I saw on TV a device that oxygen in water to clean food.What is this device and does oxygen stay in the water?

Answer 1

I just did a quick google search and I found two different types of products.

One claims to be able to create something they call Super Oxygenated water  and claim that it can contain oxygen up to be 24% by volume, or 240,000 ppm (parts per million). Normal water contains just a few ppm of oxygen. This product is phony. What they claim is impossible. The product will not work and I would never consider buying one. The first link to one of the Super Oxygenated water products.

The other type of product uses a special type of oxygen called ozone. Ozone is a poison that can kill bacteria and other microbes. It is fairly safe to use because it degrades rapidly into just regular oxygen. There are systems to disinfect hot tubs and swimming pools that use ozone. It is all so used for other disinfection tasks. This product does work and is safe to use, but it appears to be only suitable for industrial use such as cleaning produce for farms and vegetable packers. (see the second link)
