Water Purification Systems Market size is estimated at USD 56.1 billion in 2024 and is projected to cross USD 115.4 billion by the end of 2037, registering more than 6.2% CAGR during the forecast period i.e., between 2025-2037. In 2025, the industry size of water purification systems is evaluated at USD 59.6 billion. Rising pollutants, contaminants, and waterborne diseases-related concerns are boosting consumers to actively seek reliable sources to ensure safe and clean drinking water access. The industry is further witnessing a technological advancement surge, leading to innovation in these systems. Advanced filtration technologies include UV purification, reverse osmosis, and activated carbon filtration.
According to a report published by WHO, in September 2023, globally, at least 1.7 billion people use a drinking water source contaminated with Microbial contamination, and consumption of this contaminated drinking water can transmit diseases such as diarrhea, cholera, dysentery, typhoid, and polio and is estimated to cause approximately 505000 diarrheal deaths each year. Accompanying the growth in the global population, safe and reliable water scarcity is affecting the healthy living of humans. Contaminated water not only causes diarrheal diseases but also causes acute respiratory infections and numerous neglected tropical diseases, recurring increment in demand for water purification systems and development in technology.

Product Type (POE-POU Systems, Filters, Purifiers, Others)
With growing awareness about the usage of safe and purified water for residential purposes, the demand for installed water purification systems is expected to reach a higher value every year. Point of Entry (POE) and Point of Use (POU) systems in water purification are now leading the water purification systems market due to their one-time installation, cost-effectiveness, and convenience. POE treatment devices are installed at the entrance of the water supply before getting distributed in the entire house and on the other hand, POU devices are dedicated to complying with an individual water supply, such as: a faucet or, sink, which can easily sit on a counter, attach to the faucet, or be installed under the sink. A research paper published by the Senate Committee on Agriculture, Nutrition & Forestry, in April 2022, stated that POU-POE Systems are being considered more efficient than the Central Water Treatment System and to be considered for being the CWS in the future.
In the last few years, several tests run by public health concerned organizations, such as: WHO, identified tap water hardness in many developing regions, including Japan. As water filters hold the ability to better both the taste and purity level, the surge for such water filters is increased. These water treatment devices are also customizable by functioning as per the condition of the water source. NSF says, that according to a survey conducted by Aquasana, in 2023, 91% of Americans use a water filter, increased by 25% since 2020, due to consumer shifts in believing that it is healthier and better for the planet.
Water purifiers are also enlisted as consumers' choice for water treatment, due to its variety and affordability, especially in rural areas, where the economic growth is lower than other developing countries. According to a 2018 published report by International Journal of Pure and Applied Mathematics, it was forecasted that the water purifier market in India would witness compounded annual growth rate of 30% till 2019, which by now expected to grow even larger by the population growth in the country. Other systems such as central water treatment systems, traditional systems, portable purifiers, etc., are also contributing in booming the water purification systems market size due to high demand of various options for water purification.
Technologies (Reverse Osmosis, Activated Carbon Filtration, Ultraviolet (UV) Purification, Distillation, Ion Exchange, Ceramic Filtration)
By technology, the UV purification system garnered a significant amount of revenue in 2024. An article published by UNICEF has reported that over 829,000 people die every year due to consumption of contaminated water. The report also estimated, that at least USD 114 billion (three times the current investment) is needed per year to avail a hygienic environment with safe drinking water for developing countries by 2030. It traces clear evidence of an increase in a surge of advanced technologies in water purification systems production and supply in the water purification systems market. UV water purification systems are hence expected to witness significant growth in both residential and commercial office or, kitchen usage.
UV technology’s effectiveness in eliminating a vast range of viruses and microorganisms, and offering a reliable method for water disinfection is boosting the segment’s growth. Following the global water scarcity, engineers and scientists are further working together to harvest new ways and technologies to enhance the ability of conventional water purification systems. these upgrades and launches should be able to assess and convert even unconventional water sources, such as seawater or, even wastewater into usable water.

North America Market Trends and Analysis
North America water purification systems market is set to account for revenue share of around 28.8% by 2037. NSF says, that according to a survey conducted by Aquasana, in 2023, 91% of Americans use a water filter, increased by 25% since 2020. Raising water scarcity, faster urbanization, and increasing demand for purified water, along with Asia being the top export destination, US water purification system exports are expected to reach USD 206.06 billion by 2037.
The U.S. water purification systems market is expected to witness remarkable growth in the upcoming years. Stringent water quality standards are one of the major reasons driving the industry to emphasize. Increased demand for advanced water filtration devices is marking a prominent change in this sector with a greater hike. Government bodies are also showing interest in building water resources from recycled water, boosting the demand for durable purification systems. In September 2023, the Department of the Interior announced an investment of USD 8.3 billion in a large-scale water infrastructure project for five years. Further including water purification and reuse, water storage and conveyance, desalination, and dam safety.
Canada is witnessing a surge in the need for safe water sources, due to intensifying floods and droughts, degraded water quality and habitat loss, and inadequate source water management. An article published by the Government of Canada, in 2023, marks a major increment in the demand for certified and quality water purifying systems. Factors such as these are driving the water purification systems market in Canada significantly, both in the urban and rural areas, with an emphasis on reverse osmosis, UV purification, and advanced filtration solutions.
APAC Market Statistics
Asia contains more than 60% of the world's total population and is a promising water and sanitation market with great potential.
