Replacement Spa or Pool Filter With No Part Number
A faded or missing label does not mean you are stuck. Most cartridges can be identified by measurement.
Measure the overall length, outside diameter, top and bottom end style, hole opening and any thread or spigot size, then search by those measurements.
A cartridge can match on length and diameter but still have the wrong end caps. Always check the top end, bottom end, hole opening and thread or spigot size, and confirm on the product listing before ordering.
Not sure which one? Use our Pool & Spa Filter Cartridge Finder to search by length, diameter, end-cap type, hole size and thread or spigot size.
