PRODUCT REVIEW
In-Depth U.S. Market Review
The ROJOSAN Smart Bathroom Exhaust Fan aggressively targets the premium segment of the U.S. smart home market by combining multiple high-end features into a single unit: powerful ventilation (230 CFM) , a quiet operation (1.0 Sone), an integrated Bluetooth Speaker , and a crucial Humidity & Odor Sensor . This fan is designed for homeowners with larger bathrooms or those in high-humidity climates (like the South or Pacific Northwest) who require superior, automated moisture control paired with modern connectivity and entertainment.
The defining feature of this ROJOSAN fan is its unprecedented 230 CFM airflow paired with a quiet 1.0 Sone rating, making it one of the most powerful and quiet options available. While other fans offer smart control, the inclusion of a dedicated Odor Sensor —in addition to the humidity sensor—is a unique differentiator. This makes it an ideal, high-performance smart exhaust fan with humidity sensor for any large or high-traffic master bathroom.
Technical Analysis
| Specification | Detail & U.S. Context | Analysis |
| Airflow Rate (CFM/Sones) | Powerful 230 CFM / Quiet 1.0 Sone. | The 230 CFM rate is suitable for very large master bathrooms (up to 230 sq ft), offering superior ventilation. The 1.0 Sone ensures it remains very quiet despite the high power. |
| Smart Sensing | Built-in Humidity Sensor and Odor Sensor (VOC) . | Provides advanced, automated control. The fan can turn on based on moisture or the presence of common bathroom odors (Volatile Organic Compounds). |
| Control Methods | App Control, Voice Control (Alexa), and Dedicated Remote Control. | Offers a versatile control suite, allowing for scheduling, hands-free operation, and simple physical access for all household members. |
| Audio | Integrated Bluetooth Speaker. | Allows for music and podcasts to be streamed directly to the ceiling, providing entertainment without cluttering the counter with a separate speaker. |
| Lighting | Integrated LED Light (Color/CCT details not specified, but is included). | Provides necessary functional lighting, complementing the unit's focus on ventilation and smart control. |
| Automation | Auto-On Functionality based on Sensor Triggers. | The most critical feature: the fan operates autonomously to maintain air quality without user intervention, ensuring maximum efficiency. |
1. Extreme Ventilation Power and Quiet Performance
The 230 CFM rating positions this fan as a professional-grade solution for the residential market. This high volume of airflow is necessary to effectively clear moisture from large, high-ceiling master baths that exceed the typical 100 sq ft standard.
Despite this powerful performance, the fan maintains a remarkable 1.0 Sone noise level. This means you get the necessary high-volume air turnover without the loud, disruptive drone, making it the quietest powerful exhaust fan on the U.S. market.
2. Advanced Humidity and Odor Sensing
The dual-sensor system is what truly defines this as a smart device. The Humidity Sensor is a standard, essential feature that automatically turns the fan on when moisture levels spike (e.g., during a shower).
The added Odor Sensor (often measuring VOCs—Volatile Organic Compounds) means the fan can also respond to common bathroom smells, automatically activating to maintain superior air quality without you having to remember to turn it on. This is a significant convenience feature for modern American homes.
3. Comprehensive Smart Control
The App, Voice (Alexa), and Remote Control options ensure full usability. The app is necessary for setting the sensor thresholds, reviewing performance, and creating schedules.
The Alexa voice control provides hands-free convenience, and the dedicated remote ensures that operation is always possible, even if the Wi-Fi or smartphone is unavailable. This multi-modal control offers the best of both automated and manual operation.
User Profiles
