1The Quick Answer
Tap water in South Korea is safe to drink and is among the cleanest in Asia, though many locals prefer bottled water by habit.
2What You Need to Know
South Korean municipal water systems meet strict quality standards and tap water is certified safe to drink in all major cities and tourist areas. Many Koreans choose to drink bottled or filtered water for taste preference rather than safety concerns, and water purifiers are common in homes.
