The introduction of AS 16890 marks a turning point in how Australia evaluates and specifies air filtration. While it draws its foundation from the international ISO 16890 series, this modified version is not a copy-paste. It is a deliberate evolution that adapts global test methods to the demands of local industry, regulation, and climate.
From ISO to AS: Why Modify a Global Standard?
ISO 16890 introduced a welcome shift in air filter testing. Rather than relying on grades, it classifies filters based on their efficiency at capturing PM1, PM2.5 and PM10 particles, aligning with the same metrics used in public health and environmental policy.
But the ISO standard, as adopted in many countries, is essentially a test protocol. It does not require construction criteria, does not reference independent test validation, and does not enforce minimum local compliance. In short: it tells you how a filter performs in a lab but says nothing about how that data is verified, or what materials the filter is made from.
Enter AS 16890.
What Makes the Australian Adaptation Different?
AS 16890 is Australia’s modified adoption of ISO 16890 and those modifications matter. Here’s how:
- Accredited Testing Is Mandatory
All test data must come from an ILAC-accredited laboratory. This ensures test results are:
Independently verified
Repeatable
Traceable to a recognised quality system
In other words, filters sold under the Australian Standard aren’t just labelled, they’re proven.
- Published Data Must Be Transparent
Manufacturers must publish the date of testing and test data must match the filter sold. - Minimum Marking Requirements
All filters must be clearly and permanently labelled with manufacturer identity and performance rating making specification and compliance easier for facility managers, engineers, and regulators. - Supports Local Safety Expectations
AS 16890 doesn’t just reflect how a filter performs; it supports how it should be used in Australian systems, referencing the local HEPA filter standard AS 4260 and maintaining compatibility with AS/NZS ISO 9001 systems.
Why It Matters
By strengthening ISO 16890 with accreditation, transparency, and local relevance, AS 16890:
Protects public health with verified PM removal performance
Supports Australian industry by recognising filters tested under local conditions
Prevents regulatory capture, where imported products flood the market without equivalent safety or construction scrutiny
And crucially, it restores confidence. End users no longer need to guess whether a filter lives up to its brochure. Under AS 16890, performance isn’t claimed, it’s certified.
AS 16890 and AS 1324: Working Together
It’s important to understand that AS 16890 doesn’t replace everything. Where ISO 16890 falls short, particularly in construction safety, fire resistance, and fibre shedding, AS 1324 still applies. In fact, both standards are now referenced in the National Construction Code, each serving different but complementary roles.
AS 16890, Verified test performance (PM efficiency, under controlled conditions)
AS 1324, Construction, durability, and safety standards (including washable, renewable, and viscous filters)
Together, they ensure Australia’s air filters aren’t just technically efficient, they’re fit for purpose.
