Our patented KSUV-18 Sterilizer Cabinet has been proven to provide superior sterilization for knives and other kitchen utensils compared to other methods or similar products that use magnetic bars or metal racks to secure those items. Our exclusive non-filtering clear slotted knife holding rack and special mirrored interior walls eliminate any shadows on knife surfaces within the cabinet and force the powerful UV-C light to bounce and reach every surface, providing complete sterilization. The easy to operate mechanical timer can be set for up to 15 minutes, indicating when sterilization is in process, but the KSUV-18 will safely sterilize your utensils in under 4 minutes with 99% efficacy.** It’s like a SPF-99 (Sterilization Protection Factor) for your knives. Now, with the emergence of the corona virus, customers tell us they are also re-purposing the power of the UV-C light in an attempt to sterilize masks for re-use. While Ultraviolet Germicidal Irradiation has shown excellent results in tests on other, “similar” viruses, the CDC has not yet provided data on UV tests of COVID-19, and Edlund company cannot guarantee its effect for this purpose. However, we are hopeful their testing will indicate similar success.
