Research shows that germs can remain and breed on wet toothbrushes after brushing, potentially prolonging infections such as gum disease or sore throats. And, because airborne bacteria can move from toothbrush to toothbrush (and from other sources in the bathroom), opportunistic infections, like periodontal disease and common colds/flu, can easily be passed from one person to another when unsanitized toothbrushes are stored together. The Germ Terminator Toothbrush Sanitizer provides a clean, healthy toothbrush every time you brush your teeth. The Germ Terminator is the only toothbrush sanitizer to use natural steam and dry heat to kill greater than 99.9999% of germs on your toothbrush and store it in a completely germ-free environment between brushings. The Germ Terminator works with electric and manual toothbrushes. The product is FDA-cleared (510k-clearance) and is modeled after the steam device in dental offices to sterilize instruments. It can be used worldwide with the proper plug adapter (100-240V). UL Listed, Worldwide Safety Certifications.
