Point of Entry (PoE)
Point-of-entry (POE) devices, which are installed on the water line as it enters the home and treat all the water in the building. They are installed at the main water line where water first enters the home.
This entry point is usually found in the garage, and POE systems are most commonly placed in front of the water heater to deliver purified hot and cold water to every tap in the home. This is why they are also known as “Whole House Water Filters” because treated water is delivered to all sinks, baths, showers, dishwashers, refrigerators, washing machines and toilets – basically covering the whole house.
