If you need a robust, affordable replacement cartridge that matches the Sta‑Rite PLM150 footprint and performance, the Lanmun 27002-0150S is built with a reinforced triple-leaf filter fabric and heavy‑duty end caps to withstand typical pool chemicals and repeated cleanings. It delivers a large filtration area in the familiar 18.3" x 12.9" size and includes compatibility with the 24800-0121 air bleed assembly used on many System 2 setups. This listing describes the design, benefits, and practical details so you can confirm fit and care for optimal life.

Will the 27002-0150S fit my existing Sta‑Rite PLM150 housing?

Yes — the Lanmun 27002-0150S is dimensioned to match the PLM150 cartridge envelope and connect with the same top-mount hardware. It uses the same 18.30" height and 12.90" diameter so it slides into the module without modification. You should still verify port alignment and top cap interface before final installation.

• Dimensions: 18.30" height × 12.90" diameter
• Designed for Sta‑Rite PLM150 and System 2 modular media
• Compatible with 24800-0121 air bleed assembly fittings

How does the triple-leaf fabric improve filtration compared to standard cartridges?

The cartridge uses a trilobal, triple-layer pleated cloth that increases surface area and traps fine particles more efficiently than single-layer media. The pleat belts are reinforced to resist stretching and tearing during cleaning cycles, which keeps performance steady over time. This construction helps maintain flow rates while capturing contaminants that shorten pump and chemical life.

• Triple-leaf (trilobal) filter fabric for greater surface area
• Anti-stretch pleat belts reduce tear risk during cleaning
• High-pressure end caps resist chemical degradation

How long will a Lanmun 27002-0150S cartridge last and how should I maintain it?

With routine backwashing (if applicable), weekly rinses, and periodic deep cleaning, expect practical life of around 12–24 months depending on pool load and chemical balance. The cartridge cleans easily with a hose or filter cleaner; avoid aggressive tools that could damage the pleats. Store dry and shaded if you keep a spare to preserve material integrity.

• Typical lifespan: 1–2 years with reasonable maintenance
• Clean with a hose or approved filter cleaner; avoid wire brushes
• Inspect pleats and end caps for cracks before reinstalling

Who this replacement is for: pool owners and service technicians who operate Sta‑Rite PLM150 or System 2 modular media filters and want an economical, performance-focused replacement cartridge.
