• Confirmed Compatibility: Compatible with select Pentair, Waterway, Beachcomber and Hot Spot systems using R173429, 817-2500, 3005845, 33521 or CMP 25392. Verify the original part number before ordering.
• Part Number & Media-Area Check: Replaces PRB25-IN, C-4326 and FC-2375. Some 50 sq ft cartridges share the same exterior size, but this 25 sq ft version is not performance-equivalent. Confirm the required filtration area.
• Size & Connection Verification: Measures 13-5/16 in. long x 5 in. OD with 2-1/8 in. threadless openings on both ends. Match the length, diameter, opening size and media area to your old filter.
• 3 oz/sq yd Pro Trilobal Media: Three-lobed polyester fibers help capture fine dirt and spa debris while supporting steady flow. An internal support core and evenly spaced pleats help maintain shape during filtration and rinsing.
• Routine Care & 2-Pack: Turn off power before opening the filter housing. Rinse gently between pleats and follow the spa manual for cleaning and replacement. Includes two cartridges for replacement or backup.
