Roving Blue® OZO-Pod™ - Purify Fruits and Vegetables


Ozone is lethal to e.coli and salmonella.  Even organic foods can contain these microbes.  Ozone also breaks down herbicides and pesticides on fruits and vegetables.

The OZO-Pod™ 10, 50, and 1000, The Tank-Keeper™ line of Ozone Water Generators, consist of the ozone water generator, the power cable, and if required, any necessary power supplies. These devices are designed to be used with clear tap water of unknown safety. The units are fully immersed into the water and the power is applied.
