Multi-stage activated pressed carbon block replacement filter with UV-bulb. Lasts for 5,000 liters or one year, whichever comes first.

The eSpring™ Water Treatment System alerts you when it’s time to replace the filter and resets itself when installed.

Fits ONLY the eSpring™ Water Treatment System (100188, 100189 and  301904, 301905).

The eSpring™ Water Treatment System filter replaces the cartridge shipped with your original unit and is easily installed. The filter’s “smart-chip” monitors system performance and sends messages about function or replacement timing, which appear on the eSpring unit's lighted display.
