Unicel C-8416 150 sq ft Replacement Pool Filter Cartridge
The Unicel C-8416 is a high-capacity, OEM-grade replacement cartridge filter designed for many in-ground pool filter tanks — including housings such as Sta‑Rite Posi-Clear PXC-150 and Waterway Pro-Clean 150 (among others that match the size and port configuration). It delivers reliable filtration, improved water clarity, and long service life compared to generic cartridges.
Key Features
- 150 sq ft of filtration media — large surface area allows for strong debris capture and longer time between cleanings.
- Spun-bonded polyester media — durable and resistant to pool chemicals and repeated cleanings.
- Open 4″ top and bottom end caps with molded gaskets — ensures a tight, leak-free fit in compatible filter housings.
- High pleat count (≈ 177 pleats) — optimizes water flow and maximizes usable filter area.
- Direct-fit OEM replacement for many PXC- or Pro-Clean-style filter housings — simplifies inventory and replacement for service professionals.

Why Use C-8416
With 150 sq ft of media and a robust build, the C-8416 offers excellent dirt-holding capacity and flow performance — reducing cleaning frequency and improving overall filtration efficiency. Its OEM-grade materials and precise dimensions help ensure a secure, leak-free install, which is key for consistent water circulation and pressure maintenance in pool systems.
Maintenance & Care Tips
- Rinse the cartridge regularly (e.g., every 2–4 weeks) or when filter pressure climbs — helps extend media life and maintain flow.
- Use a filter-safe cleaning solution periodically to remove oils, lotions, and organic buildup that plain rinsing won’t remove.
- Inspect end caps, gasket seals, and pleats annually for wear or damage — replace the cartridge if pleats collapse or gaskets show cracks.
- Have a spare cartridge on hand — rotate units so one can dry completely between uses, prolonging overall cartridge life.
When to Replace
Replace the C-8416 when the filter is clogged, flows poorly even after cleaning, pleats are deformed, or when the gasket seals no longer seat properly — all signs that the cartridge has reached the end of its useful life.
