Swimara Ultra Series 5oz Trilobal Pool Filter Cartridges for CCP420 & Waterway 425 – 4-Pack

Overview

Meet the Swimara Ultra Series, a 4-pack of 5 oz+ trilobal pool filter cartridges designed as a precise, drop-in replacement for Pentair CCP420 and Waterway 425 systems. The 1:1 fit aims for a seamless, leak-free seal right after you open the filter tank—no tools needed for setup.

Key Benefits

• Ultra 5 oz Trilobal Fabric: 60% thicker than standard, with triangular fibers that help trap fine debris as small as 10 microns.
• Rugged Construction: A reinforced anti-collapse core keeps pleats stable during high-pressure cycles, preserving flow and performance over time.
• Efficient Filtration: 420 sq ft of filtration area and optimized spacing reduce backpressure, potentially lowering energy use and pump wear.
• Longevity & Value: Engineered for durability with a service life that can extend up to 24 months under typical conditions, depending on use.
• Professional Tier: The Ultra Series represents Swimara’s flagship for high standards of pool health and clarity.

How It Fits Your Pool

These cartridges are a verified alternative to Unicel C-7471 and FC-1977 and are compatible with OEM numbers 178584 and R173576. The direct drop-in design supports a 100% leak-free seating when installed correctly, promoting reliable performance without the need for tools once the tank is opened.

Real-World Scenarios

Ideal for pools facing heavy bather loads, pollen seasons, or post-storm cleanup, where robust debris capture and durable construction matter most. A 4-pack ensures you have replacement ready for routine maintenance, seasonal upkeep, or sudden need.

Quality & Longevity

Swimara’s Ultra Series emphasizes durability and consistent filtration efficiency. With a 420 sq ft filtration area and high-flow spacing, the design supports steady water movement and prolonged cartridge life, aligning with professional-grade expectations for backyard pools.

Note: While results vary with usage, the combination of high-capacity filtration and a reinforced core aims to help you maintain clear water and reduce the frequency of cartridge changes.
