  1. Patented Electronic Digital Demand Module
    Solid-state electronics record usage patterns and control regeneration frequency based on predicted needs. Full menu-driven options.
  2. Full One-Inch Riser
    One-inch diameter for increased flow rates, which ensures that household demand is adequately met.
  3. Carbon for Chlorine Taste and Odor Removal
    The ERR 3500 unit features coconut shell carbon for chlorine taste and odor
  4. Multi-Wrap Fiberglass Reinforced Resin Tank
    Polymeric tank liner with a figerglass wrapped exterior for strength. Doesn’t deteriorate, rust, or corrode.
  5. Self-Cleaning Distributors
    Distributors exhibit excellent flow rates and are cleaned automatically by counter-current water pressure.
  6. Positive Action Brine Valve
    Snap-together construction eliminates use of solvents that may contaminate water. Positive action helps prevent overfilling.
    Patented Six/Eight-Cycle Valve with Easy-Clamp Ring and Patented Teflon® Discs
  7. Patented Stratified Resin Bed
    Patented mix of stratified resins provides superior filtration and iron removal without sacrificing flow rate capability.
  8. Washed Quartz Underbedding
    Washed quartz doesn’t impart hardness into softened water and allows for more powerful “piston effect” during counter-current cycles.
  9. HydroLinkTM Remote (patent pending)
    Two-way remote technology that makes it possible to control and monitor the Series 3500 water conditioner from anywhere in the home. (Tested to comply with FCC standards IC3590A-7695) Multi-Media System – Extends Resin Life
    Carbon removes harmful chlorine which can attack the resin, extending the life of the system.
    24-Volt Transformer – ENERGY STAR ®qualified
    Barium and Radium
    This refiner has been tested and certified by NSF International and WQA against NSF/ANSI Standard 44 for the reduction of Barium and Radium 226/228.

1 1Intermittent flow rate does not represent the maximum service flow rate used for determining the refiners rated capacity and efficiency. Continuous operation at flow rates greater than the certified flow rate may affect capacity and efficiency performance. The validity of this flow rate is verified by NSF.
