Electrostatic Precipitator Market Report 2026

The electrostatic precipitator market size has grown strongly in recent years. It will grow from $8.06 billion in 2025 to $8.52 billion in 2026 at a compound annual growth rate (CAGR) of 5.7%. The growth in the historic period can be attributed to industrial air pollution concerns, coal-fired power generation, cement and metal production growth, environmental regulations, urban air quality issues.

The electrostatic precipitator market size is expected to see strong growth in the next few years. It will grow to $10.41 billion in 2030 at a compound annual growth rate (CAGR) of 5.1%. The growth in the forecast period can be attributed to stricter emission standards, industrial modernization, renewable energy integration, smart pollution control systems, sustainability reporting requirements. Major trends in the forecast period include advanced emission control systems, retrofitting of existing plants, automation and monitoring integration, high-efficiency particle removal, industrial pollution compliance.

The growth in the industrialization and construction sectors is expected to drive the expansion of the electrostatic precipitator market. The industrialization sector involves the large-scale manufacturing and production of goods, often through mechanized processes. The construction sector encompasses the planning, development, and building of physical structures such as residential, commercial, and infrastructure projects. The rising demand for industrialization is fueled by global economic growth, technological advancements in automation, and the increasing consumer demand for manufactured goods. As industrial and construction activities grow, so does the need for effective environmental management, making electrostatic precipitators essential for controlling pollutants and ensuring regulatory compliance. For example, in September 2024, the United States Census Bureau reported that construction spending in July 2024 was estimated at a seasonally adjusted annual rate of $2.16 trillion, 6.7% higher than the July 2023 estimate of $2.02 trillion. During this period, spending on construction reached $1.23 trillion, 8.8% higher than the $1.13 trillion recorded in the same period in 2023. Thus, the growth in the industrialization and construction sectors is expected to drive the electrostatic precipitator market moving forward.

Major companies in the electrostatic precipitator market are focusing on technological advancements such as wet electrostatic precipitator (WESP) systems to enhance emission control in marine applications. A WESP system combines a high-voltage electrostatic field with a liquid collection medium to capture fine particulate matter and condensable pollutants from exhaust gases, providing higher collection efficiency and improved handling of high-moisture emissions compared with traditional dry ESPs. For example, in December 2025, Siempelkamp Energy & Drying Solutions GmbH, a Germany-based environmental technology company, launched the first commercial wet electrostatic precipitator for mineral wool and marine exhaust applications. The system features a modular design with integrated automation and safety controls, removes up to 95-96% of particulate matter and black carbon from exhaust gases, reduces operational downtime with easy maintenance, and can be retrofitted to existing exhaust systems, helping industries and vessels comply with stricter environmental regulations.
