You have to replace the filter every couple of months. The pitchers are cheap, and the filters are usually under $10. You have to remember to replace the filters when needed, which can be inconvenient.

Read the package carefully to determine what the filter doesn’t remove. It varies by model. Most carbon filters will not remove fluoride. These systems can be more expensive at first, but you only have to replace the filters once or twice each year.

These systems are relatively cheap and need their filters changed periodically. The schedule of filter changes depends on the model.

Distillation takes out all the beneficial minerals. You can buy a home distillation system that can remove almost all contaminants.

This process eliminates bacteria, nitrates, asbestos, and heavy metals. This process leaves in chlorine but removes all beneficial minerals like fluoride. Check the label to see exactly what the model removes. These systems are expensive, ranging from $500 to $1000, though the overall filtering cost may be cheaper in the long run than other systems. You should replace the filter once each year.

You can also try calling the local health department.

You can ask about the source of the water. Groundwater is generally cleaner due to the natural filtering from the soil. Surface water has a tendency to pick up more pollutants. If they tell you that the EPA has tested the water, ask for the results. You can also ask for a copy of the test results since by law they have to provide you with information about water contaminants.
