A whole-house water filtration system is often considered superior to portable units for several reasons. Whole-house systems treat water at the point of entry into your home, ensuring that all faucets, showers, appliances, and even outdoor water sources receive filtered water. This provides a comprehensive solution for your entire household. They are designed to handle a wide range of contaminants, including sediments, chlorine, heavy metals, pesticides, and more. They often incorporate multiple stages of filtration. Whole-house systems also allow for customization based on the specific water quality issues in your area, ensuring that the filtration system is tailored to your needs. We have a whole-house system that we work with exclusively. We have not found any better system.
