Moldex Respirator Models — Disposable Range

Moldex-Metric Disposable Filtering Facepieces · N95 · N99 · N100 · R95 · P100 · Assigned Protection Factor 10

How do you read a Moldex respirator model number?

Short answer: the number is the platform, the letters are the protection. A Moldex respirator model such as 2700N95 breaks into two halves — 2700 tells you the shell shape, the strap system and whether it has a valve, and N95 is the NIOSH filter class, the only part of the code that describes how much the filter captures. Get the letters right first, because that is the compliance question, then use the number to pick the version people on your crew will actually keep on their faces.

Twenty-one Moldex disposables sit in this collection, spanning N95, N99, N100, R95 and P100. What follows is the pattern as it holds across that range — it is an observed regularity in the catalog rather than an official naming specification published by the manufacturer, so treat it as a reliable reading aid and confirm the class letters on the product itself.

What do the leading digits mean?

They identify the platform — the shell, the strap, and whether air leaves through a valve or back through the filter.

• 22xx — flat-fold. Folds flat for pocket carry and opens into a three-panel shape. The 2201N95 is the small version.
• 23xx — molded cup with an exhale valve. The traditional dome. The 2307N95 is the low-profile build and the 2310N99 steps the filter class up to N99.
• 24xx and 25xx — nuisance-level relief plus a valve. The 2400N95 carries organic vapor relief and the 2500N95 carries acid gas relief. Read the section below before you buy either.
• 26xx — HandyStrap, unvalved. The strap drops down so the mask hangs at your neck between tasks instead of going in a pocket. The 2601N95 and 2607N95 are the low-profile pair.
• 27xx — HandyStrap plus a valve. The 2700N95 is the core model in the range.
• 28xx — HandyStrap, valve, and a nuisance carbon layer. The 2800N95 is a 2700 with the carbon added — one digit apart, and the difference is not a protection difference.
• 4xxx — AirWave. A different filter geometry that folds the media into a wave to increase surface area within the same footprint. The 4200N95, 4600N95 and 4800N95 run the same progression as the 2000 series.

What do the trailing digits and the M prefix tell you?

Three sub-patterns run through the range consistently enough to rely on.

A trailing 1 means small. The 2201N95, the 2601N95 and the 4701N100 are all the small builds of their platforms. Sizing is not cosmetic on a tight-fitting respirator — a mask that cannot pass a fit test in your size provides no assigned protection at all, so see our respirator sizing guide.

A trailing 7 means low profile. The 2307N95 and 2607N95 both carry it. Low profile matters where you also wear safety glasses or work close to a surface, because a deep cup pushes eyewear off your face.

The 40 ending marks the R95 build of the same platform. The 2740R95 is the R95 version of the 2700, and the 2840R95 is the R95 version of the 2800. Same shell, same strap, oil-resistant media.

An M prefix is the black Special Ops finish. The M2600N95, M2700N95, M2800N95 and M4600N95 map one-to-one onto their unprefixed counterparts. The finish is the difference.

Which NIOSH class do the letters mean?

This is the half of the code that describes protection, and it is certified under NIOSH 42 CFR Part 84. The letter is about oil resistance and the number is filter efficiency against the most-penetrating particle size.

• N — not resistant to oil. Fine for dust, metal fume, mineral particulate and most construction work.
• R — resistant to oil for a limited period. The 2740R95 and 2840R95 are the R-series members; see N95 versus R95.
• P — oil proof. The 4400P100 is the P-series member here.
• 95, 99, 100 — 95, 99 and 99.97 percent efficiency. The 4700N100 and 2310N99 are the high-efficiency N-series options; see P100 versus N95.

One thing the letters do not tell you: how much protection you are assigned. Under the OSHA table in 29 CFR 1910.134 every disposable filtering facepiece is assigned a protection factor of 10, whether it is an N95 or a P100. Moving up the filter classes improves efficiency and oil resistance and leaves that number untouched — our assigned protection factors reference covers what does change it.

What does nuisance-level relief actually do on a 2800 or 4800?

It reduces odor. That is the whole claim, and it is worth stating plainly because the numbering makes this the easiest mistake to make in the entire Moldex range: a 2700 and a 2800 differ by one digit, and the extra digit buys a thin carbon layer with no NIOSH-rated gas or vapor class attached to it.

NIOSH certifies particulate filters. It does not assign a protection class to nuisance-level organic vapor or acid gas relief, so a 2800N95 is an N95 that smells better in a solvent-adjacent environment — not a respirator with vapor protection. If you have measurable solvent vapor or acid gas exposure, the answer is a cartridge on a reusable facepiece, which is a different product class entirely. Our page on nuisance relief versus rated protection sets out the line, and the reusable range sits in Moldex half mask respirators with media in Moldex cartridges and filters.

Should you choose a valved or unvalved Moldex respirator?

Valved, for most industrial work. The valve vents warm moist air on the exhale instead of pushing it back through the filter and up past your nose, which lowers heat build-up and cuts the fogging that makes people lift a mask to see what they are doing. A mask that gets lifted mid-task is not protecting anyone.

Unvalved has one decisive advantage and it is not comfort: a valve releases unfiltered exhaled air, so an unvalved model is the choice anywhere you also need to protect other people or a clean product from what the wearer breathes out. That is why the M2600N95 exists alongside the M2700N95. Our comparison of valved versus unvalved goes through the cases, and cup versus flat-fold covers the shell decision.

How do the main Moldex disposables compare?

Pack sizes vary sharply across these listings — dispensers, boxes of twelve or twenty, and singles all appear — so compare cost per mask rather than the headline figure. The spread between the 4700N100 and the 4400P100 is largely a pack-quantity difference rather than a protection difference.

Which Moldex models are not on this page?

Two that you may well be looking for. The 2200N95 and the 2300N95 are the brand's two best-known disposables and they are reviewed on this site, but they sit in Moldex N95 respirators rather than in this grid. If you arrived looking for either, those links go straight to them, and Moldex 2200 vs 2300 compares them directly — the short version being that the 2300 is the valved one.

Also outside this collection by design: the reusable 7000 and 8000 series half masks, the 9000 series full facepiece, and every cartridge and filter that fits them. Those are a different product class with a different assigned protection factor — a full facepiece is 50 against the 10 that applies to everything here. They live in Moldex full face respirators and the half-mask collection linked above.

Editor's pick: the 2700N95 — the HandyStrap drop-down and the valve are the two features that decide whether a disposable survives a full shift, and this is the model that carries both without paying for a carbon layer that provides no rated protection. Take the 2740R95 instead where oil mist shares the air.

Our methodology: what is on this page, and what it cannot do

We counted this collection against the storefront rather than trusting the heading: twenty-one Moldex disposables, every one of them correctly filed, every one priced. The numbering patterns above were derived by comparing the twenty-one member titles against each other rather than recalled from a manufacturer document — each pattern holds across at least two products in the range, and we say so instead of presenting an inferred rule as an official specification. NIOSH classes are reported exactly as certified, nuisance-level relief is never counted as a protection class, and assigned protection factors come from the OSHA table rather than product copy. Where a model you might be searching for is on this site but not in this grid, we link it and say where it lives instead of substituting the nearest thing that is here.

Moldex Disposable Respirator FAQ

How do you read a Moldex respirator model number?

The leading digits identify the platform — shell shape, strap system and whether there is a valve — and the letters after the number are the NIOSH filter class. So 2700N95 is the HandyStrap valved cup platform with an N95 filter.

What is the difference between a Moldex 2700 and a 2800?

One digit and one carbon layer. The 2800 is a 2700 with nuisance-level organic vapor relief added. That layer reduces odor and carries no NIOSH-rated gas or vapor class, so it is not a protection upgrade.

What does the M prefix mean on a Moldex respirator?

It marks the black Special Ops finish. The M2600N95, M2700N95, M2800N95 and M4600N95 map one-to-one onto their unprefixed counterparts, with the finish as the difference.

What is the Moldex AirWave?

The 4000 series platform, which folds the filter media into a wave to increase surface area within the same footprint. The 4200N95, 4400P100, 4600N95, 4700N100, 4701N100 and 4800N95 are all AirWave builds.

Does a Moldex P100 protect better than a Moldex N95?

It filters better — 99.97 percent against 95 percent, plus oil resistance — but both are assigned a protection factor of 10 under the OSHA table, because that number comes from the facepiece rather than the filter.

What does a trailing 1 mean in a Moldex model number?

Small. The 2201N95, 2601N95 and 4701N100 are the small builds of their platforms. Size matters on a tight-fitting respirator because a mask that cannot pass a fit test in your size provides no assigned protection.

What does nuisance level organic vapor relief do?

It reduces odor using a thin carbon layer. NIOSH assigns it no protection class. If you have measurable solvent vapor exposure, you need a rated cartridge on a reusable facepiece, not a disposable with nuisance relief.

Should I buy a valved or unvalved Moldex respirator?

Valved for most industrial work, because it vents heat and moisture and reduces the fogging that makes people lift a mask. Unvalved where you also need to protect other people or a clean product, since a valve releases unfiltered exhaled air.

Is the Moldex 2200N95 in this collection?

No. The 2200N95 and 2300N95 are reviewed on this site but sit in the Moldex N95 respirators collection rather than this one. Both are linked above.

What is the difference between the Moldex 2200 and 2300?

The 2300 has an exhale valve and the 2200 does not, and the 2200 is a flat-fold while the 2300 is a molded cup. Neither is a member of this collection.

Do Moldex disposables need a fit test?

Yes. Every model here is tight-fitting, so it requires a fit test for the specific make, model and size, and a clean seal against skin. Facial hair crossing the sealing surface disqualifies it.

Are the Moldex 7000 and 9000 series on this page?

No. The 7000 and 8000 series are reusable half masks and the 9000 series is a full facepiece — different product classes, and the full facepiece is assigned a protection factor of 50 rather than 10. They sit in their own collections.

Where a Moldex respirator fits against the rest of the range

Everything on this page is disposable, which sets both its convenience and its ceiling. A moldex n95 disposable needs no cleaning, no cartridge inventory and no maintenance record, and it is assigned a protection factor of 10. A moldex face mask in the reusable 7000 series is also assigned 10, so it buys seal consistency and cost per shift rather than more protection. Only a full facepiece takes you to 50. Searches for moldex airwave land on the 4000 series covered above, and moldex n100 on the 4700 and 4701. For the wider disposable market across brands see disposable respirators and N99 and N100 respirators, and for the R95 pair on their own Moldex R95 respirators. Fit testing applies to all of them — see the fit testing guide and OSHA 29 CFR 1910.134.

Why trust WC Safety on Moldex respirators?

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. This page decodes a numbering system rather than ranking a grid, and it does two things a brand page is not obliged to do. It tells you that the step from a 2700 to a 2800 costs more and adds no rated protection, because the carbon layer is an odor feature that NIOSH does not classify. And it tells you that the two Moldex disposables most people are searching for, the 2200N95 and 2300N95, are not in this collection at all — then links them where they actually live rather than steering you to something that is here. Where the numbering rules are inferred from the catalog rather than published, we label them as such. Standards referenced are NIOSH 42 CFR Part 84 and OSHA 29 CFR 1910.134.
