Yes. The fabric and the mask in its entirety has been tested according to ASTM standards – a peak international technical standardising body recognised and utilised by many organisations and health industries.
These tests have been carried out:
AATCC 100-1012 (Antibacterial Fabric Test)
ASTM F2299-2003 (Standard Test Method for Determining the Initial Efficiency of Materials Used in Medical Face Masks to Penetration by Particulates Using Latex Spheres)
ASTM F2101-2019 (Standard Test Method for Evaluating the Bacterial Filtration Efficiency (BFE) of Medical Face Mask Materials, Using a Biological Aerosol of Staphylococcus aureus)(modified)
Particle Filtration Efficiency (PFE)
All test results from The Taiwan Textile Research Institute (TTRI) and Korean Textile Inspection and Testing Institute (KOTITI) can be found here.
It filters 80% and 99% of an average of ~0.6-0.3μm particles at a rating of up to KF80 (P1) and exceeding KF94 (P2 including the Anti-Dust HEPA filter) respectively - with fine dust particles, 99% ~0.3 microns.
With these results, backed by evidence based studies on Copper as a textile incorporated material - we stress to our customers: be informed of the meaning of the findings and purchase with an informed decision.
Please note that we are still in the process of gaining Australian approval for use in health/medical fields as well as wide ranging industries but at this stage recommend this product for general use only.
We do not claim to prevent virus/disease. We are cautious however, to provide tests that show favourable results using this fabric which is incorporated in the Copper Mask - and future Copper Yarn Knitted Products and encourage customers to read over these results with regards to particle filtration efficiency.
