RO Membrane Identification Guide

Use the membrane or system label first. Similar nominal output wording does not establish membrane dimensions, connection configuration, chemistry, or system compatibility.

Identification checklist

  1. Record the complete printed membrane or system number.
  2. Record only documented membrane size and connection information.
  3. Check the applicable system manual before treating a replacement number as compatible.
  4. Keep stated package quantity separate from the membrane identity.
