UNSPSC 40161500: Filters

UNSPSC 40161500 Filters is a Class code that covers air filters, automotive filters, fuel filters, oil filters, and specialty filtration components supplied to state and local government fleets, transit systems, water treatment facilities, and school districts. State and local governments buy engine intake filters, transmission fluid filters, hydraulic system filters, potable water treatment filters, wastewater system filters, and replacement filter cartridges—both as stock consumables for ongoing fleet maintenance and as project-specific supplies for water infrastructure. The issuing bodies span city transportation and fleet departments, county water and wastewater authorities, school districts, state transportation agencies, and special-purpose water districts. Filter procurement is routine, fragmented across dozens of jurisdictions, and often bundled with related automotive or facility maintenance supplies.
