Answer
Ion-Exchange Resins.
Explanation
## Step1: Understand the nature of the filtration process in treating hard water. ## Step2: An understanding of hard water and the substances that cause water hardness is crucial for this step. Hard water is water that has a high mineral content, with substances like calcium and magnesium being the major minerals contributing to hardness. When such 'hard' water passes through a water filter, these minerals are removed, rendering the water 'soft'.## Step3: One prevalent substance used within water filters to achieve this is Ion exchange resins. This substance works by exchanging the ions of the minerals causing hardness in the water (Calcium and Magnesium ions, etc.) with sodium ions. ## Step4: It's worth mentioning that other substances, such as activated carbon and mechanical filters, may present in the water filter, but those do not specifically target the removal of hardness.### So, the answer should indicate the major component in the water filter that goes into action to deflate hardness in the water is Ion-Exchange Resins.
