Why customers choose PatioZora Garden

Crystal-clear spa water with dependable filtration

The POOLPURE C-5345 Spa Filter is a ready-to-use, 2-pack replacement designed for broad compatibility with popular spa models. It’s NSF/ANSI 50 certified, supporting reliable filtration and water quality during regular spa sessions. The cartridge is built to slip into place as a drop-in replacement, offering an easy upgrade path for many spas and hot tubs without aftermarket guessing.

Key measurements include a length of 10 1/8 inches, an outer diameter of 5 5/16 inches, and top/bottom openings of 2 1/8 inches. With a filtration area of 50 square feet, the filter balances strong debris capture with smooth water flow, helping you enjoy a steady, inviting soak after each fill. The media uses trilobal filtration fabric, designed to trap hair, dust, and fine particulates while preserving optimal water movement.

Why this filter stands out

  • Dirt-Locking technology captures more debris than standard cartridges, contributing to consistently clear water across use cycles.
  • Easy-cleaning fabric structure makes rinsing gentler on the cartridge, helping it feel like new after regular maintenance.
  • Broad compatibility covers models such as PLBS50, PDC530-AFS, C-5345, FC-2970, 817-0014, 173584, R173584, X268519, 10419, 14513, 50451, and S2/G2 Spa.
  • Industry backing and a legacy of trusted performance, supported by millions of pool and spa owners worldwide.

In real-world use, imagine steadier clarity after weekend spa gatherings or daily soaks—the water feels inviting, and filtration stays up to the task. When it’s time for care, a simple rinse helps preserve flow and efficiency without harsh scrubbing.

Care, installation, and ongoing maintenance

  • Rinse the cartridge monthly to remove accumulated debris and maintain steady flow.
  • Do not backwash the cartridge, as this can cause cracks or permanent damage.

What you get: a 2-pack of POOLPURE Spa Filters designed to fit a range of common spa models, backed by certification and a commitment to reliable filtration.
