How long do water filter cartridges last? I bought a CrystalQuest 3 cylinder water filter for the home after their sales person told me that the pre-filter cartridge and the carbon block cartridge should be changed annually. But the 3rd cartridge is what he called a 6 stage multi-functional cartridge and will last 3 to 5 years. Their webpage specifies this, too.
