A water filter under sink system is a type of water filtration system that is installed under the sink to purify water. It works by filtering the water as it passes through various stages of filtration, such as sediment filters, activated carbon filters, and reverse osmosis membranes.
The system is typically installed under the sink and includes a dedicated faucet that dispenses purified water. The water is first passed through a sediment filter that removes larger particles like dirt and sand. Next, the water is passed through an activated carbon filter that removes chlorine, volatile organic compounds (VOCs), and other impurities that can affect the taste and odor of the water.
To install an undersink RO water purifier, a small hole must be drilled into the sink or countertop to accommodate the faucet that dispenses the purified water. The unit also requires access to a power source and a drain.
Some water filter under sink systems also include a reverse osmosis (RO) membrane, which is a semi-permeable membrane that removes dissolved solids and contaminants, such as lead, arsenic, and fluoride. The purified water is then stored in a tank until it is needed.
Water filter under sink systems are popular because they are out of sight and do not take up valuable counter space. They are also more effective than traditional water filters, as they can remove a wider range of contaminants from the water.
Regular maintenance of the system is important to ensure that it continues to function properly. This may include replacing the pre-filters and the RO membrane as needed, and sanitizing the system periodically to prevent the buildup of bacteria or other contaminants.
