In the EU, is a NanoFlashing filter a treated article or a biocidal product?

Under Regulation (EU) No 528/2012 the company classifies the filter as neither a biocidal product nor a treated article.

The Statement of Regulatory Status records how the company applies Article 3 of Regulation (EU) No 528/2012 to the filter. C-POLAR does not describe NanoFlashing™ as an antimicrobial treatment, and it states that the filter has not been treated with a biocidal product and does not incorporate one. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. The polarity is a positive electric charge at rest. The filter is passive. It draws no power, and it has no power supply, electrode, lamp or reservoir. The air leaving the filter has had nothing added to it. The filter captures airborne particles mechanically and by electrostatic attraction. The filter is intended to destroy the viruses, bacteria and fungal spores it captures. It destroys them on direct contact with the positive electric charge, by physical means, and only while the organism is captured by the positive electric charge. The filter is not a biocidal product and not a treated article. The Regulation therefore does not apply to the filter. No authorisation, approval, notification or registration under the Regulation is required. No prior decision of any authority is required. The company classifies the filter itself. No authority has approved, registered or endorsed the filter; the company classifies its own article.
