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

### ⭐⭐⭐⭐⭐ 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,
