Perfectly compatible with Ninja CFP301, CFP201 DualBrew Pro coffee maker pod adapter. Combine single-cup brewing with the coffee powder of your most satisfying grind quality to create a cup of your favorite coffee in 2 minutes. It's faster and easier to make a cup of coffee with this refillable coffee capsule than with a coffee basket. Fill the coffee powder to the correct position, start brewing, and you can get a cup of coffee in 1-2 minutes. Easy to clean after brewing (do not remove it immediately to avoid burns), just wash it under running water for a while. We have tested this cup hundreds of times. It works quietly and filters well, with no coffee residue at the bottom of the cup, and the coffee will not spill. It only takes 1-2 minutes to get a cup of coffee. These reusable K-Cup coffee filters are made of food-grade PP and food-grade 304 stainless steel (with finer mesh, more thorough filtering, and cleaner coffee). Compared to disposable coffee capsules, using these reusable K-Cups can save more money and reduce the disposal problem caused by disposable coffee bags (contributing to environmental protection).
