Pentair Carbon Block Filters


Our Pentair Carbon Block Filters remove chlorine, VOC’s and chemicals from your water to improve taste, odour and appearance. Constructed from bonded powder activated carbon with a high surface area these carbon filters have an exceptional chlorine reduction capacity and outperform most other carbon block cartridges on the market. The impressive capacity means filters need changing less often and are suitable for both domestic and more demanding commercial applications. These 20” Pentair Carbon Block Filters are available in both regular and large diameter (or ‘BB’) sizes.

Why Choose Our Pentair Carbon Block Filters?

  • Improves the taste, odour and appearance of your water
  • Outer wrap prevents premature blinding from sediment

Whether you are looking for a carbon filter for drinking water, for a manufacturing process or as a pre-filter for a reverse osmosis system our Pentair Carbon Block Filters offer unrivalled performance. With an outer wrap which acts as a sediment filter to protect the carbon block from premature blinding and maintaining minimal pressure drop.

EPM-20: This 10 micron regular diameter 20” carbon block has been cleverly constructed to minimise pressure drop, with an initial pressure drop of just 0.03 bar at 7.8 litres per minute. Offering an impressive chlorine reduction capacity of 22,700L at 2ppm free chlorine.

EP-20BB: This 5 micron large diameter 20” carbon block features a uniquely formulated polyolefin bi-laminate pre-filter, helping to increase the service life of the cartridge by trapping sediment which typically plugs (or ‘blinds’) carbon filters. With an initial pressure drop of 0.14 bar at 15.1 litres per minute. Offering an impressive chlorine reduction capacity of 166,558L at 2ppm free chlorine.

How Often Do I Need To Change These Pentair Carbon Block Filters?
If you can measure (or estimate) the flow throughput you can accurately establish change frequency, as Pentair offer good data on the chlorine reduction capacity of these filters. Where this is not possible it is best practice to change your carbon filter annually for hygiene purposes.

Sarah at Ultra Soft Water Softeners helped to identify a suitable JG replacement connector for tri-flow water filter system. She went extra mile to make sure it was the right one. Really pleased with the service. Even called me to ensure the item was delivered and worked which it did. Thank you & well done.
