How long will my AP430SS filter last before I need to replace it?

This same information applies to many of the filters we carry, however, the life expectancy of the AP430SS filter (AP431) depends on the hardness of the water, and also the water usage.

The harder the incoming water is, the faster the phosphates inside the filter will dissolve.

The more people in the home, the more water that will be used. So a family of 6 will use up the filter faster than a family of 3, when the water hardness is the same.
