  1. Wash your hands with soap and water; then remove filter from filter bag. NOTE: It is normal for a new filter to be wet when first opened. Filters are washed during manufacturing to prevent them from drying out
  2. Soak filter upright in cold water for 15 minutes
  3. Hand-wash pitcher/dispenser, lid and reservoir periodically with a mild detergent. Do not wash in dishwasher or use abrasive cleaners. Rinse well. For best results wipe with a soft sponge soaked in a solution of one teaspoon of vinegar in a cup of water
  4. Rinse filter under cold, running tap water for a few seconds
  5. Insert filter into reservoir by lining up groove in filter with notch in reservoir. Press firmly to ensure a tight seal
  6. Fill the reservoir with cold tap water. Discard your first two pitchers of filtered water (or first dispenser), or use this water for plants. It is normal for carbon dust to appear in your first fillings.
