    ROsave.Z Depth Filters are made in the USA and specifically made for reverse osmosis pretreatment applications. This premium sediment filter will protect the more expensive carbon blocks and prolong overall filter set life to decrease over 
    ROSave.Zs' Z.Plex technology provides great performance:

    • Up to twice the life of conventional depth filters
    • Up to 50% lower pressure drop
    • Up to 100% greater dirt holding capacity
    • Superior SDI reduction
    • Melt-bonded exterior ensures no media migration
    • Provides lower total cost of filtration operations
    • NSF 42 certified, FDA compliant


    BRS Universal Carbon Blocks are manufactured using high performance catalytic active carbon combined with a new binder system technology which maximizes the availability of the critical catalytic sites. The combination of advanced carbon technology, increased volume of carbon contained in each filter and proprietary manufacturing processes delivers exceptionally high chloramine, chlorine, VOC and general chemical performance.

    • NSF Certified
    • Specifically formulated for superior Chloramine reduction 
    • 1 µm (micron) Nominal Filtration* 
    • Chlorine 35,000 @ 1 GPM**
    • Chloramines 3,500 @ 0.5 GPM***
    • High chemical adsorption
    • 30% more carbon than standard blocks****


    BRS Pro Deionization Resins are packaged in foil-lined 4mm Mylar bags and vacuum sealed to maintain maximum storage life and effectiveness. 


    Note: Membranes are not included in standard filter replacement kits. Membranes should be replaced as needed.
