This keg can be customized for water purification applications. It is designed to hold up to 5 kg of 100% natural coconut shell activated charcoal (filter material not included). With high porosity, the charcoal effectively removes impurities, while the extended contact time between water and charcoal improves purification performance.

Available in 1.75-gallon, 2.5-gallon, 3-gallon, and 5-gallon capacities, this versatile vessel is suitable for water purification brands, home water filter manufacturers, OEM/ODM projects, household water treatment systems, commercial filtration setups, and various customized clean-water solutions.
