Understanding Whole House Filter Replacement

• Cloudy or discolored water: Indicates sediment buildup.
• Unpleasant taste or odor: Bacteria or chemical contaminants.
• Frequent appliance repairs: Scale buildup damages water heaters and pipes.

Case Study: A Massachusetts homeowner saved $2,000 on appliance repairs after replacing a 5-year-old filter.
