A:AnswerTalking to myself here. Bella doesn't know what third party filter to get. The Keurig one's don't fit. The trick: measure the filter and ask an AI for a replacement. (I haven't looked yet.)
A:AnswerHi, thank you for reaching out. The coffee temperature will slightly different based on the cup sizes, the larger the cup size it will hotter.
For 6oz setting the coffee temperature should be higher than 78C.
One thing that would affect the temperature is the cup. Large ceramic cups will extract heat and will make the coffee in the cup feel cooler.
A:AnswerNot 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.
