Did a search and I found this, not sure if it's the same as yours. https://www.shopnsave.com.my/products/korea-tong-yang-8900c-hot-cold-water-dispenser-water-purifier-best-water-purifier-water-dispensers Says that it's equipped with Alkaline Water System and also purifies the water. but honestly, boiled water is fine. don't think it's necessary for baby to drink alkaline water. Whether it's safe or not, best to check with your paediatrician.
i think depends on the filter it is using..cant tell from the picture..just give baby normal boiled water will do..
I think if the situation allow, just use boiled tap water. if is in the baby room in the mall, you cannot help it
I think normal boiled water is fine!
Boiled water is good.
