Buying Guide
How much airflow do you need?
- Small bathrooms (<45 sq ft): 50 CFM models are usually sufficient.
- Medium bathrooms (45–100 sq ft): 80–110 CFM options provide better moisture control.
- Large or rooms with high humidity: 110 CFM or higher can reduce fogging more effectively.
How important is noise?
- Low-noise models (≤1.0–1.5 sones) are ideal for bathrooms adjacent to bedrooms.
- Higher airflow often trades some extra noise; balance needs with layout and occupant tolerance.
Do you want lighting or filtration?
- Lighted fans: An integrated LED light can replace a separate bathroom light but adds electrical considerations.
- Charcoal filtration: Helpful in cooking-adjacent bathrooms or spaces with persistent odors, but requires filter replacement.
Installation considerations
- Compact housing and NO CUT installations simplify retrofits in tight ceilings.
- Duct size (4-inch is common) and duct routing impact performance and noise.
- Electrical wiring: Some models require simple wiring updates; others clip into existing circuits.
Choosing by space type
- Small powder rooms: prioritize compact size, quick install, and low noise.
- Medium baths: prioritize balance of airflow and quiet operation; consider 80–110 CFM.
- Bathrooms with lingering moisture: consider higher CFM and optional filtration or timed operation features.
