How are permanent-polarity statements reconciled with filter-rating conditioning results without treating different measurements as interchangeable?
The Validation page states: “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. NanoFlashing™ maintains MERV 15A performance under ASHRAE testing, while Eurovent certifies the same filter at ISO ePM1 70%, with an A class energy rating.”
Report 6847 is on a 24 × 24 × 30 in. pocket filter and Certificate No. 15.06.011 on a ten-pocket bag filter, and a rating belongs to the construction that was tested. NanoFlashing™ is a permanent positive polarity engineered into filter media itself. It is a physical property of the filter. A capture standard is not a destruction standard: ASHRAE 52.2 and ISO 16890 measure what a filter takes out of the air, and they say nothing about what happens to what is captured. The two measurements answer two different questions and are not interchangeable.
