FILTERS AND FILTER CHANGE INDICATOR
FILTERS
The filters are critical to the performance of the Circle Reverse Osmosis Water Filtration system, and
it is important to replace all of the filters on a regular basis. If any of the filters are overused beyond
the recommended service life, the performance of the water filtration device can deteriorate. Do not
miss the filter replacement cycle or use non-compatible filters as this can affect system performance
or damage the unit.

replacement filters.
FILTER CHANGE INDICATOR
The LED filter change indicator in the faucet works by tracking both time and water flow from the
Circle RO system. When 6 months time or 475 gallons of water has been filtered through the system
(whichever comes first), the LED will flash red when dispensing water instead of flashing blue.
When the faucet LED indicator begins to flash red, it's now time to change the filters and reset the
faucet indicator by replacing the battery.
Note: a new battery is always included with the RF-20 filter replacement set.
