How regularly do need to change the eSpring® filter?

For maximum performance and quality, we recommend changing your eSpring filters every year, or every 5,000L of filtered water, whichever comes first.  The eSpring Electronic Module monitors the amount of water filtered and keeps track of how long the filter has been in service. When a year has passed, or as soon as the filter has reached 5,000L of water, the Electronic Module will alert you to replace the filter cartridge.
