The ozone generators market produces devices which create ozone (O?) for industrial applications and medical sterilisation, and water and air treatment purposes. These systems convert oxygen into ozone, which serves as a strong oxidising agent to eliminate bacteria and viruses and remove odours and chemical contaminants. The market expansion stems from three primary drivers: increasing environmental pollution recognition and improving healthcare standards, and requirements for clean air and water.  The efficient and environmentally friendly nature of ozone technology drives industries such as wastewater treatment and pharmaceuticals, and food processing to adopt this solution. The negative effects of chemical disinfectants have led to the rising popularity of ozone-based alternatives among consumers.

The continuous innovation of ultraviolet-based ozone generators and energy-efficient corona discharge technology enhances system performance and reduces operational costs, which expands ozone applications for multiple industrial sectors. Ozone adoption in commercial and industrial settings receives momentum because of smart ozone monitoring systems and IoT-enabled equipment. Multiple governments worldwide implement regulations which promote non-toxic disinfection techniques because they want to encourage ozone generator adoption. The switch to ozone solutions occurs because environmental regulations in Europe and Asian regions mandate it. The market expansion occurred mainly because government initiatives target pandemic sterilisation needs and sustainable water systems, particularly in municipal areas and healthcare facilities.

Technology Insights

The corona discharge segment led the ozone generators market in 2024, accounting for 38.9% market share. The method generates ozone through repeated electrical discharge of oxygen molecules at high voltage levels. Large industrial applications, including food processing, air purification, and wastewater treatment, can benefit from its scalability. The commercial and municipal user base favours corona discharge systems because they offer cost-effective solutions with durable construction and large ozone generation capacity. Design advancements in electrode materials, together with efficiency improvements in ozone production, have elevated the market leadership position of this segment. Its proven reliability, along with demonstrated success, drives worldwide adoption.

The cold plasma segment is expected to experience the fastest growth during the forecast period because it generates ozone through room temperature processes, which minimises heat generation. Cold plasma proves ideal for sensitive uses which require minimal heat exposure because it protects materials from damage and maintains effectiveness in applications, including air filtration improvements and food protection, and medical sterilisation. Cold plasma technology generates reactive oxygen species, which deliver powerful antibacterial results with minimal energy usage. The commercial and residential, and healthcare sectors embrace cold plasma technology more due to device miniaturisation and smart monitoring system integration. The global market for cold plasma is growing because of the need for chemical-free sterilisation and environmental concerns, and government support for energy-efficient technologies.

Application Insights

The wastewater treatment segment held the largest revenue share of 40.7% in the ozone generators market in 2024. The strong oxidising nature of ozone makes it an effective disinfectant and organic contaminant decomposer for both industrial and municipal wastewater treatment. The practice remains popular because it eliminates dangerous germs and viruses and chemical pollutants without any negative side effects. Companies and municipalities are implementing ozone-based treatment systems because environmental standards now require enhanced water quality standards. The implementation of ozone treatment reduces sludge quantity and odour levels, which improves overall process efficiency. The segment's growth is driven by increasing urbanisation and industrialisation since these factors generate more wastewater that requires advanced purification methods, thus maintaining ozone as a preferred treatment method.

The air treatment segment of the ozone generators market will demonstrate the fastest growth rate throughout the forecast period. The rising need for effective air disinfection methods stems from increasing indoor air quality problems because of elevated pollution and growing awareness about airborne illnesses. Ozone generators increasingly find applications in residential and commercial spaces and medical establishments for both mould remediation and odour elimination and sterilisation purposes. The sector benefits from technological advancements in ozone emission reduction that meet safety standards and regulatory requirements. Ozone-based air purification methods have gained accelerated adoption during the COVID-19 pandemic because they provide a chemical-free disinfection solution. Market growth in this application sector will continue to be driven by worldwide air quality regulations, together with rising urbanisation trends.
