These filters feature a 5-layer filtration system, including coarse and fine particle filters, ion-exchange resin for heavy metal reduction, and an activated carbon filter to improve taste and remove odors. They are compatible with all CASO Turbo hot water dispensers with a filter insert and other water filter systems, offering perfect sealing with a silicone ring. Each filter can be used for approximately 4-6 weeks or 160 litres.
