Monitoring of the filter cartridge

The filter cartridge is rated for 10,000 gallons (38,750 litres), approximately 6 months for 2 people, under normal conditions. The internal measuring device will keep track of the amount of water that is processed through the filter. To activate this system, the battery included with the filter must be inserted into the LED cap. The LED light will blink ONLY when the filter has water flowing through it. The LED will blink green through the 1st 8,000 gallons. After 8,000 gallons the light will blink yellow, indicating that the maximum capacity of the filter cartridge is approaching. At 10,000 gallons the light will blink red indicating that the useful life of the cartridge has been reached.

To change the filter cartridge:

  1. Replace the battery and push the reset button.
  2. Remove the old cartridge by turning the bottom cap counter clockwise while firmly gripping the housing. Do not remove the showerhead.
  3. Gently twist the cartridge and pull it from the bottom cap.
  4. Push the new cartridge into the bottom of the cap until sealed. Replace the assembled cartridge onto the housing using a clockwise motion, while also firmly holding the housing in place.

A new battery will reset the flow count and the light will begin to blink green the next time that the shower filter is used.
