"It uses electrolysis"

https://en.wikipedia.org/wiki/Electrolysis_of_water

The device applies an electric current to decompose water into hydrogen and oxygen gas. From what I know this gassy water does not disinfect anything.

However if you mix tap water and salt (sodium chloride) and use this device, it produces a combination of hypochlorous acid and sodium hydroxide. I would not eat anything soaked in that solution.

In conclusion, the device is neat but is either not useful or surprisingly harmful in its application.

Thanks for checking Felix. I use a plastic bowl that spins to clean salad parts. This new way looks interesting (see link below).

I saw research that says not to buy salads in plastic bags. it's more convenient but filled with bacteria. Surprisingly the bags say the salads are pre-washed. However, based on the research, you need to wash them more than if they were not in plastic bags!
