String Wound Filter Cartridges – Slimline & Big Blue | 10", 20", 30" | 1 to 100 Micron

Durable, High-Capacity Sediment Filtration for Residential & Industrial Applications

Our premium string wound filter cartridges are ideal for effective sediment removal in both residential and commercial systems. Made from high-grade polypropylene yarn tightly wound around a rigid core, these cartridges offer high dirt-holding capacity and are suitable for a wide range of water types including borehole, municipal, and rainwater.

Key Features:

• Wide Micron Range: From 1 to 100 micron for tailored sediment removal.

• Depth Filtration: Gradient density structure captures particles throughout the entire cartridge depth.

• Chemical Resistance: Compatible with a wide range of water chemistries.

• High Dirt-Holding Capacity: Reduces pressure drop and extends time between replacements.

• NSF Certified Polypropylene Material (where applicable): Safe for use in potable water systems.

• Universal Fit: Designed for standard and Big Blue filter housings.
