What is an Undersink Water Filter System?

Undersink water filters work on a very simple principle – they are placed under the sink (ie  a kitchen sink) and a diverter valve diverts the cold water from the Mains water pipes to the filter before it has reached the sink faucet. The water goes through the filter system and goes out through a separate faucet for filtered water that is placed on the sink or kitchen benchtop, somewhere near its standard faucet.
