    * Frequency of Filter replacement depends on the quality of your water and consumption habits. It is recommended to test your water every 3 months to ensure your RO system purifies your water adequately to keep contaminants below 50 ppm (parts per million - milligrams over liters). Please use a TDS meter to know when you should replace your filters.
