Buying Guide
What size should you install?
For most bathrooms up to 80 square feet, 80 CFM is appropriate. If your space is larger or has high humidity, consider a higher CFM or multiple fans. Measure ceiling cutouts to ensure the housing and grille fit.
Noise level matters. How quiet is quiet?
Fan noise is measured in sones. Values around 0.8–1.0 sones are very quiet and suitable for bedrooms adjacent to baths. 1.5 sones remains acceptable for many bathrooms, while 2.0+ sones may be noticeable.
Do you want lighting with ventilation?
LED-integrated models provide light and airflow in one unit, useful for primary bathrooms and powder rooms. If you already have ceiling lighting, a dedicated ventilation-only model may be preferable to avoid higher costs and complexity.
Installation considerations
Look for roomside installation features, no attic access requirements, and compatible duct sizes. Ensure the housing depth fits your ceiling and that the opening is standard (approximately 7.6″ x 7.3″ or close).
Energy efficiency and certifications
Energy Star-certified models help reduce energy use. UL or ETL certification indicates compliance with safety standards. If long-term running costs matter, prioritize these ratings.
Practical selection tips
- Choose the lowest Sone rating that meets your moisture-control needs for quiet operation.
- Prefer models with standard 4-inch ducting for flexible installation options.
- If you need light, select LED-equipped models; otherwise, a ventilation-only unit can save space and complexity.
