How does under sink water filter with a faucet work
The cold water (Contaminated water) from point A sends water to the filter at point B where the filter is mounted at the bottom of the sink.
Then delivers clean water to the user through a particular faucet installed at the top of the sink at point C
The process is under high pressure when you open the filter faucet mounted on top of the sink water flows from the entry point to the filter then out the filter faucet.
Some under sink water filters use the reverse osmosis method to treat your water while others use a multi-stage filtration process.
Advantages of Under sink water filter with faucet

- Multi-stage filtration process removes different impurities present in water thus giving safe water for drinking
- Saves time since you get filtered water just by turning on the filter faucet
- Compared to another filter like pitchers filters it filters 1,000 gallon of water where else pitches filters 20 gallons.
- Don’t take counter top space of your sink.
- It does not waste any water like inline under sink water filter and under sink reverse osmosis system
