Countertop fresh fruit and vegetable preservation device

This countertop device helps keep fruits and vegetables fresh by placing them in a container where an internal generator produces ozone gas. The ozone flows over the food to kill fungus or bacteria, extending its shelf life. The claims specifically define this device as using ozone for preservation.

Why it matters: Since 2006, advancements in compact ozone generators and affordable sensor technology could make managing ozone safety and containment more feasible. This addresses the inherent challenge of using ozone in a home environment.
