How to confirm the match

  • Confirm the system label says RO-90, including every suffix.
  • Compare the installed cartridge or membrane part number.
  • Check the stage count and membrane capacity where applicable.
  • Follow the manufacturer’s replacement schedule for each stage.

Do not choose a replacement by cartridge appearance alone. Similar housings can use different connections, capacities, or stage combinations.
