String Wound Filter Materials Market Report 2026

The string wound filter materials market size has grown strongly in recent years. It will grow from $1.96 billion in 2025 to $2.12 billion in 2026 at a compound annual growth rate (CAGR) of 8.3%. The growth in the historic period can be attributed to expansion of industrial water treatment facilities, rising chemical processing activities, increasing demand for cartridge filtration systems, growth of oil and gas processing operations, availability of low-cost polymer yarns.

The string wound filter materials market size is expected to see strong growth in the next few years. It will grow to $2.87 billion in 2030 at a compound annual growth rate (CAGR) of 7.8%. The growth in the forecast period can be attributed to increasing investments in wastewater reuse, rising demand for high-purity filtration in pharmaceuticals, expansion of food and beverage processing capacity, growing adoption of sustainable filtration materials, increasing focus on long-life filter cartridges. Major trends in the forecast period include increasing adoption of depth filtration solutions, rising demand for high-chemical-resistance yarn filters, growing use in industrial water treatment, expansion of multi-layer wound density designs, enhanced focus on cost-effective filtration media.

The increasing need for wastewater treatment is expected to drive the growth of the string wound filter materials market in the forecast period. Wastewater treatment involves removing pollutants from wastewater or sewage and converting it into effluent that can be safely reintroduced into the water supply with minimal environmental impact. String wound filter materials are widely used and highly effective in this process, as they act as depth filters that trap dirt both on the surface and throughout the filter core. For example, in May 2024, An Phriomh-Oifig Staidrimh, an Ireland-based government organization, reported that domestic wastewater treatment registrations rose from 486,904 in 2022 to 492,359 in 2023, reflecting an increase of 5,455 registrations. Therefore, the growing need for wastewater treatment is boosting the string wound filter materials market.

The rising demand for clean drinking water is also expected to propel the string wound filter materials market. Clean water refers to water free from contaminants, pollutants, harmful bacteria, and pathogens, making it safe for human consumption. String wound filter materials are used to remove impurities and particulates, ensuring water safety. For instance, in January 2025, UN-Water, a Switzerland-based interagency coordination mechanism, reported that despite escalating global water challenges, 2.2 billion people lacked safely managed drinking water in 2023, including 115 million reliant on surface water, while roughly 1,000 children under age five died each day due to unsafe water. Therefore, the growing need for clean drinking water is driving the string wound filter materials market.

Major companies in the string wound filter materials market are developing high-quality and durable components, such as cartridge filter housings, to address the industry's demand for efficient filtration solutions. Cartridge filter housings serve as enclosures that securely hold filter cartridges, allowing liquids or gases to flow through the filter media to remove contaminants. For example, in May 2023, Yonseng Filter, a manufacturing company based in China, introduced cartridge filter housings, which are vital components in various filtration systems. These housings are designed to securely hold filter cartridges while enabling fluid flow through the filter media. They can be constructed from materials like stainless steel or polypropylene, ensuring durability and corrosion resistance. Cartridge filter housings are utilized in numerous applications, including water treatment, industrial processes, and pharmaceuticals, where it is essential to maintain clean and contaminant-free fluids. Additionally, these housings often feature components such as pressure gauges, drain ports, and easy access for cartridge replacement, enhancing their functionality and efficiency in supporting filtration systems.
