## 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?**
A: TDS (Total Dissolved Solids) measures minerals, salts, and impurities in water. Zero TDS means the water is completely pure, leaving no spots or residue after drying - ideal for a spotless rinse.

### ⭐⭐⭐⭐⭐ excellent product
*by R***N on 31 May 2024*

this RO system is low cost and highly effective with the individual filters having good longevity, used for my carnivorous plants and fishtanks in an area with very hard and chemically treated water, produces about 2 TDS as final output

### ⭐⭐⭐⭐⭐ Blue resin life
*by B***B on 25 August 2023*

I brought this product. I am very happy with the result, but now the blue resin filter has turned a light brown color and the TDs are high. If any one knows how many liters of 0 tds water we can get in this resin filter before it turns to brown,
