Sediment Filtration
Pentek P Series Spun-Bonded Polypropylene Cartridges
A family of **100% polypropylene, spun-bonded cartridges** with true gradient density. P Series filters provide high dirt-holding capacity without imparting taste, odour or colour—ideal as sediment pre-filters in residential and light-commercial systems.
Why It Matters
Key Benefits
Clean, Neutral Filtration
Manufactured from pure 100% polypropylene fibres designed for purity, so cartridges will not impart taste, odour or colour to the liquid being filtered.
High Dirt-Holding Capacity
Spun fibres form a true gradient density from outer to inner surfaces, capturing larger particles on the outside and finer particles inside for longer life.
Chemical Resistance
Polypropylene construction offers superior chemical compatibility and is not prone to bacterial attack when used within the rated temperature range.
Pre-filtration in residential POE/POU systems, light-commercial water systems, RO pre-treatment, and general-purpose sediment reduction where chemical resistance and media purity are important.

Sand, rust and silt can clog fixtures and foul downstream filters. Pentek P Series cartridges capture sediment efficiently while keeping water chemistry stable—so systems run longer and taste issues stay in check.
