NIGP 31223: Air Filtration Equipment for Soft and Hard Shelters

NIGP 31223 Air Filtration Equipment For Soft And Hard Shelters, an Item code, covers portable and fixed air filtration systems designed for temporary and permanent shelter structures. State and local governments procure these systems primarily for emergency response, disaster relief, and facility management — including HEPA filtration units, portable air cleaners, and shelter-mounted ventilation systems that meet containment and air-quality standards for occupied structures ranging from field hospitals and evacuation centers to permanent municipal buildings. The code attracts procurement activity from state emergency management agencies, county health departments, city facilities management bureaus, and special-purpose districts managing public shelters or disaster-response infrastructure.

The source provided contains no records of recent state and local contract opportunities under this code, making it difficult to characterize current issuing-body concentration, geographic activity, or representative solicitations at this time.
