Episode notes
HEPA Filters' Trade-off Problem
- HEPA filters remove 99.97% of particles but resist airflow, lowering efficiency in room air cleaning.
- Removing slightly fewer particles from more air can deliver more clean air overall than HEPA filtering alone.
Choose High CADR and Low Noise
- Prioritize air purifiers with high clean air delivery rate (CADR) and low noise.
- Avoid running purifiers at low settings due to noise, which drastically reduces airflow and effectiveness.
Use Standardized Filters
- Avoid air purifiers with custom filters that are expensive to replace.
- Prefer purifiers using standardized filters with competitive markets to reduce long-term costs.
