## Questions & Answers

**Q: How often should I replace the filters?**
A: Sediment and carbon filters typically last 3-6 months. RO membranes last 1-2 years depending on usage. DI resin should be replaced when it changes color.

**Q: Can I use RO Buddie for drinking water?**
A: No

**Q: What is TDS, and why is zero TDS important?**
