Ensuring Proper Air Flow in Your Bathroom

Having the right air circulation in your bathroom is essential for a healthy and comfortable atmosphere. The amount of air movement is usually measured in cubic feet per minute (CFM). Generally, it is recommended to have eight air changes per hour, which would equate to one CFM per square foot of bathroom area. For instance, a 7 foot x 10 foot bathroom would require a 70 CFM fan.

A rating of at least 50 CFM is suggested for bathrooms that are 50-square-meters or smaller. If the bathroom is larger, then additional ventilation capacity will be needed. The Home Ventilating Institute (HVI) provides guidance on determining the appropriate ventilation rates for both large and small bathrooms through intermittent or continuous ventilation. Most bathroom fans are quite simple, but some have extra features such as motion sensors that turn on the fan when you enter the bathroom and turn it off when you leave.Mold in the bathroom can be caused by a leak in the pipes, but stained stains on wall or ceiling surfaces often indicate inadequate ventilation and too much moisture in the air.

To prevent this, you can open the window if possible or keep the bathroom door open slightly while showering and then open it completely once you're done.The table below can be used as a guide to ensure proper air flow in your bathroom:.
