NIGP 17533: Filter Paper and Membranes

NIGP 17533 Filter Paper and Membranes, Item code, covers the supply and replacement of specialized membrane and filter media products for municipal water treatment, wastewater recycling, and HVAC systems across state and local jurisdictions. Recent solicitations show state and local governments procuring reverse osmosis (RO) membrane elements, microfiltration (MF) membranes, HVAC air filters rated at Merv 8 or Merv 9 specifications, and associated spare parts and installation services. Water utilities and school districts dominate the issuing-body mix, with water recycling districts in California, county school districts in Georgia and North Carolina, and municipal water treatment facilities in Florida emerging as repeat buyers. The scope extends from high-capacity point-of-use systems serving regional water recycling plants to distributed HVAC maintenance across school campuses and facility networks.

Recent activity spans California, Florida, Georgia, and New York, with water treatment and recycling plants driving the largest procurement volumes.
