Buying Guide
What to consider when choosing a 110 CFM exhaust fan for your bathroom:
- Noise level: Look for 1.0 Sones or lower for the quietest experience; note that a slightly higher Sone can still feel quiet in larger, acoustically challenging bathrooms.
- Room size and airflow: For spaces around 100 square feet, 110 CFM is typically sufficient; larger rooms may require multiple units or higher CFM models.
- Installation type: Ceiling-mounted units fit most bathrooms, but retrofit capable models can simplify replacing old fans without attic access.
- Ducting compatibility: Most models use a 4-inch duct; confirm your existing duct size and ensure proper duct routing to avoid bottlenecks.
- Mounting depth and opening: Some models have slim housings to fit tight joist spaces; measure opening to ensure a proper fit.
- Energy efficiency and certifications: ENERGY STAR certification can indicate lower operating costs over time and better efficiency.
FAQ

What installation should I expect for a 4-inch duct?
A 4-inch duct is standard for most 110 CFM fans. Ensure duct length, bends, and insulation are appropriate to preserve airflow and avoid backpressure.
