Carbon Block Filtration
Pentek EP Series Carbon Block Cartridges
EP Series cartridges are **nominal 5-micron carbon briquettes** with a high-porosity design and Endurawrap® pre-filter. They reduce chlorine taste & odour and fine sediment while maintaining low pressure drop, making them ideal as polishing or pre-filters in residential, foodservice and light-commercial systems.
Why It Matters
Key Benefits
Effective Taste & Odour Improvement
Bonded PAC carbon significantly reduces chlorine taste & odour and general bad tastes, helping water taste cleaner and more appealing.
High Dirt-Holding Capacity
The high-porosity carbon and gradient-density structure allow the cartridge to hold more sediment before plugging, extending service life.
Protected by Endurawrap®
A polyolefin bilaminate pre-filter wraps the block to trap coarse particles first, protecting the carbon core and maximising utilisation.
Residential POE/POU systems, foodservice beverage equipment, RO post- or pre-filtration, and general-purpose chlorine taste & odour plus fine sediment reduction.

Chlorine taste, odour and fine sediment can make water unappealing and clog downstream filters. EP Series cartridges tackle both in a single element—helping systems run cleaner with fewer call-backs.
