmuffs from the hearing protection collection.
How to Refill the Moldex 6845 PlugStation
- Press both front-panel release tabs simultaneously and open the dispenser door.
- Remove any remaining Pura-Fit pairs from the magazine channel.
- Load Pura-Fit uncorded refill pairs into the channel. At 500-pair capacity, refill events are infrequent — use this opportunity to inspect the dispensing mechanism and channel for debris.
- Close the panel until both tabs click.
- Test-dispense one pair to confirm operation.
- Log the refill event with date and pair count in your hearing conservation records.
Frequently Asked Questions
What is the NRR of the Pura-Fit earplugs in the 6845 PlugStation?
NRR 33. NIOSH NRR÷2 derating gives approximately 16.5 dB of real-world attenuation for continuous noise exposures.
How does the 6845 differ from the 6844 PlugStation?
Both dispense Pura-Fit smooth-skin foam earplugs at NRR 33. The 6845 holds 500 pairs; the 6844 holds 250. Choose 6845 for high-volume primary stations. Choose 6844 for secondary stations and lower-traffic locations.
Does smooth-skin foam reduce the acoustic seal compared to rough foam?
No. The acoustic seal is provided by the compressed foam core expanding against the ear canal. The smooth skin is an outer surface treatment only — it does not reduce foam density, expansion, or the resulting NRR 33 acoustic performance.
Are Pura-Fit earplugs latex-free?
Yes. Pura-Fit earplugs are latex-free. Suitable for workers with latex allergies or sensitivities.
How long will a 6845 PlugStation last at a high-volume production entry point?
At 100 pairs per day (100 workers per shift start), the 6845 lasts approximately five days. At 60 pairs per day, approximately eight days. Establish a refill schedule based on your actual daily draw rate tracked over the first two weeks of deployment.
Is the 6845 appropriate for food processing facilities?
Yes. Individual dispensing is hygienically superior to open bulk dispensers in food processing environments. The lime green color is also visible in product streams for foreign material detection purposes.
What OSHA documentation supports the 6845 deployment?
OSHA 29 CFR 1910.95(c) requires engineering and administrative controls be used when feasible, with PPE as supplemental. Your hearing conservation program should document dispenser placement locations, refill logs, and employee training records. The 6845's individual dispensing format supports per-location accountability documentation.
Can I deploy 6844 and 6845 dispensers in the same facility for different station types?
Yes. Many facilities use 500-pair dispensers at high-traffic primary entry points and 250-pair dispensers at secondary stations, guardhouses, and visitor entry. Both dispense the same Pura-Fit earplug, so worker familiarity with insertion technique carries across locations.
Are Pura-Fit earplugs NIOSH-listed?
Yes. Moldex Pura-Fit earplugs are NIOSH-listed with NRR 33 under 42 CFR Part 84.
Does the 6845 include a wall-mount bracket?
Yes. The wall-mount bracket is included. Two anchor screws are required for installation (not included). No tools are needed for the dispenser mechanism itself.
Can workers with ear canal sensitivity use Pura-Fit earplugs?
Pura-Fit's smooth skin significantly reduces the friction and micro-abrasion that causes discomfort in workers with ear canal sensitivity. For workers whose sensitivity is related to pressure rather than friction, the ultra-low-pressure Moldex 6847 Mellows PlugStation may be a better fit.
What is the refill pair for the 6845 PlugStation?
Moldex Pura-Fit uncorded refill pairs. Do not use other Moldex foam earplug models — the PlugStation channel is model-specific.
How does the 6845 compare to the EcoStation 6706 for Pura-Fit?
The 6845 PlugStation offers individual pair dispensing (better hygiene, higher per-pair cost). The 6706 EcoStation uses a bulk-bag hopper (lower cost per pair, less individual hygiene, higher volume per refill bag). High-volume facilities often use EcoStation at primary lines and PlugStation at secondary stations.
Is the 6845 appropriate for pharmaceutical GMP environments?
The individual dispensing format reduces cross-contamination risk compared to open bulk dispensers. Consult your facility's contamination control SOP. The lime green color supports foreign-material detection requirements.
Where can I buy the Moldex 6845 Pura-Fit PlugStation?
Check availability on Amazon Check Price on Amazon → or browse the WC Safety earplug collection. See all hearing protection, respirators, safety gloves, and safety glasses.
Can I use the 6845 alongside a SparkPlugs dispenser to offer worker choice?
Yes. Deploying a Pura-Fit 6845 alongside a SparkPlugs 6605 PlugStation at the same entry point satisfies OSHA's requirement to offer a variety of hearing protector types. Workers who prefer multi-flange choose SparkPlugs; those preferring foam choose Pura-Fit.
Pura-Fit in Multi-PPE Environments
Production workers using both hearing protection and other PPE simultaneously — respirators, safety glasses, or hard hats — benefit from earplugs that require no external hardware. Pura-Fit inserts entirely within the ear canal, creating zero interference with respirator face seals, safety glasses temples, or hard hat suspension systems. This is an advantage shared with all PlugStation earplug formats but is worth noting explicitly for the high-volume primary-station context of the 6845: workers at busy production-line entry points are typically already wearing or about to don additional PPE, and the Pura-Fit draws and inserts without removing other equipment. The smooth skin also reduces the friction that can occur when a rough-surface foam earplug catches on a respirator head strap during donning or doffing sequences, which safety professionals in integrated multi-PPE programs consistently cite as a minor but meaningful daily irritant that the Pura-Fit smooth skin eliminates.

Pros & Cons
Pros
- 500-pair capacity roughly halves refill frequency vs. the 250-pair 6844 at the same draw rate, cutting maintenance-round labor at primary stations
- NRR 33 is the highest attenuation tier available in foam, leaving generous derated margin even in 100+ dB stamping and chipping environments
- Smooth-skin Pura-Fit foam reduces mid-shift friction discomfort, which is the leading cause of earplug discard and lost compliance in long-shift programs
- Individual pair dispensing keeps plugs hygienic and supports per-location accountability documentation for hearing conservation records
- Latex-free lime-green foam suits latex-sensitive workers and aids foreign-material detection in food and pharma streams
- Inserts fully within the ear canal, so it stacks cleanly under respirators, safety glasses, and hard hats with no external hardware to interfere
Cons
- Higher cost per pair than an EcoStation hopper or a commodity bulk box - the individual-dispensing premium only pays off where hygiene or accountability matter
- Uncorded only, so it is a poor fit for intermittent-removal tasks or drop-sensitive environments where a corded plug like the 6900 prevents loss
- Single-use foam means no washing or reuse - recurring consumable cost continues for the life of the program
- Real-world protection is far below the printed NRR 33 once NIOSH/OSHA derating is applied, so the headline number oversells unverified field attenuation
- Channel is model-specific to Pura-Fit refills, locking the station to one earplug type unless you deploy a second dispenser
Who It's For
Buy it if:
- High-traffic primary production entry points where 60-100+ pairs are drawn per day and infrequent refills are an operational priority
- Hearing conservation programs that need comfort-driven NRR 33 to sustain all-shift wear compliance with long-duration foam plugs
- Food processing and pharmaceutical facilities needing hygienic individual dispensing plus lime-green foreign-material visibility
- Multi-PPE workers wearing respirators, safety glasses, or hard hats who need a plug with zero external hardware
- Safety coordinators standardizing on Pura-Fit across primary 500-pair and secondary 250-pair stations for consistent insertion technique
Look elsewhere if:
- Low-traffic or secondary stations where a 250-pair 6844 or a bulk box is more cost-appropriate and 500-pair capacity is wasted
- Workers who repeatedly remove and re-insert plugs and need a corded format to prevent drops and contamination
- Budget-driven programs prioritizing lowest cost per pair where an EcoStation hopper or commodity bulk dispensing is acceptable
- Workers whose discomfort is pressure-related rather than friction-related, who are better served by an ultra-low-pressure plug than by Pura-Fit

Frequently Asked Questions
Is the 6845 Pura-Fit's NRR 33 actually higher protection than a typical NRR 29 foam plug in practice?
On paper yes, but the field gap is smaller than the label spread. After NIOSH 25% foam derating, NRR 33 yields roughly 16.5 dB versus about 14.5 dB for NRR 29 - a real but modest 2 dB. The bigger advantage of choosing the 6845 is consistent insertion: a well-seated NRR 29 plug outperforms a poorly inserted NRR 33 plug. See what is nrr noise reduction rating explained for the math.
How do I decide between the 6845 Pura-Fit and a corded Pura-Fit dispenser?
Choose the uncorded 6845 for continuous-wear stations where plugs go in at shift start and stay in. Choose a corded format like the moldex 6900 pura fit corded when workers remove plugs frequently between tasks or work over machinery and product streams where a dropped plug is a contamination or loss risk. Same NRR 33 foam, different retention strategy.
Is foam like the 6845 the right call, or should this station use reusable flanged earplugs instead?
Foam suits high-volume open access where you accept single-use consumable cost for maximum comfort range and no cleaning burden. Reusable flanged plugs from the reusable earplugs range lower per-day cost for assigned individual users but require washing and personal accountability, which is harder to manage at a shared 500-pair dispensing station. For a shared primary entry point, foam is usually the better operational fit.
Does NRR 33 mean the 6845 over-protects workers in moderate noise?
It can. Over-attenuation that drops effective exposure well below 70 dB can isolate workers from alarms and speech, encouraging plug removal. In 85-90 dBA environments a lower-NRR plug may give better situational awareness while staying compliant. Use how to calculate the nrr you need to confirm NRR 33 is warranted before standardizing on this dispenser.
How does the 6845 compare to using earmuffs at the same station?
Foam plugs like Pura-Fit attenuate more in low frequencies and stack under hard hats and respirators without strap conflict, but rely on correct insertion. Muffs are faster to don and easier to verify visually but interfere with other headworn PPE. Many programs offer both; see ear plugs vs ear muffs to decide which belongs at this entry point.
Is the 6845's per-pair cost worth it over a generic bulk foam dispenser?
It is worth it when individual-pair hygiene, comfort-driven compliance, or per-location accountability matter - the premium buys lower discard rates and cleaner records. If the station only needs lowest cost per pair and you accept higher discard, a commodity bulk box wins. Match the format to whether your program is optimizing for compliance or for unit cost.
Will the smooth-skin Pura-Fit really improve compliance over the rough foam we currently stock?
In long-shift continuous-wear settings, yes - the smooth skin reduces the surface friction that drives mid-shift discomfort and removal, which is the most common compliance leak in foam programs. It does not change NRR 33, so you gain comfort at the same attenuation. The effect is largest where workers wear plugs 8-10 hours without removal.
Which workers should NOT be switched to the 6845 Pura-Fit?
Workers whose discomfort is pressure-related rather than friction-related won't benefit from smooth skin alone and need a lower-expansion plug. Workers who remove plugs constantly are better on a corded format. And small or large ear canals that don't seal on cylindrical foam may need a flanged plug from the reusable earplugs line for a reliable fit.
How does the 6845 fit into a broader hearing protection program?
As the high-volume foam anchor at primary stations. Pair it with corded and metal-detectable options for specialized areas and muffs for double protection above 105 dB. Browse the full hearing protection range to round out station types, and stock the foam ear plugs category for refills and alternatives.
Is the 6845 the highest-protection earplug option, or are there stronger choices?
NRR 33 is the top of the practical foam range - there is no widely available foam plug with a higher single-number rating. For exposures that exceed what NRR 33 can derate to safely, the answer is dual protection (plug plus muff), not a higher-NRR plug. Compare the field against the highest nrr ear plugs guide before assuming you need more attenuation.
Does the 6845 require fit verification, and how is that different from just trusting NRR 33?
The printed NRR 33 is a laboratory ceiling, not a guaranteed field result. Real protection depends entirely on each worker rolling down and seating the plug correctly. Train insertion technique and consider periodic fit checks rather than relying on the label. The how to insert foam earplugs guide covers the roll-pull-hold method that determines whether workers actually get NRR 33.
For a multi-station rollout, how do I choose between Pura-Fit and Moldex SparkPlugs?
Pura-Fit is single-use roll-down foam optimized for comfort and disposal volume; SparkPlugs are reusable multi-flange plugs that some workers prefer for repeated insertion without rolling. Offering both at an entry point satisfies the expectation that workers get a choice of protector types. Compare the moldex 6604 sparkplugs before deciding which earns the primary slot.
Is the 6845 a good value compared with buying Pura-Fit in bulk boxes?
The dispenser carries a capacity and convenience premium over loose bulk boxes of the same moldex 6800 pura fit plugs. You pay more per pair but gain hygienic single dispensing, reduced contamination, lower discard, and easier refill logging. For an unsupervised high-traffic station the dispenser typically pays for itself in compliance and waste reduction; for a supervised low-traffic bench, loose bulk may be cheaper.
How does the 6845 compare to the corded Softies or SparkPlugs corded for shared stations?
Corded plugs like the moldex 6654 sparkplugs corded or moldex 6650 softies corded trade a little NRR for retention and visibility - useful where dropped plugs are a hazard. The uncorded 6845 maximizes comfort and capacity for continuous wear. Pick corded for intermittent or overhead-product tasks, uncorded for all-shift seated or stationary work.
Should a metal-detection-required line use the 6845 or a metal-detectable plug?
The 6845's lime-green foam aids visual foreign-material detection, but it is not metal-detectable. Lines with metal-detection critical control points should standardize on a metal-detectable plug such as the moldex 6615 sparkplugs metal detectable so a lost plug fragment is caught by the detector. Reserve the 6845 for areas where visual detection alone meets your contamination SOP.
