Home Water Filters: What exactly is a whole house water filter?
Whole house water filters deliver purified water throughout the entire home to every faucet. These large, high-capacity systems are installed on the main water line before the water heater to provide purified water to both hot and cold water lines. In the water industry, whole house filters are also known as point-of-entry (POE) filters because they treat water at the entry point going into the home. Smaller drinking water filters are known as Point-of-use (POU) because they can typically only treat water at a single station where the water is being used, like a kitchen counter.
Water softeners are a popular type of whole house filter, but they are actually just one subcategory under the whole house filtration branch which includes many types of specialized systems. We offer a large selection of both POE and POU water filters to treat every water need & concern.
