•

Uses mixed-bed ion exchange resin to remove dissolved minerals (calcium, magnesium, iron, and others) from tap water, producing deionized water with 0 PPM TDS output.* No electricity or pump required — runs on standard hose pressure.

How It Works

  1. Tap water enters the system under normal hose pressure
  2. Mixed-bed resin captures dissolved solids and exchanges them for H⁺ and OH⁻ ions, which recombine as water
  3. Water exits at 0 PPM TDS*

Why It's Used
Because DI water contains no dissolved minerals, manufacturer states it evaporates without leaving mineral spots, eliminating the need for towel drying after a rinse.

Applications

  • Vehicles and fleets — cars, trucks, motorcycles, RVs, mobile detailing, commercial car washes
  • Marine and aviation — boats, yachts, aircraft; manufacturer states it helps prevent mineral etching on gel coat, fiberglass, polished aluminum, and windshields
  • Glass and solar — window cleaning, solar panel maintenance, greenhouse glass

Note on Performance
*Manufacturer states TDS and spot-removal claims assume typical municipal water conditions. Elevated silica or dissolved CO₂ may reduce resin efficiency and affect output TDS.
