NIGP 03149: Filter Frames, Metal

NIGP 03149 Filter Frames, Metal is an Item code that encompasses metal-framed HVAC air filters and related filtration components that state and local governments procure for facilities maintenance and environmental control. Recent solicitations show that jurisdictions are buying pleated panel filters (MERV 8, MERV 8-A, and MERV 14 configurations), extended surface rigid box filters for VAV systems, curb inlet filters with fabric linings for stormwater management, and ERU (Emergency Response Unit) filters. Filters must meet ASHRAE standards 52.1 and 52.2 compliance and UL 900 flammability ratings where specified. The issuing-body mix spans school districts (Cherokee County School District, Forsyth County Schools, Gwinnett County Public Schools, Fairfax County Public Schools), county governments (Boulder County, San Mateo County, Fairfax County Government), municipalities (City of Charlotte, City of Richardson, Texas), and higher-education institutions (University of Mississippi). Transit authorities also procure under this code—the City of Charlotte's CATS (Carolinas Area Transit System) facility maintenance RFP includes boiler and chiller filter components alongside related HVAC services.

Recent activity concentrates in the Southeast and Southwest, with multiple school-district and county opportunities in Georgia (Cherokee, Gwinnett, Forsyth Counties), Colorado (Boulder County), California (San Mateo County), Virginia (Fairfax County), North Carolina (Charlotte), Texas (Richardson), and Mississippi.
