Moldex 6844 Pura-Fit PlugStation Review: 250-Pair Earplug Dispenser (NRR 33)
WC Safety Editorial Verdict: 4.4/5
WC Safety Editorial Verdict — 4.4/5. The Moldex 6844 Pura-Fit PlugStation earns our recommendation as the smart way to deploy NRR 33 smooth-skin foam at scale: the 250-pair wall-mount dispenser puts a documented comfort alternative within arm's reach of the floor, which is exactly what OSHA 29 CFR 1910.95(i)(3) expects when a worker rejects standard textured foam. The smooth outer skin genuinely lowers insertion friction and skin irritation versus open-cell foam ear plugs, and at the top of the hearing protection range it leaves no protection on the table.
We dock half a point only because the dispenser is a fixed capital purchase that pays off in high-traffic plants but is overkill for a small crew — those buyers are better served by a bulk box or the corded Moldex 6900 Pura-Fit corded.
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.

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.

Pros & Cons
Pros
- Wall-mount PlugStation puts 250 pairs of NRR 33 protection at point-of-use, satisfying OSHA's duty to keep hearing protectors accessible on the floor
- Smooth-skin foam directly answers 1910.95(i)(3) — a documented alternative when a worker finds standard textured foam irritating or uncomfortable
- NRR 33 is at the very top of the foam range, leaving maximum margin after NIOSH 25% or OSHA (NRR-7)/2 derating
- Individually dispensed pairs reduce contamination and waste versus reaching into an open bulk box with dirty hands
- Rounded cylindrical body and low insertion friction make consistent deep seating easier for new or inconsistent users
- Refillable dispenser lowers long-run cost per pair versus repeatedly buying small retail packs
Cons
- The dispenser is a fixed capital cost that only pays off in high-traffic, multi-station facilities — a small crew is overserved
- Uncorded format means dropped or set-down plugs are easily lost or contaminated, unlike a corded version
- Single NRR 33 attenuation can overprotect in moderate (85-90 dBA) areas, hurting communication and situational awareness
- 250-pair capacity needs disciplined refill management or stations run empty and compliance gaps appear
- Smooth skin offers no roll-down texture grip, so very small ear canals may find seating less positive than tapered plugs
Who It's For
Buy it if:
- Facilities running a formal 1910.95 hearing conservation program that need NRR 33 protection accessible at multiple wall stations
- Plants with workers who report irritation or discomfort from standard textured foam and need a documented smooth-skin alternative
- High-traffic, high-headcount operations (90+ dBA areas) where point-of-use dispensing cuts waste and improves consumption tracking
- Safety managers standardizing on one top-tier foam SKU across the site to simplify training and stocking
- Operations wanting to lower long-run cost per pair through a refillable station rather than retail packs
Look elsewhere if:
- Small crews or single-bench shops where a bulk box or pocket pack is far more cost-effective than a wall dispenser
- Workers in moderate 85-90 dBA noise who would be overprotected by NRR 33 and need to stay aware of alarms and speech
- Jobs where plugs are frequently removed and re-inserted, where a corded plug like the Moldex 6900 or 6654 prevents loss
- Teams that prefer reusable flanged plugs and want a washable option from the reusable-earplugs range instead of single-use foam

Frequently Asked Questions
Is the Moldex 6844 PlugStation worth the cost over buying Pura-Fit in a bulk box?
It depends on traffic, not headcount alone. The PlugStation's value is putting protection at point-of-use so workers actually grab a fresh pair instead of skipping or reusing dirty ones — that improves real-world compliance and cuts waste from open foam ear plugs boxes. In a high-traffic plant the dispenser pays for itself in reduced waste and better consumption; for a small crew, a bulk box or pocket pack is the cheaper, smarter buy.
How does the 6844 Pura-Fit compare to Moldex SparkPlugs for the same job?
Both are NRR 33 single-use foam, but the comfort feel differs. Pura-Fit uses a smooth skin aimed at workers irritated by textured foam, while the Moldex 6604 SparkPlugs use a contoured tapered body some users seat more easily. If skin sensitivity drives your choice, Pura-Fit wins; if you want a familiar tapered plug or metal-detectable and corded options, the SparkPlugs family covers more variants.
Should I choose the dispenser version or the corded 6900 Pura-Fit for my workers?
Pick by how often plugs come out. The uncorded 6844 dispenser suits workers who insert once and stay protected for a shift in a fixed area. If your crew removes plugs repeatedly — moving in and out of noise, talking, then re-inserting — the Moldex 6900 Pura-Fit corded prevents the plug from being dropped, lost, or contaminated between uses.
Is NRR 33 too much protection for my noise environment?
Possibly. NRR 33 is the top of the foam range and after derating still leaves a large margin in moderate noise. Overprotection in the 85-90 dBA band can isolate workers from alarms and speech. Run your exposure against the math in our guide on how to calculate the NRR you need — if you only need mid-20s real-world attenuation, a lower-NRR plug or muff may communicate better.
How does smooth-skin foam compare to reusable flanged earplugs for a comfort-sensitive worker?
They solve comfort differently. Pura-Fit's smooth single-use skin reduces canal friction on each insertion, while a flanged reusable plug from the reusable earplugs range avoids roll-down entirely and is washable. Workers who dislike the expanding-foam sensation often prefer flanges; those who want a fresh, low-irritation plug every shift prefer Pura-Fit. Offering both is the most defensible answer under OSHA's alternatives rule.
Will switching to the 6844 reduce the hearing-protection complaints I'm getting about standard foam?
For irritation and itch complaints, often yes — the smooth skin removes the micro-abrasion that rough open-cell foam can cause. It does not fix complaints rooted in overprotection (muffled communication) or poor insertion technique. Pair the switch with a refresher on how to insert foam earplugs so the smooth, low-friction body is seated deeply rather than left shallow.
Is the Pura-Fit a good single standard for a whole site, or should I stock several plug types?
A top-NRR smooth-foam plug is a strong default, but OSHA expects a variety of types so workers who can't tolerate one option have another. Stock the 6844 as the workhorse and back it with a corded plug and a reusable flanged option. Browse the full hearing protection range so your alternatives are genuinely different in form, not just color.
How does the 6844 Pura-Fit dispenser compare to the Moldex Softies line?
Softies are a softer, lower-pressure foam aimed at gentler all-day wear, while Pura-Fit leads on smooth-skin irritation resistance at the same NRR 33 ceiling. If your workers report pressure or fullness, the Moldex 6600 Softies may feel lighter; if they report surface irritation or itch, Pura-Fit is the better-targeted fix.
Does the dispenser format actually improve compliance or just convenience?
Both, and they reinforce each other. A wall-mounted PlugStation removes the friction of finding plugs, which measurably increases the chance a worker grabs a fresh pair before entering noise. That convenience is a compliance lever: protection that is visible and within reach gets used, while protection locked in a supply room gets skipped.
For intermittent noise where workers step in and out, is the 6844 the right pick?
Not the strongest. Single-use uncorded plugs are designed to go in once and stay, so frequent removal means lost plugs and re-inserting contaminated foam. For intermittent exposure, a corded plug like the Moldex 6654 SparkPlugs corded or a banded/muff option is more practical. Reserve the 6844 dispenser for fixed-area, continuous-noise stations.
How do I decide between the 6844 and a higher-capacity bulk SKU of the same plug?
Decide on placement, not just unit price. The dispenser's premium buys point-of-use access and waste control; a bulk box is cheaper per pair but invites contamination and over-grabbing. Many sites run both — dispensers at entry points to noise zones, bulk boxes in the stockroom for refills. Confirm the model and pack you are buying matches the NRR 33 ear plugs standard you have documented.
Is the 6844 a good fit for a metal-detectable food or pharma program?
Standard Pura-Fit is not the metal-detectable choice. If your program requires detectable foreign-body control on the line, use a purpose-built detectable plug such as the Moldex 6615 SparkPlugs metal detectable. The 6844 dispenser is better suited to general industrial, construction, and warehouse settings where detectability is not a control point.
How much real-world protection should I expect from the 6844 versus the labeled NRR 33?
Plan around derated numbers, not the label. NIOSH recommends discounting foam NRR by about 25%, and OSHA uses (NRR-7)/2 for exposure estimates, so a labeled 33 lands in the high teens to mid-20s dB of usable attenuation depending on which method your program uses. Our explainer on what is NRR noise reduction rating explained walks through why fit, not the printed number, drives the result.
Would earmuffs make more sense than the 6844 dispenser for my application?
Earmuffs win where plugs are removed often, where canal irritation persists despite smooth foam, or where consistent fit is hard to enforce — muffs are quick on and off and don't depend on insertion technique. Plugs like the 6844 win on comfort in heat, under helmets, and in tight spaces. Our ear plugs vs ear muffs guide breaks down the trade-offs so you match the form to the task.
If I want the highest-protection foam plug available, is the 6844 the top choice?
It's at the ceiling. NRR 33 is effectively the highest single-number rating foam earplugs reach, so the 6844 is among the most protective single-use plugs you can buy. The differentiator versus other NRR 33 plugs is the smooth-skin comfort, not extra dB. Compare against the field in our roundup of the highest NRR ear plugs before standardizing.
