Buying Guide: Key Considerations For Choosing A Bathroom Fan
- Room size and airflow: Match CFM to bathroom square footage (rough guide: 1 CFM per sq ft for typical bathrooms; larger baths may need 80–110 CFM).
- Noise level: Sones indicate perceived loudness. If privacy and peace matter, target 1.5 sones or lower for most homes.
- Light integration: Consider fans with built-in LED lighting for fewer fixtures and simpler wiring.
- Installation: Check attic access, ceiling space, and duct routing. No-cut or retrofit options save time in existing homes.
- Odor control: Charcoal or additional filtration helps in spaces with cooking or heavy moisture exposure.
- Energy efficiency: ENERGY STAR certified units typically offer better efficiency and long-term cost savings.
- Maintenance: Plan for filter replacement (where applicable) and motor kit compatibility for future upgrades.
