By using Germicidal Ultraviolet Light, which physically destroys the DNA of microorganisms, our award-winning Violight Countertop Toothbrush Sanitizer and Storage System will sanitize up to four toothbrushes at one time. Violight prevents cross contamination of bacteria from one toothbrush to another, and even accommodates electric toothbrush heads. Its translucent cap lets you know it's working, and it includes a removable drip cup for easy cleaning. With a one-touch start button, auto shut-off, and safety cap that de-activates the light if it's unlocked or removed, this Sanitizer is a must-have for those who are health-conscious.
