Key benefits at a glance

• Perfect fit for Jacuzzi J-200 series and RDC-50S systems, promoting consistent filtration and flow.
• Verified cross-compatibility with OEM and third-party brands (Pleatco PRB50-IN, Unicel C-4950, Filbur FC-2390) for easy swaps.
• Precise dimensions and a threadless, open-ended design: 13-5/16 in L, 5 in OD, 2-1/8 in open ends.

Advanced filtration for real-life spa use

• Pro Series 3 oz media uses triangular Trilobal fibers with Dirt-Locking technology to capture fine debris down to 10 microns.
• Non-clumping center core plus chlorine-resistant end caps resist cracking and maintain shape under pressure.
• Rigid construction supports a durable service life, with an easy rinsing process that helps prevent pleat collapse (12–24 months per set).

For everyday spa sessions, this 2-pack offers a practical, drop-in filtration upgrade that aligns with OEM standards. While results can vary with usage and water conditions, many users notice improved clarity and consistent flow during filtration cycles. Important care note: do not backwash; rinse only to preserve the integrity of the media and the seal.
