## Questions & Answers

**Q: Compatible Model**
A: T1 / T1 Lite / E1

**Q: Why should we design a separate alkaline mineral boost carafe for the water purifier?**
A: Yes. This design is intended to enable you to assess the quality of pure water through the TDS value on LED. Also, the standalone mineral filter paired with a glass water carafe, provides the option of pure water and alkaline mineral boost water.

**Q: Why should mineral filter be soaked before first use?**
A: When the mineral filter is dry, it can impede the flow of pure water and cause water overflowing. Before the first use, soak it for 8-10 hour in advance to ensure optimal flow. Additionally, use the Half/Full button to dispense mineral water.

**Q: How often do I need to replace the mineral filter?**
A: The lifespan of the mineral filter is 3-6 months. If used frequently, it is generally recommended to replace it every 3-4 months. The mineral filter set comes in a pack of 3, please feel free to use it.
