replacement lters.
The lters are critical to the performance of the Circle Reverse Osmosis Water Filtration system, and
it is important to replace all of the lters on a regular basis. If any of the lters are overused beyond
the recommended service life, the performance of the water ltration device can deteriorate. Do not
miss the lter replacement cycle or use non-compatible lters as this can aect system performance
or damage the unit.
The LED lter change indicator in the faucet works by tracking both time and water ow from the
Circle RO system. When 6 months time or 475 gallons of water has been ltered through the system
(whichever comes rst), the LED will ash red when dispensing water instead of ashing blue.
When the faucet LED indicator begins to ash red, it’s now time to change the lters and reset the
faucet indicator by replacing the battery.
Note: a new battery is always included with the RF-20 lter replacement set.

The lter replacement cycle may be increased for areas with poor water quality or
greater use.
The period for the lter exchange is based on an average production of 2.6
gallons of drinking water per day.
