Water Purifier Market Size

The global water purifier market size was valued at USD 48.1 billion in 2025. The market is expected to grow from USD 50.8 billion in 2026 to USD 97 billion in 2035, at a CAGR of 7.5%, according to latest report published by Global Market Insights Inc.

The fast-growing market is primarily being driven by the increasing incidence of waterborne disease. In India alone, approximately 37.7 million people experience a waterborne illness every year, and 1.5 million children will lose their lives to diarrhea due to contaminated water. The presence of a water purifier is essential in order to provide safe drinking water for all people and alleviate the health risk associated with drinking contaminated water.
 

Another driver behind the water purification market is the contamination of industrial wastewater. The United Nations estimates that approximately 80% of all the wastewater generated globally is discharged without any treatment, In the U.S., outdated systems are still responsible for over 850 billion gallons of untreated wastewater being released each year by the approximately 34 billion gallons of wastewater treated every day by EPA regulated facilities. The need for advanced water treatment systems is evident.

Further, as the overall disposable income of consumers increase, more consumers will be able to afford to purchase water purification products. As the middle-class population in developing countries continues to grow, the demand for cost-effective and efficient methods of purifying drinking water will also increase significantly. As urbanization continues to grow, the demand for reliable drinking water treatments will increase.
 

Companies like Kent RO Systems and A.O. Smith Corporation have seen the potential in these evolving patterns and designed new products to fulfill their customers' requirements. Kent provides a complete line of Reverse Osmosis (RO) and Ultraviolet (UV) purification systems while A.O. Smith manufactures many advanced water filtration options for its clients.

• Offline channel segment of the market is dominating the market at present, mainly because there are many people that prefer to see their products in person rather than rely on digital channels, in addition, as water purifiers are viewed as a long-term investment, most purchasers want to see before buying, therefore making them feel more secure about making a purchase based on their evaluation of the quality & performance of the water purifier.
   
• According to data from the Ministry of Consumer Affairs, offline sales accounted for approximately 67% of the market in India as of 2023. The growth of offline purchases can be attributed to the fact that many areas particularly in rural and semi-urban areas have a lower rate of internet usage than urban areas.
   
• In addition, many online retailers' ecommerce models are dependent on having consumers being able to take advantage of the large number of professional installation services that are provided by offline sellers, therefore leading to a significant difference in the level of sales for offline sellers than for online sellers.
   
• Major water purifier brands, including Kent RO Systems and Eureka Forbes, have capitalized on the trend towards offline purchasing by expanding their offline distribution networks. Kent RO currently operates over 1500 retail outlets in India and has therefore made itself available to consumers throughout both Urban and Rural India. Similarly, Eureka Forbes has strengthened its offline presence by establishing Exclusive Brand Stores and also by partnering with Multi Brand Retailers in order to ensure their customers receive a Seamless Shopping Experience.
   
• The online segment has experienced tremendous growth with the increase of eCommerce; however, the offline channel continues to be an important avenue for a large number of consumers. This is due to the offline channel’s ability to deliver personalized service and real-time assistance, while also providing a physical shopping experience. With limited digital infrastructure in some areas, the offline channel will continue to play a critical role in the water purification market..
