A bottle of mineral water may be purchased for the rest of your journey at the Mt. Everest Base Camp and three passes, but it costs more than it would in Kathmandu. Bring a 1- to 2-liter bottle and fill it up at each teahouse.
Similarly, I recommend using water purification techniques, such as utilizing a filter machine and ultraviolet rays or water purification medications. The water will become cleaner and safer to consume as a result. We do not advise using melted water for the drink.
