Know before you buy

Yes, the remineralization stage is designed to restore essential minerals that are often stripped away during the reverse osmosis process. This balances the pH level, resulting in a crisp, refreshing taste that many users prefer over standard distilled or demineralized water.
The system includes a smart faucet that provides real-time monitoring of your filter life. It will alert you when a specific filter needs to be changed, taking the guesswork out of maintenance.
