Why Choose the Unicel C-8414 Filter Cartridge

OEM-Level Compatibility

The Unicel C-8414 is a direct replacement for Pentair Predator 59054300 and Clean & Clear 150 filter cartridges. Built to exact OEM specifications, it installs perfectly into your filter housing without adjustment or modification.

Superior Filtration Technology

Featuring precision-pleated Reemay® filter media, the C-8414 captures fine debris, dirt, pollen, and oils that other filters miss. Its open-core structure allows high flow rates and reduced resistance, keeping your pool water balanced and visibly clear.

Longer Cleaning Cycles

Thanks to its large 150-square-foot surface area, this cartridge holds more dirt before cleaning is required. You’ll spend less time maintaining your filter and more time enjoying your pool.

Built to Last

Unicel’s filters are made in the USA and constructed with durable PVC cores, thermally bonded seams, and chemical-resistant end caps that withstand years of chlorine exposure, pressure, and heat without breaking down.

Installation & Maintenance Guide

1. Turn Off the Pump: Always power off your pool pump and release filter pressure using the relief valve.

2. Remove the Old Cartridge: Open the tank clamp, remove the lid, and lift out the old filter.

3. Clean the Housing: Rinse away dirt and debris from the tank body before installing your new cartridge.

4. Insert the New Filter: Slide the Unicel C-8414 into place, ensuring it seats evenly over the internal standpipe.

When to Replace Your Filter Cartridge

Even the best filters wear over time. Replace your Unicel C-8414 when you notice:

• Frequent cleaning is required (more than every 2–3 weeks)

• Pressure remains high after cleaning

• Visible cracks or frayed pleats

• Persistent cloudy water or poor flow

Most pool owners replace their filter cartridge every 12–24 months, depending on water conditions and system usage.
