First Cartridge: 1 Micron Nano Zinc Polypropylene filter. The Nano Zinc filter removes bigger particles and dust along with inhibiting bacteria growth. This is a patented process and therefore the only one like it on the market.

Second Cartridge: Filter cartridge with Carbon and KDF (GAC 120g+ KDF - 20g)

Keep the casing and just change the cartridges! Simply unscrew the two parts of the filter casing and insert the cartridges - less plastic goes to the landfill. Note how the previous cartridges were installed and put the new ones in the same way. The shorter part of the filter casing installs towards the bottom. We recommend changing the cartridges every 5 – 7 months, more often than our previous water ionizer filter.
