If you're looking for the best way to make ozonated water at home, you've probably noticed that ozone generators vary widely in both price and design. At first glance they may appear to do the same thing, but the technology inside them can be very different.
Many lower-cost ozone generators rely on Corona Arc technology. These systems create ozone from the surrounding air and use an air pump, tubing, and a diffuser stone to bubble the ozone through the water. While this approach has been used successfully for many years, it also releases ozone gas into the surrounding air during operation. Since ozone gas can irritate the lungs at elevated concentrations, minimizing unnecessary ozone in the air is an important consideration for indoor use.
A newer approach is electrolytic ozone technology.
Instead of generating ozone from air, electrolytic systems produce ozone directly from the water itself using only water and electricity. Because the ozone is created inside the water, significantly less ozone is released into the surrounding air during normal operation. The result is a system that is typically quieter, more compact, easier to use, and better suited for producing ozonated water in the home.
Corona Arc vs. Electrolytic Ozone Technology
Both technologies are capable of producing dissolved ozone in water when properly designed and operated. The primary difference is how the ozone is generated and delivered, which directly affects convenience, portability, maintenance requirements, and the amount of ozone that may be released into the surrounding air during use.
For many homeowners, that makes electrolytic ozone an attractive choice for everyday applications such as:
- Making questionable water safer to drink
- Washing fruits and vegetables - ozone helps break down pesticides and herbicides and produce lasts longer in the fridge
- cleaning baby teethers/bottles - ozone purifies objects but leaves no chemicals behind
- Cleaning cutting boards and kitchen sponges
- Growing microgreens - faster sprouting and growth
Roving Blue® developed EO3® electrolytic ozone technology to simplify the process of making ozonated water. Rather than relying on pumps and tubing, EO3® systems generate ozone directly from the water itself, producing fresh ozonated water in just minutes while remaining compact, quiet, and energy efficient. Whether you're looking for a countertop system for your home or a portable solution for travel and emergency preparedness, electrolytic ozone technology offers a modern alternative to traditional air-fed ozone generators.
