SpiroPure Replacement for PA80 C-8600 is a direct-fit pool and spa filter cartridge engineered to restore efficient filtration in Hayward CX800RE, C1500 and equivalent systems.

If your pool or hot tub is showing slower circulation, cloudy water, or higher debris load, replacing the cartridge with a correctly sized, high-capacity filter is one of the fastest ways to get clarity back. The SpiroPure PA80/C-8600 replacement cartridge is built to the same outer dimensions and connection style as common OEM parts, while using durable media and a reinforced core to maximize dirt-holding capacity and structural life.

How does this cartridge fit my existing Hayward or C-series filter housing?

The SpiroPure replacement is designed to match the common PA80/C-8600 physical dimensions and connection types so it installs like the original. It has open top and bottom 4-1/16" ports for direct compatibility with Star Clear II, C1500, C-1500 and similar housings.

• Outer diameter: 8 1/2" and length: 17 3/8" for correct housing fit.
• Top style: 4-1/16" open; bottom style: 4-1/16" open—fits standard collars and end fittings.

What filtration performance can I expect from the SpiroPure cartridge?

This cartridge uses 75 square feet of filtration media arranged to increase dirt-holding capacity without sacrificing flow. The media traps fine particles common in pools and spas while the robust inner core prevents collapse under pressure, keeping circulation consistent across service life.

• Media area: 75 square feet for extended run times between cleanings.
• High dirt-holding design reduces the frequency of rinsing and replacement.
• Strong inner core maintains shape to preserve flow and filtration efficiency.

How easy is it to install and maintain this replacement cartridge?

Installation is straightforward because the cartridge follows OEM dimensions and port styles—simply remove the old element, rinse or clean the housing, and seat the SpiroPure cartridge into place. Maintenance is basic: periodic rinsing with a hose and occasional deep cleaning or replacement depending on use and water conditions.

• Tool-free swap: fits directly into compatible filter housings.
• Routine maintenance: hose-rinse after every few weeks of heavy use or monthly for typical residential pools.
• Replace when media shows wear, excessive staining, or flow drops despite cleaning.

Which systems and model numbers are compatible with this cartridge?

This replacement is compatible with a wide range of common pool and spa filter models. Check your old cartridge part number or measure the cartridge to confirm the match before purchasing.

• Compatible models include Star Clear II C1500, C-1500, C-800, C800 and similar housings.
• Direct replacements for Pleatco PA80, Unicel C-8600, Hayward CX800RE, Filbur FC-1280.
• Works in many hot tub and small pool systems that accept 8 1/2" x 17 3/8" cartridges with 4-1/16" open ports.

Who this is for: Pool and spa owners, service technicians, and maintenance professionals who need a reliable, cost-effective replacement cartridge that mirrors OEM fit and function.
