How does under sink water filter work?
Conventional under sink filter: It receives water from the undersink cold water pipe and water flows from a flexible plastic tube to the water filter. And the water will be delivered to the user through the filter's own special faucet, installed on top of the sink. The system is under constant pressure so that when the user opens the filter's faucet, the sink water will flow through the filter and out the faucet.
Simple under sink filter: In this arrangement, the cold-water is diverted through the filter and filtered water is dispensed through the regular cold-water sink faucet. Besides, the hot water won’t be filtered.
