Market Overview:
The global harmonic filter market size is expected to reach USD 2.77 billion by 2034, exhibiting a CAGR of 9.1% during 2025–2034.
A harmonic filter is an apparatus utilized to control and diminish harmonics in a power system to acceptable levels. This harmonic filter is intended to eliminate or reduce harmonic resonance and distortion at key working circuit points. Typically, high currents entering and leaving devices lead to harmonic distortion. A harmonic filter reduces operating costs and expenses while stopping very high harmonics from damaging equipment. To avoid damage to components or penalties from utility providers, these are utilized across various sectors such as HVAC, oil, gas, mining, and wastewater.
Growth Drivers and Opportunities:
- The automation of industrial processes typically includes the application of variable frequency drives (VFDs) for the control of motors and various equipment. VFDs produce harmonic distortions, requiring the inclusion of harmonic filters to ensure power quality.
- The increasing global urbanization drives the market. Renewable energy options like solar panels are commonly installed in cities, leading to the necessity for efficient filtering via harmonic filters to maintain reliable grid function and adhere to power quality standards.
