Moldex Earplugs

92 Moldex Hearing Protectors · NRR 20–33 · Foam, Reusable, Metal-Detectable · Corded & Cordless

Which Moldex earplugs should you choose?

Short answer: pick the family first. For maximum attenuation in disposable foam, the Moldex Pura Fit family at NRR 33 is the workhorse — the cordless Moldex 6800 is the reference pack. Where a dropped plug must be found, SparkPlugs add metal detectability at the same NRR 33. For a softer, smaller fit try Meteors, and for reusable flanged plugs the Rockets and Jetz sit at NRR 27.

Editor's pick: Pura-Fit 6800 — NRR 33 is the top of the scale and the tapered foam suits the widest range of ear canals, which matters more than the last decibel because a plug that will not seat does not deliver its rating.

Our methodology: how this collection was curated

We record the NRR exactly as Moldex states it and never average or round between families. Where a product is a dispenser, a refill for a dispenser, or a plain box, we say which — because several product codes differ in nothing else, and the distinction decides whether what arrives is usable on its own. Metal-detectable and moisturizing variants are identified as such rather than folded into the general foam listings, and we do not present a competitor's model as an alternative on a brand page.

Moldex Earplugs (2026)

Moldex makes hearing protection in families — Pura-Fit, SparkPlugs, Meteors, Softies, Glide, Mellows, Camo Plugs, Goin' Green, Zebras, Soothers in disposable foam, and Rockets, Jetz, Alphas and BattlePlugs as reusable flanged plugs. Ninety-two of them sit in this collection, spanning NRR 20 to 33. Under OSHA 29 CFR 1910.95, hearing protection is required once an eight-hour time-weighted average reaches 85 dBA, and the employer must offer a choice of protectors. The NRR itself is an EPA-labelled laboratory figure, and NIOSH is clear that real-world attenuation is typically lower — which is why fit and consistency matter more than chasing the highest number on the box.

What this collection covers

• Disposable foam, NRR 33 — the bulk of the range: Pura-Fit, Meteors, Softies, Zebras, Camo Plugs and Goin' Green.
• Metal-detectable — SparkPlugs, NRR 33, for food and pharmaceutical lines where a lost plug must be found. See metal detectable ear plugs.
• NRR 30 and 31 — Glide twist-in plugs and Mellows at 30, Glide Soothers at 31, plus the moisturizing Soothers at 33.
• Reusable flanged, NRR 27 — Rockets, Jetz, Alphas and Glide Trio. See reusable earplugs.
• Dual-mode — BattlePlugs and Flip-to-Listen, which switch between a closed high-attenuation setting and an open setting that lets speech through. Replacement tips are stocked separately.
• Dispensers and refills — PlugStation, EcoStation and TouchFree wall stations, in 150 to 750-pair capacities, with matching refills. See ear plug dispensers.

Moldex family comparison

How to choose between moldex spark plugs, Pura-Fit and the rest

Are you buying a dispenser, a refill, or a box?

Check this before anything else, because it is the easiest thing to get wrong in this range. Many Moldex codes differ only in packaging: a wall station and its own refill can be one digit apart, and a station holding 750 pairs sits beside a 750-pair refill bag that has no station in it. Buy the refill first and you have loose plugs and nowhere to mount them; buy a second station and you have paid for hardware you already own. The product handle in the address bar is the most reliable place to read this — it spells out whether an item is a dispenser or a refill, which station family it belongs to, and how many pairs are in the pack.

Does a higher NRR always mean better protection?

No, and over-protection is a real problem rather than a theoretical one. The NRR is a laboratory figure and NIOSH advises that field attenuation is usually lower, so real protection depends far more on whether the plug is rolled down and inserted deeply enough than on the last three decibels. Worse, a plug that cuts too much makes speech and warning signals hard to hear, and people respond by leaving one ear out — which is much worse than a correctly-worn NRR 27. Match the rating to the measured exposure; our guide to calculating the NRR you need works through the arithmetic.

Foam or reusable?

Foam wins on attenuation and on cost per use where plugs go in once and stay in for a shift — Moldex foam reaches NRR 33 and reusables top out at 27. Reusable flanged plugs win where people go in and out of noise repeatedly, because they can be inserted with dirty hands without contaminating foam that has to be rolled between fingers, and they wash. Many sites issue both. Disposable vs reusable covers the trade-off, and corded vs cordless the other axis.

When do you need metal-detectable plugs?

Wherever a lost plug entering the product stream is the hazard — food processing, beverage, pharmaceutical and some cosmetics lines. SparkPlugs carry an embedded metal element so an inline detector catches them, at the same NRR 33 as the standard foam. If your facility has metal detection on the line, the small extra cost is not really optional.

What are dual-mode plugs for?

Intermittent noise where you still need to hear speech or signals. BattlePlugs and Flip-to-Listen switch between a closed setting around NRR 24 and an open setting that passes conversation, so the wearer is not choosing between protection and communication by taking a plug out. They are reusable, and BattlePlugs tips are replaceable in three sizes.

Fit, hygiene and replacement

Insertion is where the rating is won or lost. Foam plugs must be rolled to a thin crease-free cylinder, inserted while pulling the ear up and back, and held until they expand — a plug sitting in the outer ear delivers a fraction of its rated attenuation. Reusable flanged plugs need the same ear-pull but no rolling, which is why they suit dirty hands.

Replace foam plugs when they are soiled or no longer expand crisply, which for most users is daily. Reusables should be washed with mild soap and water, dried, and retired when the flanges lose their spring or tear. Do not share plugs between people, and do not carry loose foam in a pocket — grit picked up there ends up in the ear canal.

Moldex earplugs FAQ

What is the highest NRR Moldex earplug?

NRR 33, which several families reach — Pura-Fit, SparkPlugs, Meteors, Softies, Zebras, Camo Plugs, Goin' Green and Soothers. That is the top of the NRR scale for earplugs.

How do I tell a dispenser from a refill?

Read the product handle in the address bar — it states dispenser or refill, the station family, and the pack size. Codes one digit apart can be a station and its own refill, so this is worth checking before ordering.

What is the difference between Pura-Fit and SparkPlugs?

Both are disposable foam at NRR 33. SparkPlugs add an embedded metal element so a lost plug can be caught by an inline metal detector, which matters on food and pharmaceutical lines.

Are Moldex Rockets reusable?

Yes. Rockets, Jetz and Alphas are reusable flanged plugs rated NRR 27, washable and suited to going in and out of noise repeatedly.

Does a higher NRR always mean better protection?

No. The NRR is a laboratory figure and field attenuation is usually lower, so fit matters more. Over-protection also masks speech and warning signals, which leads people to remove a plug entirely.

What does moldex plugstation mean?

PlugStation is one of Moldex's wall-mounted dispenser lines, alongside EcoStation and TouchFree. They hold between 150 and 750 pairs and take matching refills.

What are BattlePlugs?

Dual-mode reusable plugs with a closed setting around NRR 24 and an open setting that lets speech through, for intermittent noise where communication still matters. Replacement tips come in three sizes.

How do I insert foam earplugs correctly?

Roll to a thin crease-free cylinder, pull the ear up and back, insert, and hold until the foam expands. A plug resting in the outer ear delivers far less than its rated attenuation.

When do I need metal-detectable earplugs?

On food, beverage, pharmaceutical and similar lines where a lost plug entering the product is the hazard and inline detection is in place. SparkPlugs cover this at NRR 33.

Can Moldex reusable plugs be washed?

Yes — mild soap and water, dried before reuse. Retire them when the flanges lose their spring or tear, and never share plugs between people.

What NRR do I actually need?

It depends on your measured eight-hour exposure. OSHA requires hearing protection above an 85 dBA time-weighted average; the right rating is the one that brings exposure under the limit without cutting so much that you cannot hear signals.

Are corded or cordless plugs better?

Corded plugs stay with the wearer between uses and are easier to find if dropped; cordless are lighter and avoid a cord catching on equipment. Moldex offers most families both ways.

Why trust WC Safety on hearing protection?

WC Safety reviews workplace PPE full-time as an independent affiliate site — we do not sell products, hold no inventory, and accept no paid placements. On a brand page that means two things. We report each family's NRR exactly as Moldex states it and say plainly that a laboratory NRR overstates field performance, rather than treating 33 as a promise. And we flag the packaging trap in this range honestly: dispensers, refills and plain boxes share near-identical naming, and we would rather tell you to check than let you order a refill for a station you do not own. Standards referenced are OSHA 29 CFR 1910.95 and NIOSH hearing-loss prevention guidance. Reviewed by Steven Eaton, WC Safety editor. Last reviewed: July 2026.
