Previously available only in commercial locations such as spas and luxury hotels, the 18-by-24-inch, wafer-thin defogging system has a self-adhesive backing that enables it to be installed easily on the back of any wall-hung mirror. Pre-attached power leads connect to your home's electrical system. When activated, the defogger transmits warmth across the mirror's surface, preventing the formation of distorting moisture.
The Clearly You system, available from WarmlyYours, a Long Grove, Ill.-based manufacturer of electric floor heating systems, draws 75 watts of power and operates at a regulated temperature of 104 degrees. It will not affect the mirror's reflective coating and can be wired for continuous operation (with costs of a few cents a month, according to the manufacturer). It's priced at $85.
