Item Description




    FloPlus™ cartridges utilize a revolutionary new technology that significantly enhances the traditional Fibredyne® product, making it possible to obtain cyst reduction in a cartridge that functions like a nominal 10-micron cartridge.

    This product boasts extremely low pressure drops and high flow rates - comparable to 10-micron (very open) carbon cartridges. Its efficiency is so high that a 0.5-micron rating is possible, which means that cysts and very small particles can be removed to create cleaner, safer water.

    This product is ideal for applications where pressure drop and low flow have been chronic problems in the past, as well as whole house water treatment with the addition of cyst reduction. However, it will address the needs of any end user looking for a product that offers high flow, low pressure drop, infrequent cartridge changes and cyst-free water.


    • Nominal 0.5-micron rating
    • 99.95% reduction of Cryptosporidium and Giardia cysts
    • Premium dirt-holding capacity
    • Outstanding chlorine taste & odor reduction
    • True depth filtration which offers greatest life of any cyst-capable carbon cartridge
    • Pentek is the largest brand in the filtration industry
    • Pentek is the originator of carbon block production technology
    • Pentek is the largest producer of carbon blocks worldwide


    • High flow rates and low pressure drop similar to a nominal 10-micron cartridge
    • Delivers optimal cyst reduction for whole house carbon treatment
    • Maximum life - dirt-holding ability of a 10-micron carbon block with the particulate efficiency of a 0.5-micron cartridge

    • High flow applications (>25 gpm possible)

    Radial flow cartridges are ideal for 'whole house' or other point-of-entry applications due to their high flow rate and low pressure drop compared to standard GAC and carbon block cartridges


    • Provides effective chlorine taste & odor reduction*
    • BB cartridges are ideal for point-of-entry (POE) and other high flow rate applications
    • Unique design reduces carbon fines in filtered water
