Does evidence from a fresh smoke exposure apply to aged smoke transported over long distances?
A result belongs to the article and the conditions that were tested.
The Terms of Use state: “A reported result describes only what the identified test found.” They also state: “A test of C-POLAR material, a component, or a prototype does not establish the performance of a finished product that incorporates it. Construction, processing, storage, wear, cleaning, other components, and actual use may change the result.” and “Use evidence, specifications, instructions, and warnings specific to the actual finished product and use.”
What can be checked on any filter is the charge. The polarity is a positive electric charge at rest. It is measured as surface charge density, in nanocoulombs per square centimetre. The charge is measured on every production run, and the measurement can be repeated on any filter, upon request.
The company’s published smoke testing used real smoke from burning pine needles: the Validation page names LMS Technologies, Report LMS#9904, 28 April 2025, 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 the Statement of Classification cites LMS Technologies, Pine-Needle Smoke Report LMS#10471, 20 October 2025, which compared a pleated air filter of Aeropro media with C-POLAR against the same media without it. A published result belongs to the article that was tested, under the conditions named in the report that recorded it.
