UNSPSC 41104926: Silica bed filter

UNSPSC 41104926 Silica bed filter is a Commodity code covering specialized filtration media and components that state and local governments procure for water treatment, aquaculture support, and equipment-maintenance applications. The code captures silica-based filtration products used in operational systems where water clarity, particle removal, or breathing-air quality is critical. State and local issuing bodies soliciting under this code include county fire and rescue departments and state environmental or aquaculture agencies, reflecting the breadth of filtration needs across emergency response and resource-management functions.

Recent activity shows two distinct solicitation patterns. Fulton County, Georgia posted an IFB due July 28, 2026 (PE66062NONST2027000000447) for fire and rescue tools, equipment, and self-contained breathing apparatus maintenance, which includes filtration-system support and breathing air components within its Group VI scope of SCBA maintenance services, inspections, and air-system integrity. The State of Mississippi posted an IFB due May 29, 2026 (9280-26-R-IFBD-00047) seeking filtration components and associated items for an Oyster Hatchery and Research Center, a direct procurement of filtration media for aquaculture operations. These two opportunities illustrate the code's application across emergency-services infrastructure and specialized research-facility operations, with activity concentrated in the Southeast and reflecting both operational maintenance contracts and dedicated-facility procurement.
