The RDWS-PH-MAX Series low pH water filters are designed to address the issues associated with acidic water, particularly in well water sources. Acidic water can be problematic because it tends to corrode plumbing systems, especially copper pipes, leading to potential damage and staining. The RDWS-PH-MAX filters help neutralize this acidity through the use of calcite, a naturally occurring mineral.

Here's a breakdown of how these filters work:
  1. Neutralizing Acidic Water: The filter uses calcite, which is a form of calcium carbonate. As water flows through the filter, calcite dissolves into the water, raising the pH level and neutralizing its acidity.
  2. Preventing Corrosion: By increasing the water's pH and adding beneficial minerals, these filters help reduce the risk of corrosion in plumbing systems. This is particularly important for copper pipes, which are vulnerable to corrosion from acidic water.
  3. Beneficial Minerals: The addition of calcium from calcite not only helps to balance the water's pH but also enhances the water's overall mineral content, which can be beneficial for health.
  4. Integration with Other Filters: For optimal performance, calcite filters should be installed after sediment filters to ensure that any particulate matter does not clog the calcite. Additionally, they can be placed before iron removal filters in a multi-stage filtration system to increase the efficiency of removing iron and other impurities.

​In summary, the RDWS-PH-MAX Series filters are a practical solution for managing low pH water, protecting plumbing systems, and improving water quality by balancing pH and adding essential minerals.
