Water filtration and water softening for well water systems is different. Not that one is better (and yes there are two sides) but it is different.

Municipal water sources add chlorine (or chloramines) to treat and dissenfect the water that you drink.  Depending on where you live, the chlorine level can be higher than that in a swimming pool. In other locales it is almost non-existent.  Well water, however; is different.  The water source comes from a well that is tapped into a water table.  Sometimes it is at a depth of 60 feet, other times; it can be twice that depth.  As a result, there tends to be more sediment found in the water, and; in some cases; more calcium and residue due to natural erosion.

Since well water typically is not chlorinated, a carbon block filtration medium may not be the best filtration solutoin. A better solution is a cartidge that has a high flow
