Battery-powered system produces 3 to 5L/day of Type II purified water directly from tap water

  • Supplies purified water at a flowrate of 0.125 gal./min. (0.5L/min.) attaining >1 megohm·cm resistivity at 25°C (77°F).
  • Requires DI-PAK Deionization Cartridge (CPDI000L1), sold separately.

Two-stage purification sequence

  • Activated carbon first removes chlorine and colloids
  • Ion exchange resins remove typical inorganic ions

 Optional Millipak-40 Final Filter connects directly to water supply or faucet to remove bacteria particles >22μm at point of use (requires Millipak-40 thread adapter, MDI0 2AD AP).

System Operation Features

  • LED indicates when it is time to change cartridges
  • Temperature-compensated resistivity cell activates a red/green LED to indicate water quality meets requirements Resistivity meter operates on one 9V battery
