Moldex 6844 Pura-Fit PlugStation Review: 250-Pair Earplug Dispenser (NRR 33)
Moldex 6844 Pura-Fit PlugStation Review: Smooth-Skin Foam Earplugs for Allergy-Prone and Comfort-Sensitive Workers
Standard foam earplugs have a textured, open-cell surface that can harbor irritants and cause discomfort in workers with sensitive skin or foam contact allergies. Moldex designed Pura-Fit earplugs to solve this: a rounded foam earplug with a smooth, skin-friendly outer skin that feels noticeably different from textured foam on insertion and throughout extended wear. The Moldex 6844 Check Price on Amazon → Pura-Fit PlugStation brings 250 pairs of this smooth-skin format to a wall-mount individual dispenser, maintaining NRR 33 protection while addressing the material-sensitivity concerns that cause some workers to resist standard foam plugs.
OSHA 29 CFR 1910.95(i)(3): Employers must provide a variety of hearing protector types when workers indicate that a particular type is causing discomfort. The Pura-Fit smooth-skin design directly addresses this requirement — it is a documented alternative for workers who cannot tolerate standard textured foam.
What Is the Pura-Fit Earplug?
The Pura-Fit is Moldex's smooth-skin foam earplug. The earplug body is a rounded cylinder — not tapered or contoured — with a proprietary smooth outer skin applied over a foam core. This smooth skin:
- Reduces skin irritation: The textured surface of standard foam earplugs can cause micro-abrasion and irritation in sensitive ear canals. The Pura-Fit's smooth skin eliminates this friction vector.
- Makes cleaning less of a concern: Smooth surfaces harbor fewer contaminants than open-cell foam surfaces, supporting reuse across multiple insertions.
- Improves insertion feel: Workers consistently describe Pura-Fit insertion as "slippery" in a positive sense — the plug slides into position with less resistance than rough-surface foam.
- Supports allergen-sensitive programs: While Pura-Fit is primarily a comfort improvement over standard foam, its clean surface reduces contact with particulates and chemical residues that can accumulate on open-cell foam in certain work environments.
Compare to the Mellows earplug (available in the Moldex 6846 PlugStation), which prioritizes ultra-low expansion pressure at a slight NRR trade-off (NRR 30). Pura-Fit achieves NRR 33 — maximum rating — with the smooth-skin comfort improvement but at standard expansion pressure.

OSHA's Requirement to Offer Alternatives
OSHA 29 CFR 1910.95(i)(3) is clear: "Employers shall make hearing protectors available to all employees exposed at or above 85 dB TWA... at no cost to employees, employees shall be given the opportunity to select their hearing protectors from a variety of suitable hearing protectors." This means a single-model program is not fully compliant if workers report discomfort with the provided model.
Deploying a 6844 Pura-Fit PlugStation alongside a SparkPlugs dispenser gives workers a documented choice between multi-flange and smooth-skin foam formats at the same dispense point. This satisfies the variety requirement without additional management overhead — workers self-select the format that they will actually wear consistently.
NRR 33: OSHA and NIOSH Compliance
| Noise Exposure | Effective Exposure (NRR÷2) | OSHA TWA Compliance |
|---|---|---|
| 90 dB | 73.5 dB | Compliant |
| 95 dB | 78.5 dB | Compliant |
| 100 dB | 83.5 dB | Compliant |
| 105 dB | 88.5 dB | Monitor — borderline |
| 110 dB | 93.5 dB | Double protection required |

When to Choose the 6844 vs. the 6845
The Moldex 6845 PlugStation holds 500 pairs of Pura-Fit earplugs — double the 6844's capacity. Choose based on your station's daily draw rate:
- 6844 (250-pair): Secondary stations, visitor/contractor entry points, tool rooms. Ideal when daily draws are under 20 pairs.
- 6845 (500-pair): Primary production-line entry points, high-volume facilities, locations where refill frequency is a labor cost concern.
How to Refill the Moldex 6844 PlugStation
- Depress both front-panel release tabs and open the dispenser door.
- Clear any remaining Pura-Fit pairs from the magazine channel.
- Load Pura-Fit uncorded refill pairs vertically into the channel, flat end leading into the dispense direction.
- Pairs should stack freely without forcing.
- Close the panel until both tabs engage.
- Test-dispense one pair to confirm operation.
- Record the refill event date and pair count in hearing conservation program logs.
PlugStation vs. EcoStation vs. Bulk Box
| Feature | 6844 PlugStation | EcoStation (6706 Pura-Fit) | Bulk Box |
|---|---|---|---|
| Earplug | Pura-Fit smooth-skin | Pura-Fit smooth-skin | Various |
| Dispense method | Individual pairs | Hopper bulk | Open box |
| Hygiene | High | Medium | Low |
| Per-plug accountability | High | Low | None |
| Cost per pair | Higher | Lower | Lowest |

Frequently Asked Questions
What makes Pura-Fit different from standard foam earplugs?
Pura-Fit earplugs have a smooth outer skin applied over the foam core, replacing the rough open-cell surface of standard foam. This reduces skin friction during insertion, feels more comfortable in the ear canal over extended wear, and is less likely to irritate workers with sensitive skin.
What is the NRR of Pura-Fit earplugs?
NRR 33, the same as SparkPlugs, Goin' Green, and Camo Plugs. NIOSH derating (NRR÷2) gives approximately 16.5 dB real-world attenuation.
Are Pura-Fit earplugs latex-free?
Yes. Pura-Fit earplugs are latex-free. The smooth skin coating and foam core do not contain natural rubber latex, making them suitable for workers with latex sensitivities.
How does Pura-Fit compare to Mellows for comfort?
Both are comfort-focused foam earplugs. Pura-Fit (NRR 33) achieves maximum attenuation with a smooth skin that reduces friction. Mellows (NRR 30) prioritizes the lowest possible expansion pressure for workers with ear canal sensitivity or those who find any foam pressure uncomfortable. If NRR 33 is required, Pura-Fit is the comfort choice. If maximum comfort at NRR 30 is acceptable, see the 6846 Mellows PlugStation.
How many pairs does the 6844 hold?
250 pairs. For 500-pair capacity in the same Pura-Fit format, see the Moldex 6845 PlugStation.
Does OSHA require offering multiple earplug types?
OSHA 29 CFR 1910.95(i)(3) requires that workers be given a selection from a variety of suitable hearing protectors when they report discomfort with a provided type. Deploying both a smooth-skin format like Pura-Fit and a multi-flange format like SparkPlugs satisfies this variety requirement.
Can Pura-Fit earplugs be reused?
Yes. The smooth skin surface is easier to clean than open-cell foam. Wipe with a clean, slightly damp cloth and allow to air dry. Replace when the foam body shows deformation, discoloration, or visible soiling that cannot be cleaned.
Is the 6844 wall-mount bracket included?
Yes. The wall-mount bracket is included with the 6844 PlugStation. No additional hardware purchase needed.
How do I insert Pura-Fit earplugs correctly?
Roll the Pura-Fit between clean fingers to compress into a thin cylinder. Pull the outer ear upward and backward, insert the compressed plug into the ear canal, and hold for approximately 20–30 seconds. The smooth skin means the plug slides into position more easily than rough foam — workers often describe needing slightly less hold time.
Are Pura-Fit earplugs NIOSH-listed?
Yes. Moldex Pura-Fit earplugs are NIOSH-listed under 42 CFR Part 84 with NRR 33.
What industries benefit most from the 6844 Pura-Fit PlugStation?
Healthcare-adjacent manufacturing, pharmaceutical production, electronics assembly, and any facility with a documented history of worker complaints about foam earplug discomfort. The 6844 is also appropriate for facilities with documented latex-sensitivity issues in the workforce.
Can the 6844 be refilled with other Moldex foam earplug models?
No. The 6844 PlugStation is designed for Pura-Fit uncorded refill pairs only. Cross-loading other models will jam the dispensing mechanism.
Does the smooth skin of Pura-Fit affect the acoustic seal?
No. The acoustic seal is created by the compressed foam body expanding against the ear canal walls. The smooth outer skin does not reduce this expansion or the resulting seal quality. NRR 33 is maintained with the skin intact.
What is the color of Pura-Fit earplugs?
Lime green. This bright color supports visual compliance monitoring during supervisor inspections, similar to the compliance-visibility advantage of SparkPlugs yellow-green.
How does the 6844 compare to the EcoStation Pura-Fit format?
The 6844 PlugStation dispenses individual pairs (higher hygiene, higher per-pair cost). The Moldex 6706 EcoStation uses a bulk-bag hopper format (lower cost per pair, higher volume, lower hygiene). For primary production lines with high-volume draws, the EcoStation may be more economical. For secondary stations and compliance-focused locations, the PlugStation is preferred.
