[Advanced 3 oz Pro-Grade Media] Our Pro Series is powered by premium triangular Trilobal fibers with integrated Dirt-Locking technology, capturing fine debris and contaminants down to 10 microns. This high-density 3 oz advanced media provides significantly more surface area than standard filters, maintaining a powerful "Balanced-Flow" that ensures superior clarity while protecting your pump from strain. [Non-Clumping Structural Integrity] Built for durability, our filters feature a reinforced center core and chlorine-resistant end caps to prevent cracking under high pressure. The rigid anti-collapse structure prevents pleats from "bunching," making the rinsing process 50% easier and extending the professional-grade service life to 12–24 months with proper maintenance. Note: Do not backwash; rinse only. Keep your spa water fresh, clean, and flowing smoothly with the Swimara FC-2402 Hot Tub Filter Cartridge. Designed for reliable performance, this filter is built to match many of the most common spa systems used in LifeSmart, FreeFlow, and AquaTerra hot tubs. Whether you’re replacing an old cartridge or upgrading from another brand, installation is quick and worry-free thanks to precise OEM-level dimensions, a closed top with string handle, and a 1-1/2" MPT threaded bottom. This filter replaces several well-known filter codes used across popular spas, including FC-2402, 303279, 78460, 5CH-37, and PFF42TC-P4, providing a dependable alternative to expensive OEM cartridges. The high-density pleated media offers 42 sq.ft. of filtration area made from durable 3oz trilobal polyester, capturing oils, hair, lotion residue, and fine debris down to 10 microns while keeping water flow strong. With reinforced PVC core construction and corrosion-resistant bonded end caps, this cartridge is built to withstand high-pressure cycles without deforming. It is fully washable and reusable, helping you reduce replacement frequency and long-term maintenance costs while supporting more eco-friendly spa care. Ideal for maintaining clear, refreshing water throughout repeated spa use, this filter delivers reliable performance for 6–12 months depending on water quality and usage.
