- The cartridge has a silver treated plastic housing with Ag+ Ionic Silver Technology. That inhibits microbial growth on the surface of the cartridge.
- Cartridge is refillable
- Easy replacement
- Odorless granules used
- The demineralization cartridge needs to be replaced every 2 - 3 months depending on the water hardness. If the water is very hard (= high amount of minerals), it may be necessary to replace the cartridge after 1 - 2 months.
