    The PB1 is a powerful, multifunctional filter cartridge for residential and commercial water purification systems.

    Heavy Metals Reduction
    KX PB1 extruded activated carbon filters reduce soluble lead using an ion-exchange filter medium with high specificity for soluble lead. Particulate filtration is used to intercept insoluble lead-containing particles. Standard 2.50” O.D. x 9.75” L filters will reduce lead, meeting the performance requirements of NSF Standard 53 protocol for over 2,500 gallons when operating at a flow of 0.75 GPM.

    Chemical Adsorption
    KX PB1 filters offer high levels of chemical reduction in potable drinking water, including chlorine and other compounds that contribute to taste and odor.

    Particulate, Cyst and Turbidity Reduction
    KX PB1 filters provide >99.98% reduction of 3-4 µm particulates, >99.96% reduction of 1-2 µm particulates, and are high performance sediment filters with extended life. Graded-density prefiltration combined with high dirt capacity extruded activated carbon provide several times greater life than molded filters.

    Standard filters are finished with an outer polypropylene spunbonded prefiltration medium overlying a second polypropylene melt-blown prefiltration medium. A protective polypropylene netting is applied to the exterior of the cartridge. Polypropylene end caps with compression gaskets fit most standard housings.


    KX PB1 filters consist of activated carbon particles fused into a uniform block with enhanced adsorptive capacity and efficiency. KX PB1 filters flow in a radial (outside-to-inside) direction, providing increased dirt capacity and low pressure drop. Unlike granular activated carbon (GAC) filters, KX PB1 cartridges will not channel or bypass due to the extreme uniformity of their extruded activated carbon core. Service life of the KX PB1 filter is greatly extended by two layers of prefiltration media consisting of a 15 µm polypropylene spunbonded outer prefiltration layer and a 5 µm polypropylene melt-blown inner layer.

    • Maximum service life and resistance to fouling
    • Graded density prefiltration design
    • Manufactured using FDA-compliant materials

    Performance of a given KX PB1 extruded carbon filter varies in direct proportion to the total weight of carbon in each filter. For example, a 4.25” O.D. x 20” L KX PB1 filter contains approximately seven times as much activated carbon as a 2.50” O. D. x 9.75” L KX PB1 filter, and will therefore have seven times the rated chlorine and lead-adsorption capacities when operated at seven times the rated flow of the smaller cartridge. Hence, rated flow is based on maintaining identical contact/residence times for all filters.

    Chlorine capacity is the capacity in gallons during which the filter will remove > 95% of influent free available chlorine (2 ppm) when operating at a given flow and has been tested using the NSF Standard 42 protocol for chlorine reduction.

    • Nominal particulate rating (0.5 µm) is for >85% of a given size as determined from single-pass particle counting results.*
    • Absolute particulate rating (1 µm ) is for >99.9% of particles of a given size as determined from single-pass particle counting results.**
    • *Nominal Filter Rating: Filter rating indicating the approximate size particle, the majority of which will not pass through the filter. It is generally interpreted as meaning that 85% of the particles of the size equal to the nominal micron rating will be retained by the filter. (WQA Glossary of Terms, Third Edition, 3-97).
    • **Absolute Filter Rating: Filter rating meaning that 99.9% (or essentially all) of the particles larger than a specific micron rating will be trapped on or within the filter. (WQA Glossary of Terms, Third Edition, 3-97)


    KX PB1 filters are not to be autoclaved or steam-sterilized.

    Use KX PB1 carbon filters only with microbiologically safe and adequately disinfected water. Activated carbon filters are not designed to kill or remove bacteria or viruses. Actual results obtained will vary with various combinations of organic contaminants, changes in pH or other conditions encountered in actual use.

    KX PB1 filters are designed to fit most standard household and commercial or industrial housings.

    This cartridge must be placed in an appropriate housing and flushed for a minimum of 5 minutes prior to use. Use only with microbiologically safe and adequately disinfected water.
