Water Hardness Test Strip Market Report 2026

The water hardness test strip market size has grown steadily in recent years. It will grow from $64.01 billion in 2025 to $66.29 billion in 2026 at a compound annual growth rate (CAGR) of 3.6%. The growth in the historic period can be attributed to increasing awareness of water quality issues, expansion of industrial water treatment processes, growth of laboratory testing practices, rising household water treatment adoption, availability of low-cost diagnostic strips.

The water hardness test strip market size is expected to see steady growth in the next few years. It will grow to $76.06 billion in 2030 at a compound annual growth rate (CAGR) of 3.5%. The growth in the forecast period can be attributed to increasing demand for decentralized water testing, rising adoption in smart water systems, expansion of industrial compliance monitoring, growing consumer awareness of water hardness impacts, increasing use in routine water analysis. Major trends in the forecast period include increasing use of rapid water quality testing tools, rising demand for on-site hardness monitoring, growing adoption in industrial water treatment, expansion of consumer-level testing solutions, enhanced focus on accurate mineral detection.

The increasing demand for water softening solutions is expected to drive growth in the water hardness test strip market going forward. Water softening solutions are designed to lower the concentration of minerals - primarily calcium and magnesium ions - in water, addressing issues such as scale buildup, appliance damage, and reduced soap effectiveness. Water hardness test strips support this demand by providing consumers with an easy and accurate way to measure mineral content, enabling informed decisions about the use of appropriate water treatment solutions. For instance, in January 2024, the U.S. Geological Survey, a US-based scientific agency, reported that the total value of domestic soda ash (sodium carbonate) produced in 2023 was approximately $1.9 billion, highlighting the significant use of water treatment chemicals. Therefore, the rising demand for water softening solutions is expected to propel the water hardness test strip market.

The increasing demand for clean, treated water is projected to drive the growth of the water hardness test strip market moving forward. Clean water is defined as water that is safe for drinking and domestic use, devoid of harmful contaminants and pathogens, while treated water refers to water that has undergone various purification processes, such as filtration and disinfection, to eliminate impurities and make it suitable for consumption or other uses, depending on the level of treatment applied. The rising demand for clean, treated water is attributed to concerns regarding safety, population growth, climate change, pollution, health requirements, and economic development. This increased demand for clean, treated water is likely to enhance the water hardness test strip market due to heightened consumer awareness, regulatory compliance, industrial requirements, and improved retail availability. For instance, in April 2023, a report published by the Department for Environment, Food and Rural Affairs (Defra), a UK-based government agency, indicated that water companies supply approximately 14 billion liters of water daily for public use, with households averaging 144 liters per person each day. However, due to rising demands, an additional 4 billion liters of water per day will be needed in England by 2050. Therefore, the increase in demand for clean, treated water will drive the growth of the water hardness test strip market.

Key players in the water hardness testing market are increasingly focusing on the development of industrial test kits to secure a competitive advantage. Industrial use test kits are specialized testing instruments designed for a range of industrial applications to evaluate specific parameters or qualities. For example, in August 2023, Tintometer GmbH, a Germany-based water testing company, introduced Lovibond test kits tailored specifically for industrial applications. These test kits are customized for both user and application needs, specifically adapted to various industrial processes. The Lovibond test kits are packaged in compact and durable cases, making them suitable for mobile use as 'mini-labs' directly on-site. A key benefit is that all devices, reagents, and accessories are sourced from a single provider, simplifying the management of additional supplies or supplements as necessary.
