    FilterCor 2.5" x 10" 0.5 Mic Depth Wound Poly Sediment Filter - FCP0.5R10P

    The FCP0.5R10P by FilterCor is a depth wound, polypropylene sediment filter that increases in density from the outside surface going towards the center. This allows for high sediment retention capacity since the trapping of sediment particles is spread throughout the entire filter's volume. Use this filter to protect against concentrated acids and alkalis, strong oxidizing agents, corrosive fluids, and gases.

    10" Standard 1 micron filter in 2 3/4" x 9 3/4"

    KX Technologies® and Filtrex Technologies®, both Marmon Water/Berkshire Hathaway companies, have teamed up to combine the very best of their MATRIKX® and GREENBLOCK® carbon block lines, into a single world class product offering. The new and improved product line is the result of decades of experience in R&D, design, formulation, and manufacture of high-performance carbon block filters. MATRIKX® ChloraGuard® filters, powered by GREENBLOCK® are made from 100% coconut shell carbon, a renewable, and ecologically sustainable material. The carbon is processed into blocks using a unique binder system and proprietary manufacturing techniques to produce filters with a greater number of micro-pores and available carbon surface area, which display superior adsorption capacity and kinetic dynamics.

    The KX Matrikx +CTO Carbon Block Filter 32-250-125-975. 2.5" × 9.75" is certified to reduce chlorine taste and odour from your drinking water. It delivers you with the best possible combination of meaningful innovation, useful features and lasting value.
    These filters are optimized for applications where they perform the role of both a sediment and activated carbon filter. The extrusion process allows the production of a carbon block with more carbon, but a lower pressure drop. This enables a MATRIKX CTO filter to deliver extended life while removing sediment, chlorine taste and odor and organic contaminants from water, aqueous solutions or suspensions. The MATRIKX CTO is also widely used in filtering organic solvents. The MATRIKX CTO KX Filter is ideal for use in residential and commercial water purification systems, food service, pre- and post-RO systems.

    Spectra Pure SilicaBuster™ Super DI™ Color Indicating Multi-Layer De-Ionization Cartridge - DI-SB-CI-10HC

    * Color-Indicating SilicaBuster™ Super DI™ cartridge provides a color change to show remaining capacity without metering.

    SpectraPure® SilicaBuster™ Super DI™ Multi-Layer De-Ionization Cartridges are fabricated with the highest grade custom-blended resins for ultra-pure water. They are capable of producing 18 meg ohm-cm resistivity water. They are the first de-ionization cartridges designed to reduce silica, nitrates and phosphate levels into the low ppb range. These newly formulated cartridges far exceed the performance of previous cartridges, offering enhanced contaminant removal, longer life and higher purity. This cartridge needs resistivity or TDS monitoring to determine when it is exhausted.

    Caution: The deionization cartridge life is greatly reduced when operated on low pH waters, or water with high CO2 (carbon dioxide) levels. The exact cartridge life will vary greatly with pH, carbon dioxide levels, and TDS etc. in your RO water or the feed water supplying the RO system. Aeration or de-gasification of RO product water is recommended for such waters for removal of carbon dioxide.

    ****Fits most standard 10" RO & RO/DI Systems including KENT, CoraLife, Seachem, AquaFx, Vertex, SpectraPure.****
