Moldex 6845 Pura-Fit PlugStation Review: 500-Pair Earplug Dispenser (NRR 33)
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.
