The cheapest brands are Bongpyeong Spring Water and Blue from E-mart. These bottles go for about 470 won per 2 liter. Many different water brands get water from the same source, and sell the ‘same’ water under different prices and labels.
Some of the most popular brands include Jeju Samdasoo, which is sourced from the pristine Jeju Island and is known for its refreshing taste and mineral content. Another popular brand is Bongpyeong, which is sourced from the foothills of Mount Seorak and is known for its clean, pure taste.
