The FDA classifies ozone as GRAS (Generally Recognized as Safe) for food and bottled water use.
-
The EPA and Water Quality Association (WQA) both recognize ozone as a safe and effective method for water treatment. The WQA states that “ozone is the most powerful oxidizer available that can be safely used in water treatment.”
-
Ozone naturally reverts to oxygen after doing its job, leaving no chemical residues behind—unlike chlorine or iodine.
-
It’s been used in municipal systems for over 100 years and in many of the world’s top bottled water brands.
-
Ozone is approved for use in drinking water, bottled water, produce washing, and food surface sanitation.
-
It rapidly breaks down into ordinary oxygen (O₂), leaving no chemical residue behind—unlike chlorine or iodine.
-
There are no peer-reviewed studies showing that dissolved ozone at levels used for water treatment is harmful to humans, animals, or the environment.
Not only is dissolved ozone non-toxic, it’s also known for eliminating unpleasant tastes and odors, improving the overall quality of your water. When it comes to purity, ozone-treated water is one of the cleanest choices available.
