Used around the home for well water, these 1 micron and 5 micron versions make a world of difference. I have 2 in series what is the difference in water quality. I take them out after a month, wash them with a pressure washer and get them for another 30 days. I do this a maximum of 3 times and then swap. Using 2 of the 1 micron version reduces the available water pressure/flow enough to be noticeable, but not enough to be a problem.
