Point-of-use (POU) systems treat the water where we drink or use water such as kitchen faucet, shower head, etc. and include water pitchers, faucet filters and under-sink reverse osmosis (RO) systems. Whole-house/point-of-entry (POE) systems treat the water as it enters a residence. They are usually installed near the water meter (municipal) or pressurized storage tank (well water). Whole-house treatment systems include UV microbiological systems, water softeners or whole-house filters for chlorine, taste, odor and particulates. POU and POE treatment devices rely on many of the same treatment technologies that have been used in water treatment plants. However, while water treatment plants treat all water distributed to consumers to the same level, POU and POE treatment devices are designed to treat only a portion of the total flow. POU devices treat only the water intended for direct consumption (drinking and cooking), typically at a single tap or limited number of taps, while POE treatment devices are typically installed to treat all water entering a single home, business, school, or facility.
POE systems offer high-capacity filtration and can treat up to several thousand gallons of water per day. They are normally larger in size with smaller mountable units, measuring from 20”H x 4.5D”, to taller freestanding mineral tank systems that stand up to 65 inches or more in height. These versatile units can use a variety of different filter cartridges and media beds to practically remove any type of water contamination. The higher capacity & volume of POE systems also make them the most durable and maintenance free solutions, with some larger units only requiring filter replacements every 5-7 years. POU systems are installed at a single water connection typically under the counter of a kitchen or bathroom sink. These lower capacity, smaller systems will filter water at the actual “point” where it is being used. While POU purified water can be distributed to more than one outlet, the low volume production (20-100 GPD) makes it best suited for light use applications. Depending on the size of the unit, some POU filters will last only 3-6 months with others lasting up to 1 year or more. Examples of POU systems include under-counter and countertop reverse osmosis (RO) systems as well as basic sediment and carbon faucet filters.
