Can I compare products when one publishes full performance curves and the other publishes only a peak result?

Can I compare products when one publishes full performance curves and the other publishes only a peak result?
The company publishes its filtration measurement size by size across the measured range on the NanoFlashing™ page, and each headline value on the Ultrafine Particles and Wildfire Smoke pages is stated with what it measured.
The size-by-size table on the NanoFlashing™ page names no report. The smoke and ultrafine-particle reports named 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 Report 6847, ASHRAE 52.2 with Appendix J. LMS Technologies' Pine-Needle Smoke Report LMS#10471 of 20 October 2025 measured single-pass fractional efficiency in an ASHRAE 52.2 test duct. Report 6847 is on a 24 × 24 × 30 in. pocket filter; a rating belongs to the construction that was tested. The published position is that 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.
