4. Look for Additional Features
Some under sink reverse osmosis systems come with additional features like remineralization or UV sterilization to enhance the quality of filtered water. While these features may not be necessary, they can be beneficial in certain situations. Consider if you need any extra features and choose a system accordingly.
5. Consider Maintenance and Replacement Costs
Reverse osmosis systems require regular maintenance and filter replacements to function effectively. Before buying a system, consider the cost and frequency of filter replacements as it can add up over time. Look for systems with affordable filter replacements and easy maintenance procedures.
