GROWNEER Bathroom Exhaust Fan With Humidity Sensor
This model integrates a 1800W heater with an exhaust fan and a humidity sensor. The heater has built-in overheat protection that stops heating when temperatures exceed safe levels. The humidity sensor can be set to 30%, 60%, or 80%, allowing the fan to automatically start when the selected relative humidity is reached. The unit offers 110/160 CFM performance at around 1.0 sone, suitable for bathrooms up to about 160 sq. ft. Lighting options include selectable color temperatures (2700K/4000K/5000K) and a nightlight, and it comes with a remote for convenience. These combined features target both moisture control and occupant comfort in colder conditions.
Broan-NuTone BHFLED110 PowerHeat Bathroom Exhaust Fan
The Broan-NuTone BHFLED110 combines an exhaust fan, heater, and LED light. Its 110 CFM fan removes moisture and odors while the heater provides supplemental warmth. The unit operates at about 2 sones, which is louder than some ultra-quiet models but still common for heater-equipped combos. The LED is dimmable and offers multiple color temperatures (2700K, 3500K, 5000K). The fan, light, and heater functions operate independently or together, giving flexible control over ventilation and heating. The grille design is intended for broad compatibility with modern bathroom decor.
VIVOHOME AutoFlow Bathroom Exhaust Fan With Humidity Sensor

The VIVOHOME AutoFlow fan emphasizes constant airflow technology and an EC motor for efficiency and long life. It automatically shifts airflow between 30, 110, and 160 CFM based on humidity levels: low background ventilation below 50% RH, mid-level at above 50%, and high-power mode above 80%. This three-speed AutoFlow design maintains consistent performance even with duct bends or partial blockages. The motor is brushless EC for up to 50% energy savings versus standard AC motors. While this model doesn’t list an integrated heater, its humidity-responsive airflow control is strong for moisture mitigation in varying bathroom sizes.
Panasonic WhisperValue Ceiling/Wall Mount Exhaust Fan FV-0510VSC1
Panasonic’s WhisperValue fan features a condensation/humidity sensor that automatically starts ventilation when moisture is detected. The Pick-A-Flow switch allows quick selection between 50, 80, or 100 CFM to match room size and noise preference. The unit uses a DC/ECM motor, is Energy Star certified, and is engineered for quiet operation and long-term reliability. It is UL-listed for ceiling or wall installation and includes an L-shaped bracket to simplify mounting. The WhisperValue is focused on efficient, quiet humidity control rather than providing supplemental heating.
OREiN 160 CFM 3-in-1 Bathroom Exhaust Fan With Humidity Sensor
OREiN’s 160 CFM model is a 3-in-1 unit with exhaust, integrated LED light (1500 lm), and a humidity sensor that auto-activates at about 60% RH. It covers 120–160 sq. ft. and operates at approximately 1.0 sone. The light is 3CCT adjustable (3000K/4000K/5000K) with a 2200K nightlight feature. This model prioritizes strong, quiet airflow and lighting versatility for larger bathrooms; it does not include a heater but is designed to clear moisture quickly and reliably.

Tips for Getting the Best HVAC Prices
- Prioritize Quality Over Cost
The most critical factor in any HVAC project is the quality of the installation. Don’t compromise on contractor expertise just to save money. - Check for Rebates
Always research current rebates and incentives — they can significantly reduce your overall cost. - Compare Multiple Quotes
Request at least three estimates before making your choice. You can click here to get three free quotes from local professionals. These quotes include available rebates and tax credits and automatically exclude unqualified contractors. - Negotiate Smartly
Once you've chosen a contractor, use the proven strategies from our guide — How Homeowners Can Negotiate with HVAC Dealers — to get the best possible final price.
Room Size And CFM Requirements
- Calculate Needed CFM: Use 1 CFM per square foot as a basic guideline for ventilation. Larger bathrooms or those with tubs and showers may need higher CFM or multi-speed fans.
- Heater Impact: Heater-equipped combos often pair with mid-range CFM (e.g., 110–160 CFM). Confirm the fan’s airflow meets your area requirements while accounting for duct length and bends.
Humidity Sensor Performance
- Sensitivity And Setpoints: Check available humidity setpoints (common options: 30%, 50%, 60%, 80%). Lower setpoints trigger earlier but may increase run time.
- Auto-On Reliability: Look for units with clear indicators that the sensor is active and proven auto-on behavior in product specs.
Heater Features And Safety
- Wattage And Warm-Up: Higher wattage (e.g., 1800W) heats faster; ensure wiring and circuit capacity match the heater’s requirements.
- Overheat Protection: Built-in thermal cutoffs are important to prevent unsafe operation.
- Independent Controls: Independent fan/heater/light operation provides flexibility and energy savings.
Noise Level (Sones)
- Understanding Sones: Lower sones equal quieter operation. Around 1.0 sone is very quiet; 2.0 sones is audible but typical when heaters are integrated.
- Match To Use: If quiet operation is a priority, favor models with low sones and check whether heater mode increases noise.
Energy Efficiency And Motor Type
- EC/DC Motors: Electronically commutated (EC/DC) motors use less energy and last longer than standard AC motors.
- Constant Airflow Technology: Systems that adjust speed to maintain CFM under changing duct conditions keep performance steady.
Lighting And Additional Features
- Integrated LED Options: 3CCT lighting and dimmable LEDs add versatility; nightlights are helpful for nighttime navigation.
- Remote Or Wall Controls: Remote control or multi-function wall switches increase convenience for timed or scene-based operation.
Installation And Compatibility
- Housing Size & Mounting: Verify housing depth and mounting brackets for retrofit or new construction installation.
- Duct Size: Confirm compatible duct diameter and that the fan’s CFM won’t be significantly reduced by long or obstructed ducts.
Durability, Certification, And Safety
- Certifications: Look for UL/ETL listing and Energy Star where applicable for safety and efficiency assurance.
- Warranty & Service: Manufacturer warranty terms and available support matter for long-term reliability.
Comparison Perspectives
- Heating + Sensor vs. Sensor-Only: Heater+sensor combos offer seasonal comfort, but sensor-only models may be quieter and more energy-efficient.
- CFM Trade-Offs: Higher CFM clears moisture faster but may be louder; multi-speed or AutoFlow designs help balance performance and noise.
- Motor Type: EC/DC motors cost more upfront but save energy and provide longer service life compared to AC motors.
