How often the cartridge needs to be replaced is determined by how much water you put through the system and how hard the cartridge has to work to clean the water you put through it. Filtering your water through ZeroWater filters not only improves the taste of your tap water, it also prevents you from throwing plastic water bottles into the trash and clogging up landfills. Zero Technologies, LLC is proud to be the only major company that recycles gravity filter cartridges from U.S. customers. Contains 8 Cartridges.
