Buying Guide: Key Considerations For Retrofits
- Airflow needs: Match CFM to room size. 1 CFM per square foot is a common baseline; larger or moisture-prone baths may require higher CFM (80–110).
- Noise level: Look for units rated around 1.0–1.5 sones for quiet operation without compromising ventilation.
- Retrofit compatibility: Check housing depth and joist space. Many models fit within 2×6 joists or require minimal drywall cuts.
- Attic access: Attic-free installation simplifies remodels and reduces structural modification work.
- Integrated lighting: If lighting is desired, consider fans with built-in LED lights or compatibility with retrofit lighting modules.
- Energy efficiency: ENERGY STAR-rated models offer efficiency benefits and potential long-term savings.
- Maintenance accessibility: Choose designs with accessible housings and straightforward blade cleaning, especially in humid bathrooms.
