Each cartridge is rated for approximately 2,000 gallons, typically 6 to 12 months. Actual life depends on feed water quality, system configuration and usage. Replace it sooner if taste, odor or flow changes.
Use it only in the Crystal Quest faucet mount housing, in either the chrome or white finish. Flush a new cartridge with cold water for 5 to 10 minutes before first use, then run water for 2 to 3 seconds before each use. Media fines in a new cartridge are not harmful but should be flushed out first.
