As Nzs 1716 Australian Respirator Standard
What is AS/NZS 1716, and what do P1, P2, and P3 mean in Australia?
Published · Last updated
Short answer: AS/NZS 1716 — current edition AS/NZS 1716:2012, reaffirmed 2024 — is the joint Australian and New Zealand standard for respiratory protective devices. It grades particulate filters P1 (≥80% efficiency), P2 (≥94% — the N95's Australian counterpart), and P3 (≥99.95%), and its companion standard AS/NZS 1715:2009 governs selection, use, and maintenance — including the rule that surprises overseas buyers: P3-level protection is only credited when a P3 filter is worn on a full facepiece.
This guide is the Australia/New Zealand leg of our international respirator standards pillar. It is written for Australian and NZ workers and buyers decoding P-class markings, and for North American readers meeting "P2" on spec sheets — the class-by-class translation to NIOSH sits in every section, with the deep comparison in our N95 vs FFP2 vs FFP3 guide.
Why this matters.
Australia has spent the last few years turning respiratory protection into front-page policy: a world-first national ban on engineered stone took effect in July 2024 after a silicosis surge among stone workers, state work-health authorities enforce P2-minimum selection for silica tasks, and bushfire seasons put P2 respirators on the national shopping list summer after summer. Buying to the wrong class — or trusting an unmarked mask — is exactly the failure those rules exist to prevent.
Two standards, one system: AS/NZS 1716 and AS/NZS 1715
The division of labor mirrors the US split between NIOSH certification and OSHA's program rules. AS/NZS 1716:2012 is the device standard: construction, filtration classes, testing, and marking of respirators sold in Australia and New Zealand. AS/NZS 1715:2009 is the selection-and-use standard: hazard assessment, protection-factor selection, fit testing, training, and maintenance. WorkSafe agencies in both countries point employers at the pair through their WHS codes of practice — comparable in role to how OSHA 1910.134 and 42 CFR Part 84 divide the US system, or CSA Z94.4 and NIOSH split the Canadian one.
P1, P2, P3 decoded
| Class | Minimum efficiency | Typical use | Closest NIOSH concept |
|---|---|---|---|
| P1 | ≥80% | Nuisance dusts, mechanically generated particles | No direct class — sits below N95 |
| P2 | ≥94% | Silica and construction dust, welding fume, bushfire smoke — the everyday class | N95 (≥95%) |
| P3 | ≥99.95% | Asbestos work, high-toxicity dusts — credited only on a full facepiece | P100 (≥99.97%) |
The P3 full-facepiece rule
Under AS/NZS 1715, the P3 protection level is only assigned when a P3 filter is used with a full facepiece. Put the identical filter on a half mask and the system credits P2-level protection — the seal, not the media, is the limiting factor. There is no equivalent rule in the US system, where a P100 on a fit-tested half mask keeps its class and the facepiece's protection factor of 10, as our APF guide lays out. It is the single most consequential difference for anyone translating Australian spec sheets, and it is tabulated against OSHA, HSE, and EN 529 numbers in APFs by country.
Certification and marking: what a real AS/NZS respirator shows
AS/NZS 1716 compliance is demonstrated through third-party certification, most visibly the five-tick StandardsMark or an equivalent accredited conformance mark, printed with the license or certificate number alongside "AS/NZS 1716" and the class on the respirator and its packaging. The verification habit is the same one we teach for every system in this hub:
- Find the standard reference — "AS/NZS 1716" plus the class (P1/P2/P3) on the device itself, not just the box.
- Find the certification mark — a recognizable conformance mark with a license number, traceable to the certifier's public register.
- Match device to packaging — class, brand, and model must agree across mask, box, and instructions.
- Distrust bare classes — "P2" printed alone, with no standard reference or mark, is marketing, not certification. The same red-flag logic applies to CE-less "FFP2" masks in Europe, per our EN 149 guide.
Some multinational models are dual-certified and carry both NIOSH and AS/NZS markings; each marking stands on its own certification, and only the local one satisfies the local regulator.
Selection under AS/NZS 1715: protection factors and fit
AS/NZS 1715 tabulates required minimum protection factors by device class and drives selection the same way every system in this hub does: the device's protection factor must cover the ratio between the workplace exposure and the exposure standard. Disposable and half facepieces sit at a protection factor of 10, with full facepieces and powered air-purifying systems credited substantially higher values from the standard's tables — the PAPR guide explains where powered systems fit. Fit testing of tight-fitting facepieces is required, using the same qualitative and quantitative method families covered in our fit-testing guide, and the everyday user seal check applies on every donning.
Safety note: AS/NZS 1715 draws the universal boundary — no filtering respirator, P1 through P3, is permitted in oxygen-deficient atmospheres or IDLH-level concentrations; those environments require supplied-air or SCBA equipment selected by a competent person under the standard's atmosphere-supplying provisions.
The two Australian drivers: silica and bushfire smoke
Silica and the engineered-stone ban
Australia's silicosis crisis in engineered-stone fabrication led to the world-first national prohibition on manufacturing, supplying, processing, and installing engineered stone from July 2024, with WHS regulators simultaneously tightening the crystalline-silica rules that remain for other materials. Respirator selection for silica tasks starts at P2 and escalates — many state codes specify P3 configurations or powered systems for high-exposure tasks. US readers can compare the trajectory with OSHA's construction silica standard and our silica respirator guide.
Bushfire smoke
For smoke particulate, Australian health guidance recommends P2 respirators — the same 94–95% tier as the N95 recommendation in our wildfire smoke hub — with fit determining real-world protection, and valved models easing long wear. Reuse during extended smoke events follows the same logic as N95 reuse.
New Zealand: same standard, own regulator
AS/NZS 1716 and 1715 are joint standards, so New Zealand runs on the same device classes and selection logic, enforced by WorkSafe New Zealand under the Health and Safety at Work Act. For buyers the practical rule is identical on both sides of the Tasman: AS/NZS-certified equipment, class chosen by hazard, fit tested for tight-fitting occupational use.
Worked example: translating a P2 requirement for a US-based program
A US safety manager inheriting an Australian site instruction that reads "P2 half facepiece, fit tested" translates it like this:
- Class translation. P2 ≈ N95 tier (94% vs 95%) — in the US catalog that means a NIOSH N95 disposable such as the 3M 8210, or the valved 3M 8511 for extended wear.
- Protection-factor check. Both systems credit the half facepiece with a factor of 10, so exposure math carries across directly.
- Fit testing. Both systems require it for tight-fitting facepieces; run the local protocol and record it.
- The reverse translation carries a trap. "P100 on a half mask" from the US side does NOT equal "P3" on the Australian side — under AS/NZS 1715 that combination is credited as P2-level protection, and a true P3 requirement means a full facepiece or powered system.
- Buy locally certified. The Australian site buys AS/NZS-marked stock from Australian suppliers; the US site buys NIOSH-marked stock — the models may even be siblings, but the markings are what the regulator reads.

Why trust WC Safety
WC Safety is an independent, affiliate-supported review site. It is not a retailer: it holds no inventory, takes no orders, and earns only from qualifying purchases through clearly marked links — which never changes what a product is rated to do. Standards language is taken from the regulation text directly, and ratings are reported as the manufacturer publishes them. We run no laboratory and perform no testing of our own. Where published sources disagree, we say so and plan on the conservative figure rather than the flattering one.
Our methodology
Figures come from the regulation and the published specification, in that order. Derated numbers are calculated, not estimated. Nothing here is presented as a measured result, because we measure nothing.
