Copperline Mask Testing
Please note, the following testing has been made available so you can adjudicate for yourself the efficacy of the Copperline Mask. We are making no therapeutic claims.

Further Testing
The below summaries and actual results are all based on testing the Copperline Mask with the Anti-Dust HEPA filter attached (unless specified).
Note that the active copper is contained within the Copperline Mask as a knitted thread and NOT in the Anti-Dust HEPA filter.
The Copper Mask contains 3 protective layers - when adding the Anti-Dust HEPA filter it adds another 3 - all up these are results with tests inclusive of 6 layers.
The Copper Mask solely worn is effectively rated at KF80 - filteration 80% of ~0.3μm particles. Helpful against aerosol & droplet particle transmission in day to day settings, all day - everyday even without the Anti-Dust HEPA filter. The filtration has been tested according to European Standards - with Paraffin Oil, rather than US Standards (with salt) which simulate better liquid protection.

According to Nelson Labs USA, the most relevant testing criteria for general use masks are:
- Bacterial & Viral Filtration Efficiency (BFE/VFE)
- Particle Filtration Efficiency (PFE)
- Respirator Precertification Tests – NIOSH
- Surgical Face Masks and General-Use Masks – ASTM F2100 & EN 14683
