Ozone Generator Market Growth & Trends

The global ozone generator market size is expected to reach USD 2,406.0 million by 2033, expanding at a CAGR of 7.0% from 2025 to 2033, according to a new report by Grand View Research, Inc. Rising investments in up-gradation and expansion of wastewater treatment facilities are expected to boost the product demand over the coming years.

Prolonged exposure of ozone can cause lung, throat, nose, and eye irritation; shortness of breath; can adversely affect indoor plants, can damage materials including fabrics, electrical wire coating, and rubber; and can exacerbate chronic respiratory diseases, such as asthma. All these factors are expected to restrict market growth over the coming years.

The demand for ozone generators in the residential segment is anticipated to witness the highest growth. Ozone can reach every corner of the environment, unlike ultraviolet sterilization, which leaves some places unsterilized. It also leaves no poisonous residue and can be produced by simple equipment, which can be used for public transportation modes, such as high-speed railways, airplanes, ships and buses; single rooms; and large public places.
