Does a claimed effect on smoke include its gas phase?

Does a claimed effect on smoke include its gas phase?

The company's published smoke testing is about particles, and it makes no claim about the gas phase of smoke.

The Wildfire Smoke page states that much of wildfire smoke is made up of fine and ultrafine particles, and many carry an electric charge. The filter captures airborne particles mechanically and by electrostatic attraction. The records named under wildfire smoke and ultrafine particles on the Validation page are 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 LMS Technologies, Report 6847, 5 November 2024, ASHRAE 52.2-2017 with Appendix J, on a 24 × 24 × 30 in. pocket filter, and Eurovent Certita Certification, Certificate No. 15.06.011. The smoke report the company's statements cite is LMS Technologies, Inc., Pine-Needle Smoke Report, LMS#10471, 20 October 2025, single-pass fractional efficiency in an ASHRAE 52.2 test duct.

C-POLAR publishes no evidence for a gas or a vapour, and a measurement of particle capture says nothing about a gas. Certificate No. 15.06.011 can be looked up at source in the Eurovent Certita Certification certified product directory.
