📌 Tips & User Experience

• Pre‑flush with 2–3 gallons to clear carbon dust and prevent cloudy water—per Reddit advice:

  "new filters need to be flushed with a few liters … cloudiness is expected but temporary." 

• Timely replacement matters: most users change every ~6 months. One shared:

  “I usually change it once every 6 months.” 

• No European chips required: GE MWF uses a standard threading, not RFID.
