Top Active Harmonic Filter Companies

The global active harmonic filter market is projected to reach USD 1.11 billion by 2030 from an estimated USD 0.76 billion in 2025, at a CAGR of 7.8% during the forecast period. The active harmonic filter market is driven by the surging deployment of nonlinear loads such as variable-frequency drives, inverters, and IT equipment, which generate harmonic distortion and degrade power quality. Concurrently, stricter global regulations and standards on power quality and energy efficiency compel industries to adopt advanced mitigation solutions. The increasing integration of renewable energy sources and smart grid infrastructure further raises demand, as these systems introduce harmonics that require dynamic compensation, which is offered by active filters.
