A:Answer Not from B.Buy or Bella - they don't sell replacement parts. You might find the answer from Bella here, but they don't give a suggested third-party replacement. They say it will last 3 to 6 months (what the heck) ... having used mine for a few weeks now, I'd say longer if you clean it carefully. The trick is to measure the filter, then ask an AI, which will find a replacement. FYI the Keurig filters don't fit. I haven't looked for one yet, but I think there should be several that will work.
