The harmonic filter market size was valued at USD 1.16 billion in 2024. The market is projected to grow from USD 1.27 billion in 2025 to USD 2.77 billion by 2034, exhibiting a CAGR of 9.1% during 2025–2034.
Harmonic filters are essential devices in electrical systems designed to reduce harmonic distortion, which adversely affects power quality and efficiency. Harmonic filters operate by providing a low-impedance path for harmonic currents, allowing them to bypass sensitive equipment and minimizing distortion in the power system.
The growing use of variable frequency drives (VFDs) is driving the global harmonic filter market. VFDs convert AC to DC and then back to AC at variable frequencies, which introduce harmonic distortions in the electrical system, leading to issues such as overheating of equipment, reduced efficiency, and increased losses. Harmonic filters help reduce these issues and expand the efficiency and lifespan of electrical systems, thereby boosting demand.
The emergence of artificial intelligence is propelling the global harmonic filter market growth. AI algorithms analyze data from electrical systems to predict when equipment might fail due to harmonic distortion. This proactive approach encourages the installation of harmonic filters to prevent issues, boosting demand.

Automation of industrial processes generally involves the use of variable frequency drives (VFDs) to control motors and other equipment. VFDs generate harmonic distortions, necessitating the installation of harmonic filters to maintain power quality. Furthermore, many automated processes rely on sensitive electronic devices and control systems that are more susceptible to power quality issues. Harmonic filters help protect these systems from the negative effects of harmonics. Therefore, the increasing automation of industrial processes propels the global harmonic filter market.
The rising urbanization globally fuels the harmonic filter market. As per a report published by the UN-Habitat, urban areas are already home to 55% of the world's population, and the percentage is expected to grow to 68% by 2050. Urban areas are increasingly adopting smart technologies for energy management, transportation, and communication. These technologies require stable power sources with minimal harmonic distortion to operate efficiently, boosting the demand for harmonic filtering systems. Moreover, renewable energy solutions such as solar panels are widely deployed in urban areas, prompting the need for effective filtering through harmonic filters to ensure stable grid operation and compliance with power quality regulations.
Based on product, the harmonic filter market is categorized into active, passive, and hybrid. The passive segment accounted for a major market share in 2024 due to its widespread application and cost-effectiveness. Passive filters, which consist of fixed components such as inductors, capacitors, and resistors, efficiently mitigate specific harmonic frequencies. Manufacturers favor passive solutions due to lower upfront costs and minimal maintenance requirements. Industries such as manufacturing, oil & gas, and commercial buildings significantly contribute to the demand, as these sectors prioritize stable power quality to avoid equipment damage and enhance operational efficiency.
The active segment is expected to grow at a robust pace in the coming years, owing to the increasing complexity of electrical systems and the need for adaptable solutions. Active filters provide real-time harmonic compensation, dynamically adjusting to varying load conditions and effectively managing a wider range of harmonic frequencies. The growing integration of advanced technologies, such as automation and renewable energy sources, drives the demand for these intelligent systems. Additionally, their ability to reduce overall energy costs by minimizing losses positions them favorably in markets focused on sustainability and efficiency.
In terms of phase, the harmonic filter market is bifurcated into three-phase and single phase. The three-phase segment held a larger market share in 2024 due to its extensive use in industrial and commercial applications. Three-phase systems provide more efficient power distribution and are ideal for driving large motors and heavy machinery. Industries such as manufacturing, mining, and energy production rely on these systems to maintain operational efficiency and minimize downtime. The stability and reliability of three-phase configurations, combined with their ability to handle higher loads without significant voltage drop, make them the preferred choice for large-scale operations. Additionally, the increasing demand for automation and advanced manufacturing technologies supports the dominance of this segment.
The single-phase segment is projected to grow at a rapid pace during the forecast period owing to its rising adoption in residential and light commercial applications, where smaller loads require efficient power management. The increase in smart homes and IoT devices drives the demand for single-phase solutions, as these systems integrate seamlessly into smaller infrastructures. Moreover, the ongoing shift toward renewable energy sources, such as solar panels and wind turbines, generally favors single-phase configurations, which further enhances their appeal in the market.
By region, the study provides the harmonic filter market insights into North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa. North America held the largest market share in 2024 due to the rapid adoption of advanced manufacturing processes and increasing investments in industrial automation. The presence of established industries, such as automotive, aerospace, and energy, significantly contributed to the demand for effective power quality solutions such as harmonic filters in the region. Additionally, regulatory frameworks promoting energy efficiency and power quality standards boosted harmonic filter market growth in the region.
The Asia Pacific harmonic filter market is expected to register a significant CAGR during the forecast period due to rapid industrialization and urbanization. Countries such as China and India play crucial roles in this anticipated growth. China, in particular, continues to lead the regional market due to its expansive manufacturing base and ongoing investments in infrastructure projects. The increasing implementation of smart technologies and renewable energy initiatives in the region drives the demand for effective power quality management solutions such as harmonic filters.
