About NIGP 27135
NIGP 27135 Filter Sets And In-Line Filters, an Item code, encompasses replacement filter assemblies and components that state and local governments procure for water treatment plants, public facilities, and school HVAC systems. Recent solicitations show state and local agencies buying dust-collector bags for lime-softening filtration, pleated air filters in various thicknesses and MERV ratings for facility-wide distribution, and specialized flow-control equipment paired with filtration components for potable water systems. The issuing bodies span cities (Tampa, Bridgeport, Lubbock), county utilities (Pinellas County Utilities), and municipal school districts (Bridgeport Public Schools), indicating activity across water and facility departments with school systems as significant end-users.

Contract terms commonly run multi-year with firm pricing through renewal periods, and delivery is typically FOB destination with all freight included in quoted prices.
