Point of Use (PoU)
Point-of-use (POU) water treatment devices are designed to treat small amounts of drinking water for use in the home. These devices can sit on the counter, attach to the faucet, or be installed under the sink.
They are installed at a single water connection typically under the counter of a kitchen or bathroom sink. Most consumers install these systems to filter water that they will be using for drinking, cooking or bathing.These lower capacity, smaller systems will filter water at the actual “point” where it is being used.
