Enjoy a clear, fog-free view in the mirror, even after the steamiest shower or bath. Using a minimal amount of energy, the ClearlyYouTM Mirror Defogger safely heats the mirror surface to a regulated temperature of 104 degrees to keep moisture from forming on the surface. ClearlyYouTM Mirror Defoggers come ready to install in several shapes and sizes. This 18” X 24” rectangular mirror defogger is ideal for medium-sized mirrors. The self-adhesive backing enables easy application on any wall-hung mirror, and it conveniently connects to your bathroom’s 120V lighting circuit with its pre-attached power leads. Mirror defoggers cannot be installed in a shower.
