Truelink Capital Completes Significant Sale of Koch Filter Corporation
On November 24, 2025, Truelink Capital, a private equity firm based in Los Angeles, announced a definitive agreement to transfer ownership of Koch Filter Corporation, a prominent player in the air filtration sector, to Atmus Filtration Technologies for $450 million in cash. The deal is currently projected to close in the first quarter of 2026, pending the usual closing conditions.
Company Backgrounds
Founded in 1966, Koch Filter is well-regarded for designing and manufacturing air filtration products applicable across various commercial markets. The company’s offerings include a robust range of products such as pleated filters, high-efficiency filters, and HEPA filters, which are utilized in numerous applications. With its manufacturing roots deeply embedded in locations like Louisville, KY, East Greenville, PA, Houston, TX, and Mira Loma, CA, Koch Filter distinguishes itself as one of the few nationwide independent platforms in the air filtration landscape.
Truelink aims to leverage this sale to foster further strategic growth, ensuring that Koch Filter aligns with Atmus' commitment to innovation and operational excellence. This partnership is anticipated to provide Koch Filter's team with the necessary resources and opportunities to prosper while continuing to serve its customers and partners effectively.
Strategic Importance of the Deal
Todd Golditch, Co-Founder and Managing Partner of Truelink, emphasized the significance of this transaction, stating, "This sale not only reflects the strength of our investment strategy but also aligns with our vision for Air Distribution Technologies, Inc. (ADTi) to refine its focus on engineered air distribution solutions. Furthermore, partnering Koch Filter with Atmus is expected to unleash its potential and maximize strategic growth."
Mark Mattingly, the current CEO of Koch Filter, shared his enthusiasm regarding the partnership with Truelink and recognized the progress made by the team over the past year. He stated, “Through recent investments, we are positioned to accelerate growth in delivering innovative filtration solutions. Joining Atmus signifies an exciting new phase for our business and stakeholders.”

Doug Schuster, CEO of ADTi, also commented on the transaction, noting that it marks an important pivot for the company. He expressed gratitude for the opportunity to work with Koch Filter’s management team and stated the company's commitment to focusing its energies on enhancing efficiencies and growth through its key business units—which encompass Air Control Solutions, Air Movement Solutions, and Air Distribution Solutions.
