Atmus Filtration Technologies has taken a major step toward strengthening its position in the global filtration industry with the announcement that it will acquire Koch Filter Corporation for $450 million in cash. The deal, revealed on November 24, 2025, underscores Atmus’ strategy to diversify and expand into high-growth industrial air filtration markets, particularly in commercial and industrial HVAC, data centers, and power generation.
The acquisition gives Atmus an established and respected player in the air filtration sector. Koch Filter, founded in 1966 and headquartered in Louisville, Kentucky, has built a reputation for producing mission-critical filtration products that help improve air quality and protect equipment across a range of environments. Its portfolio includes HVAC filters, HEPA systems, activated carbon products, and specialized filtration solutions widely used across commercial buildings, manufacturing sites, health environments, and data centers.
In fiscal year 2025, Koch Filter generated $156 million in revenue, reflecting strong and consistent demand driven by increasing attention to indoor air quality, regulatory standards, and the growing need for clean environments in data-centric industries. Atmus views this expansion as an opportunity to accelerate growth while leveraging its existing global footprint and advanced media design capabilities.
According to Atmus CEO Steph Disher, the acquisition aligns perfectly with the company’s long-term strategy. “The acquisition of Koch Filter will accelerate Atmus’ growth by expanding into the industrial air filtration market,” she said. “The Koch Filter team brings deep customer relationships, extensive industry experience, and a leading product portfolio. Combined with our innovation capabilities, this positions us to unlock new opportunities.”
Financially, the transaction is expected to deliver meaningful returns. Atmus anticipates the acquisition will be accretive to Adjusted EPS and Adjusted EBITDA margin beginning in 2026. The company also projects a high-single-digit return on invested capital (ROIC) by 2028. After factoring in expected tax benefits, the present value of the deal falls to an estimated $395 million, lowering the effective purchase multiple to 10.9x after synergies and tax considerations.
To fund the acquisition, Atmus will use both existing cash reserves and borrowings under its credit facility, with the possibility of upsizing the facility to further support the transaction. The deal is expected to close in the first quarter of 2026, pending customary regulatory approvals and closing conditions.
For Atmus, this acquisition supports a broader vision: expanding beyond traditional transportation filtration into industrial, commercial, and infrastructure-based markets—sectors that are experiencing rapid transformation due to energy transition, digitalization, and heightened air quality standards. With a global presence spanning six continents and more than 4,500 employees, Atmus continues to position itself as a leader in filtration and media technology.
Once integrated, Koch Filter’s product offerings and long-standing customer base are expected to significantly enhance Atmus’ industrial platform, enabling the company to deepen its reach into sectors with growing demand for high-performance air filtration
