Buying Guide: Centrifugal Bathroom Extractor Fans
- Airflow needs: For small bathrooms (up to 45 sq ft), 50 CFM is often enough; for larger rooms up to about 100 sq ft, aim for 100–110 CFM; rooms over 120 sq ft may require 130 CFM or more.
- Noise levels: Look for units under 1.5–2.0 sones for quiet operation during early mornings or nights. Higher CFM can mean a slight noise increase.
- Installation: Check duct size (commonly 4 inches), attic access requirements, and whether the housing supports no-cut or retrofit installation.
- Power and efficiency: Energy Star ratings are a plus for energy-conscious homes. Consider long-term energy use and motor quality.
- Compatibility: If replacing an existing motor, verify shaft diameter, mounting studs, and blade compatibility with your current housing.
- Integrated features: Some models offer built-in lighting or detachable ducts. Weigh convenience against potential increases in installation complexity or heat load.
