Ozone generators are being installed in airplanes, malls, banks, public service offices, hotels, manufacturing facilities, and religious places to make them safe from the virus. With the resurgence of omicron variant, monkey pox cases globally, the demand for ozone generator is expected to boost market demand.

Factors affecting the price of ozone generators include technical specifications, quality, and coverage area. The overall cost associated with the operation and maintenance of ozone generators is high, which proves to be a deciding factor for many consumers. The high operational cost is related to the cost of electricity required for the functioning of the product. Similarly, recurring maintenance cost is associated with the replacement of electrodes and other components. The electrodes and transformer parts, which are made up of stainless steel and titanium, need to be replaced over time owing to the deposition of moisture on the surface, thereby leading to the oxidation of the material and resulting in rusting. In addition, changes in the prices of raw materials such as glass, ceramics, quartz, titanium, and polyvinylidene fluoride lead to fluctuation in prices for ozone generators. All these factors are expected to restrain market growth for ozone generators.

Technology Insights
