Unicel® C-8417 Replacement Filter Cartridge – 175 Sq Ft

Fits Hayward CX1750RE Filter Housings

Think of the C-8417 as the gold-standard “coffee filter” for your Hayward CX1750RE—except it catches algae, pollen, and debris down to 25 microns instead of grounds. With 175 sq ft of heavy-duty polyester media and 210 pleats, this cartridge gives you longer filter cycles, less backwashing, and more cannonballs in your future.

Key Features

• Generous Media Area: 175 sq ft of 4-oz basis-weight polyester for massive dirt-holding capacity.

• 210 Pleats: Maximizes surface area so you clean less often.

• 25 Micron Rating: Captures fine particles—think dust, algae, and plant debris.

• Universal Open End Caps: 4″ inner-diameter molded gaskets ensure a perfect seal.

• Drop-In Fit: OEM-exact replacement for Hayward CX1750RE filter housings.

• Made in USA: Quality construction built to last.

Safety & Maintenance Tips

1. 🔧 Always shut off the pump and relieve system pressure before swapping cartridges.

2. 📈 Monitor pressure gauge: Replace when the differential rises 8–10 psi above start-up—your cue that it’s time.

3. 🗓️ Routine replacement: Every 1–2 seasons (or sooner in dusty/tree-lined yards) keeps flow high and energy use low.

4. ♻️ Responsible disposal: Used cartridges trap organic debris; dispose per local regulations to avoid clogging drains.
