Swimara 2-Pack 78161 PWK35B C-6350 Replacement Spa Filter for Hot Spring Limelight (2018+), 14 x 6-3/8 in

Upgrade Your Limelight Filtration with Swimara 2-Pack 78161

Refresh and simplify spa maintenance with Swimara’s 2-Pack 78161 replacement filters, designed for Hot Spring Limelight series from 2018 onward. This complete dual-filter set is precision-engineered to support the Limelight’s dual-filtration system, helping sustain clear water and steady pump performance. It works across multiple models in the Limelight family, including Pulse, Flair, Flash, Beam, and Prism, giving you a practical, ready-to-install filtration upgrade that respects OEM standards.

Why this set stands out

• Complete 2-Filter System Set: A paired replacement for dual-filtration configurations, enabling a full system refresh in one purchase.
• Verified OEM & Cross-Compatibility: Cross-compatible with Pleatco PWK35B, Unicel C-6350, Filbur FC-3921, and Darlly 67501 while meeting or exceeding OEM expectations for a tool-free install.

Precise fit and compatibility

Dimensions are 14 inches in length with a 6-3/8 inch outer diameter and 2-inch open ends. This set is intended for 2-inch open-end systems only and will not fit older pre-2018 models or any spa that uses threaded filters. If you’re upgrading from a ceramic Tri-X system (78372), this high-efficiency fiber option offers a robust alternative.

Pro Series filtration you can feel

• Advanced 3 oz Pro-Grade Media: Triangular Trilobal fibers with integrated Dirt-Locking capture fine debris down to 10 microns, delivering high-density filtration and a balanced-flow that helps maintain water clarity without overburdening the pump.
• Non-Clumping Structural Integrity: A reinforced center core and chlorine-resistant end caps protect against cracking under pressure. The rigid anti-collapse design keeps pleats evenly spaced, making rinsing easier and extending service life with proper care.

Care, maintenance, and lifespan

• Rinse only; do not backwash to preserve filter media and flow characteristics.
• Expect extended service life when paired with regular maintenance; commonly 12–24 months with proper care.
• Handle with care during cleaning to preserve the integrity of the end caps and core.

In short, this Swimara 2-Pack is crafted for reliability and ease, offering a practical, high-performance filtration option for Hot Spring Limelight spas. Use it as a straightforward upgrade, a reliable OEM-compatible replacement, or a proactive way to refresh dual filtration without guesswork.
