Interfering ions and the recommended flow rates must be specifically accounted for when sizing these cartridge.
Note: Performance of the filter will be degraded by flow rates in excess of 0.25 gpm, high pH or high bicarbonate supply water. If the supply water tests above 100 ppm of bicarbonate, the fluoride reduction will be degraded to less than 50%; if the supply is over 200 ppm, the reduction efficiency is less than 75%. |
