    APEC Ultimate high capacity pre-filter set is made in USA with high quality filtration components to provide a longer lasting filter set to protect and prolong the lifespan of your reverse osmosis system. Premium quality filter set lasts over 12 months for fewer filter change outs and high performance contaminant removal. These standard size filters are compatible with APEC RO-45, RO-90, RO-PH90, RO-PERM, RO-PUMP, RO-Hi, WFS-1000 and all other 10" standard size under counter reverse osmosis systems.

    All US Made Super High Capacity Filters

    1st Stage: High-Grade 5 micron 10" high-capacity polypropylene sediment filter -removes dust, particles, and rust. 100% pure polypropylene depth filter with exceptional dirt-holding capacity translates to longer life and fewer change-outs than existing string-wound or resin-bonded filters.

    2nd and 3rd Stage: Premium Extruded Carbon Block 10" -gets rid of unpleasant chlorine, tastes, odors, cloudiness and colors. Also removes VOCs and other common chemicals from the water. APEC's extruded carbon block filters consist of activated carbon particles fused into a uniform block with enhanced adsorptive capacity and efficiency. Unlike granular activated carbon (GAC) filters, these extruded carbon block cartridges will not channel or bypass due to the extreme uniformity of their extruded activated carbon core.

    For over 20 years, APEC has been an industry leading manufacturer of high performance RO systems.

Product's Review
    1. Thank you for the reminder Review by Ron Popko

      Thank you for the reminder to change the filters in my RO 45 system. The
      entire process of buying and installing the unit could not have gone any
      easier. I really enjoy the quality of water that it produces, as water in
      Phoenix, AZ is the pits. (Posted on 6/3/2014)
