NIGP 49034: Filters, Optical: IR Interference, etc.

NIGP 49034 Filters, Optical: IR Interference, Etc., an Item code, encompasses heating, ventilation, and air-conditioning (HVAC) air filters and related filtration products that state and local governments procure for facilities maintenance and operations. The City of Bridgeport Department of Public Purchases and the County of Santa Clara represent the kinds of jurisdictions—municipal governments and county health departments—that solicit under this code. Bridgeport's recent bid for air filters covering product lines such as AEROPLEAT IV, GEOPLEAT, AEROPAC, and AIRFLOW PLEAT M10 with varying ASHRAE MERV ratings and thickness specifications illustrates the commodity focus: consumable filtration supplies meeting specific performance and manufacturing standards (UL Class 900 listing, ISO 9001:2000 certification, ASHRAE Standard 52.2-2007 compliance) for routine replacement across schools and municipal facilities. The County of Santa Clara's concurrent ITB for ophthalmic instruments, services, supplies, and accessories, while broader in scope than air filtration, underscores diversity in how state and local procurement offices classify optical and filtering products within this taxonomy.

Recent activity concentrates in Connecticut and California. The City of Bridgeport solicited air filters (ITB BMB005277) with electronic bids due July 23, 2026, under a firm fixed-price contract structure extending through 2029 with an optional two-year extension, covering five filter product lines and requiring delivery pricing to individual schools and departments with no freight or fuel surcharges. The County of Santa Clara issued an all-or-none ITB (ITB-PRC-FY26-0664) for ophthalmic instruments, supplies, and accessories with bids due July 10, 2026, on a three-year contract term requiring bidders to serve as qualified distributors, manufacturers, or authorized service providers and to supply evaluation units for validation. Both solicitations emphasize firm pricing, manufacturing certifications, and multi-year commitment structures typical of state and local procurement cycles.
