Some contaminants that are most common include lead, DBP, parasites, arsenic, aluminium. The effects on our health can range from gastrointestinal diseases to cancer in cases of prolonged exposure.

A point of use (POU) system is used to filter water coming out from a single faucet, for example the kitchen sink faucet. A counter top water filter is one example of a POU device. The second style is a point of entry (POE) system, which treats water before it enters your home, thus water that comes out from every single faucet will be filtered water.
