When to Change Filters or the RO Membrane

Prefilter(s) should be changed at least once every 12 months. The postfilter should be
changed every 12 to 36 months. The RO membrane should be changed when it fails to provide
sufficient water for nomal use, or when the RO water quality drops to an unacceptable level.
Several considerations need to be made regarding what is “acceptable” RO water quality.

Factors such as nitrate or arsenic removal, feed water Total Dissolved Solids (TDS), and
membrane age need to be taken into account. Generally speaking, RO water may be considered
acceptable if the TDS is below 70 ppm (parts per million), the percent rejection is above 70%, and
specific contaminate reduction is acceptable. Your local Water Factory Systems dealer is an excellent
source of information regarding local water quality issues. If you do not know a dealer - visit the CUNO
website at www.waterfactorysystems.com or call CUNO Customer Service at 1-800-733-1199.

Your local dealer can test your water quality. An optional water quality monitor is available
from your dealer. Local water conditions are the primary factor influencing acceptable RO membrane
life. Generally speaking, the RO membrane should last 2 to 4 years.
