Some of literature refers to point-of-entry (POE) and point-of-use (POU) treatment, what is the difference?
Point-of-entry (POE) devices are installed where the water supply enters the home. POE treatment devices consist of equipment applied to water entering the house or building for the purpose of reducing contaminants in all water distributed throughout the house or building. Point-of-use (POU) devices are installed at the tap and can be used to effectively remove contaminants from the water at the tap only. A POU water treatment device is a device or equipment used for the purpose of reducing contaminants in water at a single tap.
