UNSPSC 40161516: Inline filters

UNSPSC 40161516 Inline filters, a Commodity code, covers replacement and spare filtration components that state and local governments source for water treatment plants, municipal facilities, and school operations. Recent solicitations show concrete demand for dust-collector bags used in lime-house filtration systems, pleated air filters in multiple MERV ratings for HVAC systems serving public buildings, and specialized flow-control assemblies paired with filtration equipment at water treatment plants. Issuing bodies include municipal water utilities, city departments of public purchases, county utilities, and school districts. The work centers on sourcing OEM or equivalent replacement parts to keep existing treatment and air-handling systems operational, often with multi-year pricing locked under blanket purchase agreements or framework contracts.

Activity appears concentrated in Florida and Texas.
