good filters, a week for the first filter, water test at 8.7 so that helps. Note: The water tastes great, take some time to read the filter installation instructions properly. First, immerse the filter to the brim in a large glass of tap water and allow the filter time to remove any air bubbles. This will help remove loose carbon particles from the filter. You will notice particles. Rinse again in the same way and you will notice very small particles. Second, screw the filter into the jug and add tap water. Run it through and drain the water. Repeat the process again and drain the water from the jug. Rinse the jug and start the process for ready-to-use water. It's worth the time and energy for great water.
