How This Helps
Shows which intervention acts on particles, outdoor-air dilution, HVAC compatibility, noise, maintenance, and cost.
Air Cleaner And Ventilation Comparison Criteria
Compare interventions by action type, not by a single air-quality score.
| Criterion | Why it matters | Score as |
|---|---|---|
| Primary target | CO2, particles, gases, and ventilation are different problems | Ventilation / particle cleaning / filtration / source control |
| Sizing basis | Room size, ceiling height, airflow, and occupancy change the answer | Calculated / estimated / unknown |
| Operating reality | Noise, filter life, bypass, and maintenance change compliance | Likely usable / conditional / unlikely |
| Guidance scope | Standards and public-health guidance have boundaries | In scope / partial / out of scope |
Reader Action Paths
The matrix should end with a next step for each reader type, not a generic winner.
- Compare filtration and ventilation as different interventions.
- Keep health claims conservative and source-scoped.
- Show the formula or guidance behind any sizing recommendation.
- Link each row to a deeper article that explains the caveat behind the score.
How To Keep The Matrix Honest
The matrix should not promise health outcomes. It should help readers choose the next measurement, cleaner, filter, or ventilation question to verify.
