North American Filtration

What North American Filtration does

North American Filtration (NAF) is a private holding company headquartered in Ramsey, New Jersey that designs and manufactures water and wastewater filtration and separation systems for municipal, industrial, commercial, and aquatics end markets. The company operates through seven wholly-owned subsidiary brands — LEEM Filtration, Durco Filters (Durco Engineered Systems), Sanborn Technologies, Mass Transfer Systems (MTS), Treatment Specialties, Chemtrac LLC, and Mer-made Filter (formerly Filtrex) — each addressing specialized niches such as standardized filter leaves, fully engineered pressure leaf filters and filter presses, regenerative media filtration (RMF) for pools and water parks, ORP-based chemical controllers, and mass transfer / jet technologies.

The technical portfolio is anchored by three proprietary technology families. Regenerative Media Filtration (RMF) is a patented flex-tube system originally developed in 1923 by PER Corporation and NSF Standard 9-listed since 1964, marketed to dry cleaning, aquatics, and industrial customers. LEEM's patented filter leaf cleaning process removes fouling from filter leaves without damaging mesh, with each leaf tested for lifetime prediction. HCF (High-Capacity Feed) Sanitation is an internally developed feeder sizing and controller parameter specification that addresses disinfection byproduct formation in aquatic facilities. Durco Engineered Systems extends the platform into turnkey engineered packages that combine vessels, pumps, piping, valves, instrumentation, and controls. Manufacturing and service operations run across seven U.S. facilities in New Jersey, New York, Massachusetts, Florida, Georgia, South Carolina, and Louisiana.

NAF generates revenue primarily through three streams: capital equipment sales of filtration and separation hardware; recurring aftermarket parts, rescreens, filter media, and patented filter leaf cleaning services tied to the installed base; and engineering and technical services supporting system design, water quality assessment, and controller programming. The go-to-market is sales-led, combining enterprise field sales (with a Sales Director and field representatives targeting municipal, industrial, and aquatics accounts) and inside sales at Ramsey headquarters, with quotations, order management, and fulfillment handled through HubSpot CRM and Infor ERP. Pricing is per-project and not publicly disclosed. The company has no public funding rounds disclosed, is privately held, and has pursued growth primarily through acquisitions — Filtrex in 2023 and Durco Filters in January 2025 — under a stated strategy of water-centric consolidation.
