Overview

Meet the POOLPURE PLFPA100N, a 100 sq ft pool and spa filter cartridge designed to fit a range of popular models. This replacement part supports clear water and dependable filtration for family pools and hot tubs alike.

Compatibility at a glance

Designed to replace PA100N-4, Unicel C-7487, Filbur FC-1270, and Hayward CX870RE and related models. Key measurements include a length of 25.5 inches, outer diameter of 7 inches, and 3 inch top and bottom openings. Note that original brand names are for reference only.

Filtration technology you can sense

With Dirt-Locking technology, the PLFPA100N uses trilobal filtration fabric to achieve an approximate 50 micron filtration, capturing hair, leaves, dust, sediment, and sand with efficiency. The design aims to reduce debris reaching your pool equipment, helping maintain clear water and steady flow.

What to expect in daily use

The 25 percent thicker filtration fabric, reinforced end caps, and central support team up to extend service life by an estimated 20-30 percent compared to standard cartridges. The result is longer intervals between replacements and fewer mid-season changes.

Maintenance and care

  • Clean the cartridge periodically—ideally monthly or when the pressure rises to the target level.
  • ⚠️ Not for backwashing — this cartridge is not designed for backwashing and may crack if forced.
  • Rinse and inspect seals to preserve a tight, leak-free fit.

Quality and trust

POOLPURE is a proud member of the filtration community. The PLFPA100N carries NSF/ANSI 50 certification and is backed by IAPMO testing, with industry recognition through Pool & Hot Tub Alliance membership. Real-world testing includes athletic environments and media coverage by NBC Local.

Practical setup tips

  • Verify compatibility with your model list: PA100N-4, C-7487, FC-1270, CX870RE, CX870-XRE, C4000, C4020, and more.
  • Prepare for straightforward replacement by aligning the 3 inch top and bottom openings and length of 25.5 inches.

Note: For best results, follow your pool’s maintenance schedule and monitor pressure gauges to determine cleaning frequency. This POOLPURE cartridge is designed as a compatible, affordable upgrade—not a guaranteed outcome.
