Freshen Up Your Bathroom with a New Ventilation Fan – Part 2

As mentioned in Part 1, if the air in your bathroom remains moist or stale too long even with the fan running, it’s probably time to install a new ventilation fan. In addition to preserving the structural condition of your bathroom, there will be health benefits because humidity and moisture in an enclosed bathroom create the ideal conditions for the growth of mold and mildew, which are known to cause respiratory, nervous system, allergy, and mental health issues. Part 2 will cover a bathroom ventilation fan’s important features. To obtain the best results, consult with a licensed electrician regarding your options and installation.

Capacity of Air Flow

Measured in cubic feet per minute (cfm), bathroom ventilation fans will vary in airflow capacity. By using the guidelines provided by the Home Ventilating Institute, you will be able to determine the needed capacity for your bathroom. Typically, 1 cfm for every square foot of bathroom floor space is necessary. An additional 50 cfm per toilet,

50 cfm per shower, 50 cfm per bathtub, and 100 cfm per whirlpool will be needed by bathrooms larger than 100 square feet.

Level of Noise

For fan noise, the unit of measure is the sone, which indicates degree of loudness. Extremely quiet fans have a rating from 0.5 to 1.2 sones. A rating of 1.5 to 2.0 sones is considered very good. Noisy fans will have a rating exceeding 4.0 sones.

Smart Features

Smart features available include motion sensor activation, which will turn on a fan, along with overhead lighting, when an individual enters the bathroom. Another option is presetting the fan on low volume for the removal of moisture from minor activity like brushing teeth, and then activating it by switch for high-volume activity like showering.

Models equipped with a low-wattage night light promote safety at night. In addition, there are fans activated by sensors that detect high humidity. For cold nights, fans with built-in heaters provide warmth.

Energy Efficiency

Using about 60% less energy, Energy-Star rated bathroom ventilation fans are certified independently by either the Home Ventilating Institute or the Air Movement and Control Association. For some fans, the quiet motors that allow near silent functioning are also designed for energy efficiency.
