Bathroom Exhaust Fans: How Important Are They?

Bathroom Exhaust Fans: How Important Are They? Is your bathroom fan really doing its job? Studies found that noisy bathroom exhaust fans in many residential spaces move very little air while consuming a great amount of energy. Sadly, many homeowners in Crestwood, Missouri, are not aware that their bathroom fans are a potential culprit in their homes if they are not working properly. What are bathroom exhaust fans designed for? Bathroom exhaust fans are essential components of your home’s ventilation system. They are designed to improve your home’s indoor air quality and eliminate excess moisture and humidity that can contribute to mold growth. Take note that your bathroom is one of the major sources of moisture where condensation and mold may build up. A bathroom that’s not well ventilated is at risk of structural damage. Why? The exhaust fan is where the moisture from shower should set off. If the fans are not working, the moisture may penetrate into the attic insulation, structural seams and wall, resulting to structural damage due to mold growth. This is why it is important to keep your bathroom dry and maintain a well-designed ventilation system through the exhaust fans. Testing the efficiency of an exhaust fan How efficient is your current bathroom exhaust fan? Do not assume that when a fan makes a disturbing noise it is moving the air outdoors. Some fans are completely ineffective though they seem to operate properly. If you have doubts about your bathroom exhaust fans, it might be time for a replacement. Here are factors to consider when choosing a new exhaust fan for your bathroom.
  • Airflow Rate
Based on the guidelines provided by the Home Ventilating Institute (HVI), proper ventilation in bathrooms require an exhaust of one cubic foot per one square foot of the area. Say for instance, an 80 square feet bathroom would have an 80 cm airflow requirement.
  • Sound Level
Some homeowners do not turn on their bathroom exhaust fans because they are too noisy. But if they do not operate, they are not useful either. To check the fan’s sound level, you need the HVI rating. According to them, the exhaust fan should not have a sound rating of over 1.5 sones.
  • Energy Efficiency
You should look for an energy-efficient exhaust fan which consumes no more than 180 watts. Opt for those with Energy Star Fan logo for best energy savings.
  • Aesthetics
It’s also important to look at the aesthetics of the exhaust fan when looking for one. Make sure that it fits your bathroom’s design and décor.
