What you should consider when buying a bath fan or home ventilation system. Steamy mirrors, damp walls and fogged windows. They’re more than annoying. They could indicate developing problems like mold and mildew, ruined insulation, and wood rot. Spot ventilation solutions from Broan clear the air quickly and efficiently, removing potential problems before they invite themselves into your home. Which product is best suited to my application? Take a moment to consider what you’re looking for in a spot ventilation product. Do you want quiet operation, a powerful blower, decorative designs or something that’s virtually invisible? Sones measure the “sound level” of your fan. A Sone is a measurement of sound in terms of comfortable hearing level for an average listener. The lower the Sone value, the more comfortable the environment. Sones are not decibels or volume, but rather how sound is “sensed.” One Sone is half as loud as two Sones, and is equivalent to a quiet refrigerator.
