Tips for choosing safe drinking water in Thailand | A must-see guide for travelers and residents
In Thailand, tap water cannot be directly drunk, so deciding which water to choose is an important point for health management for tourists and residents alike. In this article, we will explain how to choose safe drinking water, compare major brands, and explain the features of the natural alkaline mineral water "Onsen Water 99."
Can you drink tap water in Thailand?
Tap water in Thailand is generally not suitable for drinking.
Although water purification is carried out in urban areas, there is a risk of recontamination due to aging piping equipment and unsanitary conditions in water storage tanks.
Local people rarely drink water directly; they generally use bottled water or water filtered through water purifiers.
Points to consider when choosing drinking water
-
Country of manufacture and water sampling area
Check if imported water meets the safety standards of the country of manufacture. For domestically produced water, the sanitary management system at the local factory is important. -
pH value and hardness
For people with sensitive stomachs and travelers, soft water or slightly alkaline water is considered easier to drink. -
Sealed condition and expiry date
Make sure the cap is tightly sealed and check the expiry date on the label. -
brand credibility
Brands with proven track records and quality certifications (ISO, Monde Selection, etc.) give you peace of mind.
