According to the Journal of the American Dental Association, “Studies have shown that contaminated toothbrushes not only harbor, but also transmit both viruses and bacteria that cause systemic, localized and oral inflammatory diseases.” This compact device uses proven germicidal UV technology, the same kind trusted to sanitize instruments in hospitals, to eliminate 99.8% of the millions of household germs that can accumulate on your toothbrush, including streptococcus and listeria. It destroys bacteria, mold, spores, and viruses on up to four toothbrushes in just 10 minutes, and is a mere 3 1/2" diameter. The sanitizer activates at the touch of a button, and shuts off automatically at the end of the cycle. Removable drip cup is easy to clean, and two removable inserts are included for shorter electric toothbrush heads or children’s toothbrushes. UV bulb is rated for 2,000 hours of use. Plugs into AC. 6" H x 3 1/2" Diam. (12 oz.)
