Ozone Generator Market Trends

Driver - Government Incentives and Emission Targets Drive Ozone Generator Deployment

The ozone generator market is experiencing significant growth, driven by the increasing demand for advanced water treatment technologies. Municipalities are actively adopting corona discharge ozone generators due to their high ozone output, enhanced efficiency, and effective removal of chemical impurities.

Governments across the world are regulating the water treatment procedures. The regulatory committees are encouraging several sectors to use the ozone disinfection method for commercial water treatment. In the U.S., the EPA regulates disinfection methods such as ozone, for unfiltered public water systems to control waterborne pathogens such as Cryptosporidium.

The market players are investing more in product development to expand their market reach. For instance, in April 2023, Fresh Mouth launched a new ozone generator that also functions as a hydrogenated water producer. This dual-function device targets oral hygiene, producing ozone to eliminate bacteria, viruses, and fungi, highlighting the versatility and safety of corona discharge in personal care applications.

Restraint - Ozone Safety Regulations Pose Challenges for Market Growth

Ozone is a powerful oxidant; although highly effective for water disinfection, it can cause respiratory irritation and lung damage at high concentrations. This property is a significant restraint for the market, especially in enclosed environments.

Regulatory agencies, including the U.S. Occupational Safety and Health Administration and the European Chemicals Agency, have established threshold values for ozone, requiring monitoring and control systems to ensure safe use. This need for controlled environments limits the broader adoption of ozone generators in residential and commercial environments, thereby restricting the overall market growth.

Opportunity - Emerging Opportunities in the Agriculture Sector to Boost Ozone Market Potential

The rising importance of sustainable and chemical-free processes in the agriculture industry is creating significant opportunities for the ozone generator market. Ozone’s strong oxidizing properties make it highly effective in sterilizing irrigation and aquaculture water. These properties eliminate harmful pathogens, promoting healthier crops without leaving toxic residues.

Governments across the emerging regions are responding with large-scale investments in the market. The strong oxidizing properties of ozone are driving its increased adoption in non-traditional applications such as soil remediation, greenhouse sanitation, and fish farming. Under the MENA Desalination Projects Forum 2022, Saudi Arabia announced an investment of approximately USD 9.33 Bn across 60 water projects, including the establishment of new wastewater treatment plants incorporating ozone technology for enhanced wastewater reuse in agriculture.

Category-wise Analysis

Technology Insights

Based on technology, corona discharge technology dominates the market in 2025, with a share of 59.7%, due to its superior efficiency, scalability, and cost effectiveness. Corona discharge systems can produce ozone concentrations of up to 22% by weight, significantly outperforming other methods that typically generate only around 3%. This high output enables corona discharge systems to treat large volumes of water at lower cost.

In Asia Pacific, rising urbanization and environmental concerns have led to stricter water and air quality regulations. For instance, India’s National Mission for Clean Ganga and China’s Five-Year Environmental Plans emphasize ozone-based disinfection to reduce chemical use and improve water quality.
