POOLPURE Pool Filter Cartridge Replacement for Hayward C580E PA81 - 4-Pack, 50-Micron Pleated

POOLPURE CX580XRE is a 4-pack replacement pleated pool filter cartridge engineered to fit Hayward C580E/PA81-style systems and deliver fine 50-micron filtration for clearer water.

This POOLPURE replacement cartridge set gives you a direct-fit option for many popular pool filters, including PA81 and Unicel C-7483 equivalents. Each cartridge is built with trilobal filtration fabric, a reinforced core and ABS end caps to improve dirt capture, ease rinsing, and extend service life. The package includes four identical cartridges sized to standard PA81 dimensions so you can replace all elements at once and restore peak filtration performance.

How does this cartridge improve my pool’s clarity?

The CX580XRE uses a trilobal fiber structure and an upgraded 50-micron layer to trap very fine particles that ordinary cartridges miss. That finer capture reduces cloudiness and keeps water visually clearer between cleanings.

• 50-micron high-efficiency layer captures hair, dust, sand, and pollen.
• Trilobal fabric offers three times the adsorption surface area versus standard media.
• Dirt-locking technology reduces re-deposition and eases rinsing.
• Large 81 sq.ft. filtration area supports higher flow with lower pressure rise.

Will these cartridges fit my existing Hayward or Unicel filter?

Yes — the CX580XRE is designed to be compatible with PA81-style and several equivalent OEM cartridges. Check the sizing and port openings to confirm fit before installation.

• Length: 19 5/8"; outside diameter: 7"; top/bottom openings: 3".
• Direct fit for PA81, Unicel C-7483, and other listed equivalents.
• Sold as compatible replacements; verify part numbers and dimensions to confirm.
• Pack of four lets you replace all cartridges simultaneously for balanced flow.

How easy is maintenance and cleaning with these filters?

POOLPURE cartridges are built for straightforward rinsing and reuse. The dirt-locking design releases trapped debris quickly during backwash or garden-hose rinsing, lowering cleaning time and effort.

• Patented dirt-locking structure reduces repeated scrubbing during rinses.
• Reinforced core and thickened polyester extend usable cycles before replacement.
• Simple hose-rinse cleaning restores performance in minutes.
• Reusable design reduces frequency and cost of replacements over time.

Are these cartridges safe and certified for pool use?

• IAPMO tested to NSF/ANSI 50 material safety standards.
• Durable ABS end caps and reinforced core resist collapse under pressure.
