Aqualine Water Filter

The Aqualine water filter (equivalent to similar systems like Nikken or Keosan) is a gravity-fed water purification and mineralization system. It is designed to mimic the natural filtration process of water passing through soil layers. The system typically consists of a ceramic pre-filter, a multi-stage filter cartridge containing activated carbon and mineral stones, and a final reservoir with additional mineral rocks to enrich the water.

While popular in Europe and Australia, these systems are primarily manufactured in South Korea, a country renowned for advanced water filtration technology. The brand focuses on providing alkaline and mineralized water for home use without the need for electricity or direct plumbing. Ownership is usually held by regional distributors that specialize in health and wellness appliances.
