I installed a filter on my incoming “city water” line and I change it every 4 to 6 months. By then the filter is coated, mostly in mud, but I do see a difference in my bathtub as opposed to my neighbour’s. In addition, I use a Brita water jug for my drinking water, further eliminating contamination. (Yes, a bit zealous I will admit, but my drinking water tastes great and the ice cubes are crystal clear.)
