Pleatco PIN20 Replacement Filter Cartridge
Part # PIN20 — a high-quality replacement cartridge by Pleatco designed for above-ground pools and compatible cartridge filter systems. This cartridge delivers reliable filtration performance and improved water clarity for systems requiring the Intex “B”-style or equivalent filter size.
Key Features
- Approximate dimensions: 5 7/8″ diameter × 10 1/16″ length.
- Media surface area around 15–20 sq ft depending on manufacturer packaging.
- Open-hole design on both ends (approx. 1 15/16″ inner diameter) for direct drop-in compatibility.
- Constructed using bonded filtration fabric for enhanced debris capture and increased durability.
- Engineered with a high-flow core to reduce pump strain and maintain stable water circulation.
- Cross-replaces common OEM numbers including Intex 59901W, Unicel C-5315, and Filbur FC-3752.
Typical Applications
This cartridge is ideal for above-ground pool filter systems, especially pools using Intex “B”-style filters. It is used when the existing cartridge becomes clogged, worn, or no longer maintains proper flow and clarity. It helps restore filtration efficiency and is suitable for routine or seasonal replacement.
Installation & Compatibility Notes
Shut off the pump and relieve system pressure before installation. Remove the housing, take out the old cartridge, clean the tank of debris, and insert the new Pleatco PIN20 cartridge. Ensure the cartridge is fully seated and the housing O-ring is in good condition before reassembly. Because both ends are open, confirm your system’s manifold or filter plate matches this style for proper sealing and flow.
Why Choose This Cartridge?
The Pleatco PIN20 cartridge offers dependable filtration, improved water clarity, and longer cleaning intervals compared to many generic alternatives. Its reinforced media and optimized core design support better flow, lower pressure rise, and extended service life.
Maintenance Tips
- Rinse the cartridge with a hose every 4–6 weeks or when system pressure increases 8–10 psi over the clean starting pressure.
- Avoid high-pressure sprayers, which can damage pleats or weaken the filtration material.
- For deep cleaning, soak the cartridge in a filter-cleaning solution to remove oils and fine debris, then rinse thoroughly.
- Store indoors during winterizing or long off-season periods to prevent mildew or material degradation.
