Bathroom ventilation is one of the most important means of ensuring good indoor air quality throughout your home. When it is properly installed, it removes stale or moist air in the bathroom and sends it to the outdoors. Learn more about the benefits of bathroom exhaust ventilation.
How Bathroom Ventilation Improves Indoor Air Quality
The bathroom is generally a small, rather confined space. Without ventilation, the air is inclined to stay in the bathroom and become stale, allowing airborne pollutants to build up. Among the major offenders:
- dust mites
- pet dander
- volatile organic compounds (VOCs)
The bathroom is also a site of high relative humidity. Moisture from showering, flushing, and running water in the sink can create overly moist conditions that lead to mold. The moisture may also invade the rest of the home and raise the humidity level there so that, in the summer, the home’s occupants feel uncomfortable enough to lower the thermostat.
What’s more, unpleasant odors can linger in the bathroom unless the air is exhausted.
A bathroom exhaust ventilation fan will do wonders by removing the polluted air and moisture and sending it outdoors.
Installing Bathroom Ventilation Fans
Your bathrooms may have been built without ventilation, or the fan may have stopped working or doesn’t work properly. Some people don’t even bother to turn these fans on because they are noisy and annoying.
When you plan to replace or install a new bathroom fan, make sure that the exhaust duct goes through the roof to the outdoors. You do not want moist air going into your attic or amidst the ceiling joists.
Get the right size fan to remove air in sufficient volume from your bathroom. Measure the length by width by height and divide by 5 for the cubic feet per minute (cfms) the fan should move.
Cost of exhaust fans goes up the quieter they are. Fans are rated in sones, with a sone of 4 being noisy, and a sone of 1 very quiet.
