Larger 4.5″ diameter than standard 2.5″ cartridges
High-quality cartridge filter with high particulate retention capabilities over an extended life, all at an economical price.
Thermally bonded – Manufactured through an exclusive process that thermally bonds 100% pure polypropylene microfibers with lower density at the outside surface and progressively higher density toward the center.
Ideal replacement cartridge for many of the “in-line” (Big Blue) filter housings on the market
