I just replaced my two inline water filters. The first filter is a 1 micron particulate filter and it has been replaced 4 times this summer due to it doing it's job (county water). The second filter is a 1 micron carbon filter. This is the first time it has been replaced this year, but it was due based on water flow after after the primary was replaced.
All is good again.
