# Antimicrobial Sink Flange Technologies InSinkErator has Introduced LEDefense By Kalin Ned | Published 2026-03-06 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/sink-flange References: [vyv.tech](https://vyv.tech/press-releases/insinkerator-launches-ledefense-powered-by-vyvs-patented-405nm-antimicrobial-light-technology/)  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](https://www.trendhunter.com/trends/spectrum-blue-antimicrobial). This innovation was developed in collaboration with the health technology company [Vyv](https://www.trendhunter.com/trends/vyv). It presents the first application of always-on visible light disinfection within the category of [residential kitchen appliances](https://www.trendhunter.com/trends/luxury-kitchen-sink). 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.
