What Smith Filter Corporation does
Smith Filter Corporation is a Moline, Illinois-based manufacturer of air and grease filtration products founded in 1939. The company's catalog spans permanent and disposable air filters, HEPA and V-Bank configurations, and branded grease filtration lines marketed as Fire Patrol, Fire Guard, and Thrifty Flame Stop. It also produces specialty filtration units for emerging applications including crypto mining facilities, data centers, and industrial processing environments. Manufacturing is in-house and includes custom build capability with a stated one-week turnaround, which is positioned as a differentiator against catalog-only competitors.
The company serves four primary end markets: commercial kitchens (driven by grease and fire-code compliance), general industrial facilities, data centers and crypto mining operations, and distributor/reseller channels. It holds NAFA Quality Control and ISO certifications, both of which are procurement gating requirements for institutional and OEM buyers. Distribution is dual-channel, combining a direct sales force with a reseller network, allowing reach into both specification-driven and replacement-cycle-driven demand.
Smith Filter operates as a privately held company with 11-50 employees. In July 2024 the company was acquired by Rensa Filtration, joining a private filtration platform that likely provides shared back-office, sourcing, and channel scale. Workforce development is supported through a partnership with Riverbend FAME. No revenue figures, unit volumes, or pricing data are disclosed in the public material available.
