IDENTIFY YOUR RO MEMBRANE: The RO Membrane is the long horizontal filter on top of the system. RO Membranes are rated to filter to a specific amount of water measured in gallons per day (GPD). To identify the gallon per day (GPD) rating on your current RO membrane, disconnect the single tube connected to the membrane housing cap. Unscrew the membrane housing cap and remove the membrane from the housing. Look for a label with the gallon per day (GPD) rating on it. Select a membrane from the options below that most closely matches the gallon per day (GPD) rating on your current membrane
