• How often should I change my Culligan filter?

  Filter life varies by product and water usage. For pitcher filters, it is generally recommended to replace them every 20-40 gallons or when the TDS meter reads above '006'. For whole-house and under-sink systems, filters typically last 6 to 12 months.
