      Can I use this system with well water?

      If your home already has a whole-house filter, then the system can work perfectly with well water.

      Can the system reduce TDS?

The system can reduce harmful substances while keeping beneficial trace elements, though it is not designed for significant TDS removal. Please choose Waterdrop RO system if you’d like to reduce TDS.
