UNSPSC 40161508: Bag filters

UNSPSC 40161508 Bag filters, a Commodity code, covers replacement filtration media and component parts for municipal water and wastewater treatment systems—specifically filter cartridges, membrane elements, and related hardware that state and local water utilities deploy in ongoing operations and capital projects. Recent solicitations show state and local governments buying bag and cartridge filters for potable and recycled water systems, reverse osmosis membranes, microfiltration membranes, sand filters, and associated spare parts and controls for treatment plants and distribution infrastructure.

State departments, municipal water districts, county water authorities, and city public works departments drive activity under this code. West Basin Municipal Water District in California, Charlotte Water in North Carolina, the City of Tampa on behalf of Hillsborough County in Florida, the Illinois Secretary of State, and the City of LaGrange in Georgia have posted recent opportunities. Geographic concentration is heaviest in California, Florida, North Carolina, Georgia, and Texas, with secondary activity in Illinois, Connecticut, Wisconsin, and New Mexico. Representative recent opportunities include West Basin's RFQ for 852 reverse osmosis membrane elements and spare parts for the Juanita Millender-McDonald Carson Regional Water Recycling Plant (due February 26, 2026); Charlotte Water's ITB for a complete pressurized strainer-type filter system with dual 10-micron and 5-micron screen cartridges for the Mallard Creek Water Resource Recovery Facility (due May 27, 2026); and the City of Tampa's RFQ for 600 units of 50-micron and 1,020 units of 20-micron polypropylene filter cartridges (due February 19, 2026). Most recent awards specify firm pricing, delivery within 60 days or less, NSF 60/61 or equivalent certifications, and multi-year supply or framework agreements with optional renewals.
