# Validation | C-POLAR Source: https://cpolar.tech/validation/ What NanoFlashing™ was tested against, who tested it, and what they found. This is the text of that page, in a form a machine can read. Nothing here is paraphrased, shortened or added to. Last reviewed: 2026-09-13 ## Validation Scroll to see what was tested ## Wildfire Smoke and Ultrafine Particles NanoFlashing™ is built to maintain its polarity through a wildfire smoke event. Conventional electrostatic charges fade in service, dragging performance down with them. The EPA found that just 10 milligrams of smoke can cut a conventional MERV 13 electrostatic filter’s clean-air delivery by [about 95%](https://pmc.ncbi.nlm.nih.gov/articles/PMC9828579/). During the 2025 Los Angeles wildfires, a typical home system could take in that much smoke in roughly two minutes. Two minutes. That is how quickly a conventional electrostatic filter can be challenged during a real wildfire smoke event. In independent testing with real smoke from burning pine needles, NanoFlashing™ captured nearly 92% of ultrafine particles at 16.5 nanometres, far smaller than a coronavirus. 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. - LMS Technologies, Report 9904 - LMS Technologies, Report 6847 - Eurovent Certita Certification, Certificate No. 15.06.011 ## Pathogens Independent testing shows NanoFlashing™ destroys up to 99.99% of a broad spectrum of viruses, bacteria and fungal spores through a physical mechanism. Pathogens and conditions tested, and the institutes that tested them.

Captured microbes remain viable on the filter for weeks to months and are released back into the air, raising outbreak risk and exposing staff during changeouts, while NanoFlashing™ won’t. Since 2020, NanoFlashing™ has been installed in hospitals, airports, banks and universities, and independently measured with MicronView’s 405 nm Bio-fluorescent Air Monitoring System, which distinguishes biological particles from inert dust in real time. 441 Facilities 7 Countries 19 Sites measured ### Public Hospital in Vancouver 12 months, July 2023 to July 2024 Two identical towers were compared, one on conventional medical grade filters and one on NanoFlashing™. Bioaerosols at the NanoFlashing™ supply vent were 95.44% lower. ### Financial Landmark in London 6 months, March 2024 to September 2024 Measured before and after the air handling unit filters were changed to NanoFlashing™. Particulates down 92.1%, bioaerosols down 94.2%, energy down 18%. ### Major International Airport in the US 1 month, August 2025 Measured before and after the air handling unit filters were changed to NanoFlashing™. Particulates down 76.7%, bioaerosols down 86.0%. ### Public University in Melbourne 1 month, October 2024 Measured before and after the air handling unit filters were changed to NanoFlashing™. Particulates down 82.0%, bioaerosols down 85.5%. ## Tested and Certified NanoFlashing™ is certified to OEKO-TEX® Standard 100, Product Class II, the class for products in direct contact with skin. NanoFlashing™ is tested under Good Laboratory Practice to US EPA Health Effects Test Guidelines.
