AirWeave: 99% Protection Face Masks by AusAir

Do you ship overseas?
Not all of our items are available for international shipping at the moment. For those that are, we've indicated in the section above with a little note. Please bear with us as we work to bring more products to you globally.

How are your face masks classified?
Globally, there are many different standards for face masks. Our masks have been thoroughly tested and are classified below:

US: ASTM-F3502-21 Barrier Face Coverings
EU: CWA 17553:2020 Community Face Coverings
UK: BSI Flex 5555 Community Face Coverings
CN: T/CSTM 00387-2020 Daily Reusable Protective Mask

What tests have the masks undergone?
Particle Filtration Efficiency (PFE)
Our tests have been completed by FDA registered and ISO 17025 accredited Nelson Labs, the leading global provider of microbiological laboratory testing for MedTech and pharmaceutical companies.
Our filter media has been tested against a particle size of 0.1μm (microns) and received an average filtration efficiency of 99.50%. Click HERE to view the report.

Bacterial Filtration Efficiency (BFE)
Our filter media has been tested in compliance with ASTM F2101-19 and EN 14683:2019, Annex B. The filter media received a bacterial filtration efficiency greater than 99.80%. Click HERE to view the report.

Viral Filtration Efficiency (VFE)
Our filter media has been tested in compliance with US FDA good manufacturing practice (GMP) regulations 21 CFR Parts 210, 211 and 820. The filter media received a viral filtration efficiency of 99.99%. Click HERE to view the report.

Copper Infused Anti-microbial Fabric
We have received additional test results for the copper-infused antimicrobial material which we use to make the carry bag. We sent this material for independent testing to ensure it meets a high standard of antimicrobial performance. STS is a leading independent testing agency and is accredited ISO17020:2012, the highest qualification level of inspection bodies. Click HERE to view STS Copper Infused Anti-Microbial Bag Report.

- Staphylococcus aureus (ATCC 6538) >99%
- Escherichia coli (ATCC 25922) >99%
- Candida albicans (ATCC 10231) 98%.

Are your masks medical devices?
AirWeave masks are not defined as medical devices and are to be used for source control only. Different regions have different standards, requirements and product classification systems for non-medical masks.

Do your masks meet N95, KN95, EN149, FFP2, FFP3, KF94 or AS1716 certification?
There are various international standards all of which have differences in their test design and methodology. AusAir's products are certified by FDA registered and ISO 17025 Nelson Labs using ASTM-F2299 standards. The test has been customised to make it more akin to real life use, most notably using non-neutralised particles.

AirWeave filters have achieved over 99% filtration efficiency using particles sized PM0.3. Why this particle size? PM0.3 is the most penetrative particle size (MPPS), meaning it represents the worst case scenario. Larger particles such as PM2.5 or smaller particles such as PM0.1 will be therefore have a higher filtration efficiency than 99%.

How do I wash the mask?
The outer skin can be washed like an item of clothing. Machine wash using cold soapy water. We recommend rinsing the stainless steal valves and silicone components by hand. We do not recommend washing the filters as this will affect filtration performance, rendering them ineffective.

You can also hand or machine wash the carry bag.

How do I know when to change my filter?
For high levels of pollution and for over 3-6 hours of daily use, we have found our filters are effective for around 2 weeks. There is no exact formula for how long the filter will last, however we recommend replacing the filter once breathing through the filter becomes increasingly difficult or the filter is visibly dirty for hygiene reasons.
