FellowAiden Precision Coffee Maker Paper Filters - Flat Bottom Designed for Aiden’s Batch Brew Basket - 50 Disposable Filters

These filters are high quality and fits really well. Compared to other brands, they find the right balance between being enough sturdy to hold their shape and work well for coffee. Unfortunately, I deduct one star because they are a tad too low for the Aiden. When you do more than a liter of coffee with fresh beans, the bloom cycle can cause the grinds to spill over the sides.

Fellow has made it impossible to replace these filters. On Amazon these filters are now unavailable, and when you go to Fellow they charge you $7 to ship paper. Although their coffee maker is works well, the accessories that you need to make the coffee are difficult. If you try to contact customer service they will tell you that you can use any 8-12 cup filter, which is not true because the typical 8-12 cup filter is not tall enough.
