Additionally, the post-pandemic emphasis on indoor air hygiene has further accelerated this trend, making ozone generators a vital component in public health and urban planning strategies.
   
• Furthermore, ongoing partnerships among the key players will create lucrative prospects for the product growth. For instance, in April 2022, Toshiba Infrastructure Systems & Solutions Corporation (TISS) partnered with Larsen & Toubro (L&T) to supply three high-capacity ozone generators for the Chandrawal Water Treatment Plant in Delhi, India. Each unit will deliver 31 kg/hour of ozone, forming one of the largest ozonation systems in the country.
   
• The expanding food and beverage industry in the Asia Pacific is driving demand for ozone generators due to their effectiveness in sterilization and preservation. Ozone is used for sanitizing equipment, packaging, and water used in processing, ensuring compliance with hygiene standards without chemical residues. Countries including Thailand, Vietnam, and Malaysia are seeing increased adoption of ozone systems in seafood, dairy, and beverage production. The ability of ozone to extend shelf life and reduce microbial contamination makes it a valuable tool in maintaining product quality and safety.
   
• Ongoing innovations in ozone generation technology, such as energy-efficient corona discharge systems and smart control interfaces, are making ozone generators more accessible and cost-effective. Manufacturers in Japan, China, and India are offering compact, modular systems suitable for diverse applications. These advancements are reducing operational costs and improving reliability, encouraging adoption in small and medium enterprises.
