Tech Drive Very-Quiet 70 CFM With LED Light
Airflow: 70 CFM; Noise: 2.0 sones; Light: 11W LED module, 600 lumens, 4000K. This ceiling-mounted unit replaces many small bathroom fans via a standard ceiling opening. It’s well-suited for bathrooms up to 75 square feet and includes an integrated LED light grille.
Best for: bathrooms needing quiet operation with a bright, neutral daylight-like LED. Better for spaces where ceiling depth is sufficient. Choose this if you want a straightforward installation and a single-cabinet look without separate fixtures.
Caution: Housing height is 6 inches; ensure ceiling depth accommodates this height when replacing older, shallower units.

Airflow: 70 CFM; Noise: 1.5 Sones; Light: 800 lumens with 3 selectable color temperatures (3000K/4000K/5000K). The integrated grille design combines light and exhaust for a cohesive appearance. Recommends separate switches to control fan and light for flexibility.
Best for: those who want adjustable ambiance and a brighter overall bathroom light. Better for users who prefer choosing warm, natural, or cool lighting to fit time-of-day mood.
Caution: Changing color temperature requires turning the wall switch off and on within 3 seconds; ensure wiring and switches are compatible with two-control setups.

Airflow: 80 CFM; Noise: 0.9 Sones; Light: 1000 lumens with 5 selectable color temperatures (2700K–5000K). This model emphasizes quiet operation with a high-lumen light output and adjustable color tones for different bathroom tasks.
Best for: bathrooms where quiet operation matters more than ultra-slim installation; good for spaces needing bright, consistent illumination. Choose this if you want strong moisture control with flexible lighting.
Caution: Larger lumen output may draw more power; verify dimming or switch options align with room wiring.
Broan-NuTone 744 Recessed Light Ventilation Fan

Best for: spaces needing adjustable airflow along with a dimmable light for gradual lighting. Better for retrofit projects where attic access may be limited and flexible installation is essential.
Caution: Requires proper wiring to support dimmable LED and multi-CFM options; check compatibility with existing switches and dimmers.
Air King DRLC701 Round Bath Fan With Light
Airflow: 70 CFM; Noise: 4.0 sones; Light: Frosted glass lens with bronze grille. This decorative unit offers a stylish finish with separate wiring for fan and light control, providing flexible operation.
Best for: bathrooms where appearance matters and a bronze finish complements decor. Avoid if ultra-quiet operation is a priority, as this unit is louder at higher settings.
Buying Guide
What should you look for when choosing a 70 CFM exhaust fan with light?
- Noise level vs. airflow: A lower sone rating indicates quieter operation. If your bathroom is often used while others are sleeping, prioritize models with 1.5 Sones or less.
- Light quality and control: Consider LED brightness (lumens) and color temperature options. Color temperature (2700K–5000K) affects ambiance; separate switches may help control light and fan independently.
- Installation requirements: Check housing depth, duct size (3″ or 4″), and whether attic access is needed. Some units install entirely from the room ceiling, which simplifies replacement.
- Airflow adequacy: For bathrooms up to 75 square feet, 70 CFM generally suffices. For damp spaces or longer ducts, verify that the unit maintains airflow under duct losses.
- Durability and certifications: Look for ETL or FCC listings and energy efficiency ratings (such as Energy Star where available) to ensure reliability and compliance.
Frequently Asked Questions
