Micro-One, a South Korean air quality management company, announced on January 13 that it has successfully raised $5.1 million (KRW 6.7 billion) in Pre-IPO funding.

The investment round included participation from Kolon Investment, IBK Venture Investment, Korea Development Bank (KDB), and Prodigy Investment. With this funding, Micro-One aims to increase the proportion of institutional investors in its shareholder base and establish a strong foundation to lead the global environmental sector.

Micro-One specializes in high-performance dust filters, incinerator manufacturing and installation, and environmental equipment. Its key products include the “PTFE (Polytetrafluoroethylene) Membrane,” a high-performance filter that removes nitrogen oxides (NOx) from exhaust gases, the “Low-Temperature SCR (Selective Catalytic Reduction)” system for effective NOx reduction at lower temperatures, and the “De-NOx Catalytic Filter,” which incorporates SCR catalysts to enhance baghouse filter functionality. The company also offers “Tripper Room” technology, designed to reduce workplace hazards by removing airborne particulate matter.

The company is actively expanding its operations across six key industries: incineration, power generation, pulp and paper, petrochemicals, cement, and steel. It has set ambitious targets of $60.8 million (KRW 80 billion) in revenue and $3.8 million (KRW 5 billion) in operating profit by 2025, striving for sustainable growth and innovation.

To achieve these goals, Micro-One plans to strengthen strategic investments across its business divisions and enhance its competitiveness in both domestic and international markets. The company is also preparing for an IPO on the KOSDAQ by 2026 as part of its long-term growth strategy.

Jun Hyuk-soo, CEO of Micro-One, stated, “This funding is a clear acknowledgment of our technological capabilities and growth potential, marking a critical milestone on our journey toward a KOSDAQ listing.” He added, “The funds will be used to enhance our R&D capabilities, expand production facilities, and build a solid foundation for global market entry.” Jun further emphasized, “Through continuous innovation and growth, we aim to deliver greater value to our investors and customers.”
