I prefer Ipoh. Natural water and pure water are two different concepts Ipoh is pure water and Nongfu Spring is natural water. However, Ipoh's production technology and implementation standards are very strict, so the taste of pure water is good, and Nongfu Spring is also good, with a little sweetness. I prefer to drink Nongfu Spring. Of course, Ipoh is the best choice to quench your thirst. So which kind of water is better to drink actually has its own characteristics, or depends on personal preferences.
