What MERV or ISO rating does the NanoFlashing filter have?

The ratings published on cpolar.tech are MERV 15A and ISO ePM1 70%, each on the pocket filter that was tested.

LMS Technologies, Report 6847, 5 November 2024, tested a 24 × 24 × 30 in. pocket filter under ASHRAE 52.2-2017 with Appendix J and rated it MERV 15A. Eurovent Certita Certification, Certificate 15.06.011, certified a ten-pocket filter at ISO ePM1 70% under ISO 16890. Both ratings are held on pocket filters made by VOLZ Filters, one of the manufacturing partners named on the company's About page, and not on a flat panel filter. LMS Technologies, Report LMS#9904, 28 April 2025, is a single-pass fractional efficiency test on a 24 × 24 × 2 in. pleated air filter in an ASHRAE 52.2 test duct, in accordance with standard LMS aerosol test procedures, and it is not the report that records MERV 15A. As the company's Validation page puts it, industry standards ASHRAE 52.2 Appendix J and ISO 16890 test electrostatic filters after their temporary charge is removed, showing how they perform without it. A rating belongs to the construction that was tested and to the conditions in the report, and neither rating carries over to a panel filter, to another size or to another product. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory. NanoFlashing™ is a technology; the name, rating and sale of a product that carries it are set by that product's maker and seller, and cpolar.tech publishes no HEPA rating.
