Boost Bathroom Ventilation With an Exhaust Fan

Odors, mildew, blistering paint, peeling wallpaper and desilvering mirrors are a few of the conditions that result from poor bathroom ventilation. Many well-intentioned homeowners just crack a window while showering, but in most cases it simply isn’t enough.

One sure way to rid the bathroom of unwanted odors and excess moisture is an exhaust fan. Fans are rated by cfms--cubic feet of air moved each minute. When shopping for a bath fan, look for one with a cfm at least 10% greater than the bathroom’s floor area.

Also, the noise produced by a fan is measured in sones: the lower the sones, the quieter it is.
