POU pertains to low-capacity water filters which purify water only when it is about to be used. They are small, cheap, and easy to install but have lifespans of only three to six months. The Reverse Osmosis system, which promises 99 percent purification via hyper-filtration membrane technology, is a type of POE system designed to produce the highest quality drinking water. This is the method that small-time water purification stores usually employ.
