Why customers choose Cera Garden

Upgrade your spa routine with the POOLPURE Replacement Spa Filter in a 5x13 footprint. This independent spare part is designed to fit a broad range of popular models, offering a convenient, cost‑effective alternative without compromising filtration. The 5x13 size fits standard spa housings, featuring a length of 13 5/16 inches, an outside diameter of 5 inches, and top/bottom holes at 2 1/8 inches for a reliable seal and steady water flow.

Filtration technology

The trilobal filtration fabric design increases adsorption surface area, helping to capture more dirt and sediment while maintaining water clarity with frequent use. A dedicated 50‑micron filtration layer provides an extra level of particle control, supporting clearer water over time.

  • Trilobal Filtration Fabric: three times the adsorption surface area versus conventional fabrics.
  • 50‑Micron layer: targets fine particles such as hair, leaves, dust, and sand.

Quality and standards

  • NSF/ANSI 50 certified (IAPMO tested) for filtration performance
  • PHTA member, aligning with industry standards for spa filtration
  • Patented Dirt-Locking Technology for easier cleaning and reuse

In real-world use, these features translate to more straightforward maintenance and consistent water clarity, even with frequent spa sessions. While performance can vary with usage, the design emphasizes reliability and long‑term value.

Maintenance and compatibility

This replacement is a compatible spare part reference, not an official manufacturer part. It is designed to fit a variety of 5x13 spa filters and can be rinsed and reused to reduce maintenance time and costs.
