Liquid Filtration Market Report 2026

The liquid filtration market size has grown strongly in recent years. It will grow from $3.67 billion in 2025 to $3.93 billion in 2026 at a compound annual growth rate (CAGR) of 7.2%. The growth in the historic period can be attributed to urbanization-driven water demand, industrial process expansion, regulatory compliance for effluent discharge, growth in municipal treatment plants, adoption of fabric filters.

The liquid filtration market size is expected to see strong growth in the next few years. It will grow to $5.23 billion in 2030 at a compound annual growth rate (CAGR) of 7.4%. The growth in the forecast period can be attributed to increasing water scarcity, investments in wastewater recycling, demand for high-efficiency filtration, smart monitoring adoption, expansion of industrial water treatment. Major trends in the forecast period include growing demand for clean water treatment, expansion of industrial filtration applications, adoption of advanced filter media, focus on wastewater reuse, integration of automated filtration systems.

The growth of the pharmaceutical sector is expected to drive the liquid filtration market going forward. Pharmaceuticals, including drugs and medicinal products, are used for the prevention, diagnosis, and treatment of diseases and medical conditions in humans. Liquid filtration is critical in pharmaceutical manufacturing to maintain high-quality standards by removing impurities, particles, and contaminants from liquids, ensuring that final products meet required specifications. For example, in April 2025, Eurostat, the Luxembourg-based statistical office of the European Commission, reported that the value of medicinal and pharmaceutical products increased by 13.5% compared with 2023, reaching €313.4 billion. Thus, the rise of the pharmaceutical sector is propelling the liquid filtration market.

Major companies in the liquid filtration market are focusing on advanced filtration safety technologies to meet growing demand for safer, more reliable, and high-performance operations across industrial sectors. These innovations often combine mechanical safeguards with automation features, enhancing operational safety compared to conventional filtration systems that lack pressure-control protection. For instance, in April 2023, Amazon Filters, a UK-based filtration system manufacturer, launched a mechanical safety interlock for its process industry housings. The interlock includes a secure locking mechanism that prevents operators from opening filtration housings under internal pressure, significantly reducing the risk of accidental exposure to hazardous or pressurized liquids. It is designed for use in chemical, water, pharmaceutical, food and beverage, OEM, and oil and gas industries, enhancing workplace safety, minimizing operational errors, and ensuring compliance with industrial safety standards.

In December 2024, Ahlstrom, a Finland-based provider of advanced filtration materials, specialty filter media, and sustainable fiber-based solutions, acquired ErtelAlsop for an undisclosed amount. Through this acquisition, Ahlstrom aimed to strengthen its liquid-filtration portfolio, expand its presence in pharmaceutical and industrial filtration applications, and enhance its product range in depth-filter media and filtration systems. ErtelAlsop is a US-based provider of liquid-filtration solutions, offering depth-filter media, filter pads, lenticular filters, filter presses, and turnkey liquid-filtration systems for pharmaceutical, biotechnology, food and beverage, and chemical processing industries.
