How could NanoFlashing be used in masks?
C-POLAR and NanoFlashing™ questions, with the company’s answers and the sources they come from.
Last reviewed: .
All questionsWhat fit, filtration and workplace-use evidence applies to the complete product independently of the material claim?
The nearest record is on the material: The Open University of Hong Kong, Test Report IRITS2020007030001R1, 7 June 2021, ASTM F2101, a bacterial filtration efficiency test; it is a material test, not a fit or workplace result. A copy may be made available on our review of the request.
The Terms of Use state that, as of their effective date, the Water, Textiles, Food packaging, and Medical devices chapters describe Research Applications, and that they do not describe finished products currently available from C-POLAR for those uses. What the Textiles chapter publishes is the material: the NanoFlashing™ Textile has a permanent positive polarity, a fixed positive charge, and the fabric stays waterproof, breathable, strong and washable.
The Terms of Use state: “Each reported result belongs to the C-POLAR material, component, or prototype that was tested.”
Fit testing, filtration testing of a complete mask and workplace protection factors are evidence about a finished respirator, and they are held by whoever makes and certifies that respirator, because the company offers no respirator, mask or insert; what the company holds is the material record named above.

All questionsIs the claimed function intended for inhaled air, exhaled air or both?
A filter acts on the air that passes through it, and it does not reach a surface or a source.
NanoFlashing™ is passive. It generates no ozone, releases nothing, and adds nothing to what passes through. The company offers no respirator, mask or insert. What it states is the property and what it does in a filter: NanoFlashing™ attracts negatively charged particles through electrostatic attraction, and the filter captures airborne particles mechanically and by electrostatic attraction. The Terms of Use state that, as of their effective date, the Water, Textiles, Food packaging, and Medical devices chapters describe Research Applications, and that they do not describe finished products currently available from C-POLAR for those uses.
