Patrick Douglas –
Since only drinking from these two filters my family has had no stomach upsets due to bugs in our tank water. I like the way you can clean the ceramic filter for longer life between filter changes and that the carbon filter helps to remove pesticides etc from the sprays off the farms in our area.
