Strict standards and guidelines have been implemented to curb air toxins and promote a hygienic living environment.

Growing health consciousness and awareness about impacts of poor indoor air quality have spurred demand for advanced residential purification systems. Ozone generators that work on the principle of photo-catalytic oxidation are a preferred technology. Some key attributes driving their adoption over other technologies include stronger disinfecting action, fast response time and lack of usage of filters or chemicals.

Apart from households, commercial buildings like malls, theaters and hospitals that house large public gatherings are also installing zonal ozone-based air purifiers. Hence, the residential as well as commercial sectors are expected to contribute to opportunities in the ozone generator market.

Market Challenge - Limited Ozone Half-life Requiring On-site Generation

One of the key challenges faced by the ozone generator market is the limited half-life of ozone, which requires on-site generation of ozone. Ozone is an unstable gas that decomposes rapidly, with a half-life of only around 20-30 minutes. This short window necessitates generation of ozone near its point of application. Transportation of ozone over long distances is not feasible due to losses during transit.

As a result, companies distributing ozone generators need to ensure local production facilities as well as a strong distribution network to provide timely deliveries to customers located across a region. Setting up multiple local production units and maintaining an efficient supply chain network entails sizable infrastructure investments.

It also leads to higher operational costs associated with managing inventories and logistics across multiple locations. Further, any disruption in the supply chain can impact timely deliveries and satisfy customer needs, thereby affecting brand image and revenues.
