POE vs. POU Water Filtration Differences

POE vs. POU Water Filtration Differences

There are some very distinct differences between point-of-use (POU) and point-of-entry (POE) water treatment products. When looking to treat your own water at home, understanding the differences between point-of-use (POU) or point-of-entry (POE) systems can help you find the most efficient set up to meet your needs.  To keep the explanation simple POU: Point-of-use treatment systems often installed right at the tap versus POE: Point-of-entry treatment systems are installed on the main water supply line.

For POE systems, pressure drop can be a main concern since most of the household plumbing is downstream of the system.  Additionally, POE systems may be treating water for a longer period of uninterrupted flow when the washing machine or showers are running. POU systems, however, are mostly used for relatively short periods of flow as consumers fill glasses of water, and they have longer stagnation periods when they are not used. POE systems typically have much higher capacities because they are treating many times more water than POU systems.

Whether you need to disinfect your water, reduce hardness, or improve its taste, both styles of devices give you a range of options for putting control of your water quality back in your hands.
