I was delighted to find out that these filters remove choline from the water.  I make water kefir and they die if there is any chlorine.  I tested the water with a chlorine strip and none was indicated.  Love it.  Now I don't have buy bottle water anymore, saving me money. These filters are also reasonable.  Thank you for the PureGreen WaterFilter.
