InSinkErator has Introduced LEDefense
InSinkErator's LEDefense is a new sink flange technology that integrates antimicrobial LED light into garbage disposals to continuously combat odor-causing bacteria and inhibit mold growth. This innovation was developed in collaboration with the health technology company Vyv. It presents the first application of always-on visible light disinfection within the category of residential kitchen appliances.
The LEDefense system emits a specific wavelength of visible light, between 400 and 420 nanometers, which has been shown in laboratory testing to kill 99% of odor-causing bacteria while remaining completely free of ultraviolet radiation and safe for continuous, unrestricted use around people and pets. The light is described as a pleasant purplish-blue hue, and its placement in the sink flange allows it to illuminate the grind chamber and surrounding areas where bacterial growth typically thrives.
