A specification sheet does not show how a purifier will perform in a room. We test the complete device under controlled chamber conditions, rather than evaluating only the filter media. Standards including ISO 17025, ANSI/AHAM AC-1, ISO 16890, ASHRAE 241, ISO 16000, and UL 867 guide our CADR, filtration, bioaerosol, VOC, ozone, and by-product studies for product development, claims, and documentation when:
- CADR testing under ANSI/AHAM AC-1 and ISO 29462 compares smoke, dust, or pollen surrogate removal across fan speeds and quiet modes.
- Filtration efficiency studies aligned to ISO 16890 quantify size-resolved particle removal and leakage effects in filters or whole devices.
- Bioaerosol efficacy studies under ASHRAE 241 context measure organism or surrogate reduction in chambers with device-off decay controls.
- VOC, formaldehyde, ozone, and by-product panels aligned to ISO 16000 or UL 867 screen ionizers, UV, PCO, or treated-media designs.
- Gas-phase removal and CFD studies use ISO 16000 or ASHRAE framing to compare sorbents, catalysts, airflow patterns, and sampling locations.
Teams typically contact us when a design decision, supplier comparison, marketing claim, or customer complaint depends on the purifier's measured performance. Before the device arrives, the study plan defines its operating modes, chamber setup, challenge type, controls, and reporting boundaries.
