One of the best ways to determine if your bathroom fan is working effectively is by measuring the humidity levels in the room. Humidity is the amount of moisture present in the air, and excessive humidity can lead to issues such as mold and mildew growth, as well as damage to your bathroom fixtures and finishes.
There are several methods you can use to measure humidity levels in your bathroom:
- Hygrometer: A hygrometer is a device specifically designed to measure humidity levels. It can provide you with an accurate reading of the relative humidity in the room. These devices are relatively inexpensive and can be purchased at most home improvement stores or online.
- Thermometer with humidity sensor: Many digital thermometers also have a built-in humidity sensor. These thermometers are easy to use and can provide you with both temperature and humidity readings. Simply place the thermometer in your bathroom and check the humidity level whenever necessary.
- Dew point calculation: If you don’t have a hygrometer or a thermometer with a humidity sensor, you can calculate the dew point to get an estimate of the humidity level. The dew point is the temperature at which the air becomes saturated and condensation occurs. When the air in your bathroom is close to or below the dew point temperature, it means the humidity level is high. You can use online dew point calculators or mobile apps to determine the dew point based on the temperature and relative humidity.
Once you have measured the humidity levels in your bathroom, you can compare the readings to recommended levels. The ideal humidity level in a bathroom should be between 30% and 50%. If the humidity level exceeds 50%, it indicates that your bathroom fan is not effectively removing moisture from the air and may need to be replaced or repaired.
Regular monitoring of humidity levels can help you identify any issues with your bathroom fan and take appropriate action to prevent moisture-related problems. It is important to note that humidity levels may vary throughout the day, so it is best to take multiple readings at different times to get an accurate representation of the overall humidity in your bathroom.
Verifying if the fan is exhausting properly

- Check for airflow: Place your hand near the exhaust grille and feel for the presence of air movement. You can also use a tissue paper or a piece of toilet paper and hold it up to the grille. If the paper doesn’t move or barely moves, it suggests that the fan is not effectively exhausting the air. On the other hand, if the paper is forcefully blown away, it indicates good airflow and proper exhaust.
- Inspect the exhaust grille: Take a close look at the exhaust grille for any visible signs of dirt, dust, or debris accumulation. If there is a significant build-up, it can hinder the airflow and reduce the fan’s efficiency. Regularly cleaning the grille can help maintain proper exhaust and improve the overall performance of the fan.
- Check for backdraft: A backdraft occurs when the fan fails to properly expel the air and instead pulls it back into the bathroom. To check for backdraft, you can hold a tissue paper or a smoke source (such as a lit match or incense stick) near the grille. If the smoke is pulled into the grille or if the tissue paper is sucked towards it, it indicates a backdraft, which means the fan is not effectively exhausting the air.
- Inspect the ductwork: Another important aspect to consider is the condition of the fan’s ductwork. Ensure that the ducts are properly connected, sealed, and free from any blockages. Check for any leaks, cracks, or disconnected sections that can compromise the exhaust flow. Any issues with the ductwork should be promptly addressed to ensure optimal exhaust performance.
- Measure the airflow rate: For a more accurate assessment of the fan’s exhaust performance, you can use an anemometer or a handheld airflow meter to measure the airflow rate. The recommended airflow rate for a bathroom fan is around 50-70 cubic feet per minute (CFM), depending on the size of the bathroom. If the measured airflow rate is significantly lower than the recommended range, it may indicate a problem with the fan or ductwork that requires attention.
Verifying if the bathroom fan is exhausting properly is crucial for maintaining good air quality and preventing moisture-related issues. By following these steps and regularly checking the fan’s performance, you can ensure that your bathroom fan is operating efficiently and effectively.
