This website is advertising the VirtuCLEAN CPAP cleaning device, which uses ozone to kill 99.9% of bacteria in CPAP equipment within 30 minutes without water. It claims VirtuCLEAN is an easy and hands-free way to deeply clean CPAP masks, tubes, and machines on a daily basis. The device works by generating ozone gas that creates oxidative bursts to destroy bacteria cell walls and structures, killing them without the risk of immunity building. It is recommended to clean CPAP equipment at least once a week to prevent bacterial infections and ensure efficient machine operation.
