Unicel C-7483 Replacement Filter Cartridge – 81 sq ft

Part # C-7483 — a high-quality cartridge filter replacement designed for many residential pool and spa filtration systems. This cartridge restores filtration efficiency and helps maintain clear, clean water by capturing dirt, debris, and fine particles.

Key Features

  • 81 square feet of filter media for effective filtration and extended run times.
  • Approximately 176 pleats — provides increased surface area for improved dirt capture.
  • Dimensions: ~7″ outside diameter × 19⅝″ length, with 3″ inside-diameter open-top and open-bottom ports for easy installation.
  • Durable polyester media and reinforced end caps for long service life under pool/spa conditions.
  • Compatible with a wide range of pool filters originally using 81 sq ft cartridges, often as replacement for original OEM cartridges.

Typical Applications

Use this cartridge when the existing filter element becomes clogged, torn, or collapsed, leading to reduced flow, higher pressure, or poor water clarity. Ideal for residential in-ground or above-ground pools and spas using cartridge-type filters sized for 81 sq ft elements.

Installation & Compatibility Notes

Shut off the pump and relieve system pressure before servicing. Remove the filter tank lid or clamp and extract the old cartridge. Clean the tank interior thoroughly and inspect sealing surfaces. Insert the new C-7483 cartridge — ensure it seats properly with open ports aligned. Reassemble the filter, refill/prime the system, and confirm normal pressure and flow before resuming regular operation.

Why Choose This Cartridge?

The C-7483 delivers reliable filtration, strong dirt-holding capacity, and long service life, making it an excellent replacement for worn or underperforming cartridges. It helps restore optimal flow and water clarity without the need for a full filter replacement.

Maintenance Tips

  • Inspect and rinse the cartridge regularly — ideally when system pressure rises 8–10 psi above clean startup pressure.
  • Deep-clean or replace the cartridge when pleats begin to show wear, flattening, or if end caps crack or deform.
  • Keep a spare cartridge on hand to rotate during cleaning or replacement, minimizing downtime.
  • Ensure filter tank O-rings and sealing surfaces are clean during maintenance for a proper seal and efficient operation.
