The Role of Dissolved Ozone(O3) in Nanobubble
- Virus Extermination 
Dissolved ozone(O3) in nanobubble state in sprayed water particles is attached to the surrounding virus by the adhesion of water and kills virus 100%.

Organisms are based on the combination of carbon(C) and hydrogen(H), consequentially bound to elements of oxygen(O), nitrogen(N), sulfur(S), and phosphorus(P), so that it form the backbone of one's life activities. 

The combined power of carbon and hydrogen is determined by the electronegativity, which is one of the characteristics of the atomic structure. And, the force between hydrogen and carbon elements is χ=2.55 (χ: Pauling scale) and lower than the electronegativity(χ = 3.44) of hydrogen and oxygen atoms(O). (The strength of oxygen's hydrogen bond is hundreds of times than carbon’s.) 

That is, when ozone contacts with virus, ozone in unstable binding chain is divided into oxygen molecules and oxygen atoms (O₃ → O₂ + O). Then, oxygen atoms(O) take away hydrogen atoms with strong force and changes over to stable water(H2O). The virus of hydrocarbon bonds that have been stripped of hydrogen atoms(H) is soon extinct.

Comparison of O3 Response Efficiency (Bubble Generated by Aeration Device VS Fawoo’s)

Bubbles generated by aeration devices are about 0.4㎜ in size, and those bubbles rise to the surface of the water as soon as generated and react with partial of contaminants (Max 10%) that bubbles stick to while rising.

 → ① The remaining 90% with O3 will explode and disappear from the surface after rising.② Ozone removal device is needed.

In case of Fawoo’s nanobubble, bubbles exist with size of 300㎚ or smaller in the water for a long time and are stuck around the pollutant and responding. So that, it results with various effects.

→ ① It affects quickly with just 10% of ozone amount. ② Ozone removal device is not needed.



It can be used by spraying aerosol in air as well as dissolved in water.



A. Yes, a sprayer made of stainless steel or silicon can be sprayed with nanobubble ozone water.

A. Yes, you can choose large or small generator depending on your needs wherever you have electricity for home/industrial use.

- Large Nanobubble Ozone Water Generator: 600 ton/day - Power usage 5.3 kW/h, 380V

- Small Nanobubble Ozone Water Generator: 20 ton/day - Power usage 1,250 W/h, 220V


A. Ozone usually exists in the air below 0.01 to 0.09 ppm. At these concentrations, viruses cannot be killed. In general, viruses have shells for self-protection, and in order to destroy them, they need to be in contact with ozone concentrations of 0.2 ppm or more for a certain amount of time. E. coli (O-157), salmonella and staphylococcus must be exposed to normal ozone water for at least a few seconds before sterilization can occur. The characteristics of nanobubble water (H2O) with dissolved ozone are adhesion and cohesion. While nanobubble ozone water clings to any surface where it is sprayed and stays in the form of water droplets for a few seconds, ozone sticks to the virus and has a powerful oxidation effect, which kills the virus.
