NIGP 03143: Filter Coating, Adhesive, Coil Cleaners, Degreasing Solvents, etc.

NIGP 03143 Filter Coating, Adhesive, Coil Cleaners, Degreasing Solvents, Etc., an Item code, encompasses HVAC air filters and related maintenance supplies that state and local governments procure for facilities operations across school districts, county governments, and transit authorities. Recent solicitations show purchasing focused on replacement and preventative maintenance of HVAC filtration systems across multi-building portfolios. The City of Charlotte's Transit Authority (CATS) and county school districts represent the primary issuing-body types, though county government operations also participate. Jurisdictions typically solicit filters and related services on as-needed or term-contract bases to support building operations, often bundling air-filter procurement with broader HVAC maintenance and repair scoping.

Activity over the past four months concentrates in the Southeast, with three of four substantive opportunities posted by Georgia and North Carolina jurisdictions. Gwinnett County Public Schools (Georgia) issued a competitive sealed bid for HVAC air filter replacement services due September 16, 2026 (Solicitation PE77021NONST2027000000204). Fairfax County Public Schools and Fairfax County Government (Virginia) posted an RFP establishing a term contract for HVAC air filters on an as-needed basis across all departments, due August 28, 2026 (Solicitation 2000004409). The City of Charlotte posted a preventative maintenance and repair RFP for boiler and chiller systems at CATS facilities due October 15, 2026 (Solicitation 26920271769), which includes filter and coil cleaning services within the broader scope of equipment optimization and maintenance. A cooperative purchasing vehicle through Sourcewell (State of Minnesota) solicited law enforcement equipment in May 2026, representing broader multi-jurisdictional activity but offering less direct relevance to the core filter and degreaser market.
