More Than Just Simple Brewing: The new dual brew and K-cup coffee capsule coffee makers don't just extract coffee through water flow; they also provide brewing pressure during the process, which is crucial for making excellent coffee. The special concave top cover of this coffee capsule for Ninja Dual Brew coffee makers perfectly fits the coffee machine's brewing head, ensuring no pressure leakage and delivering the best coffee experience! Continuous Improvement: We didn't just improve the coffee capsule's top cover; through extensive experiments, we found that the surface of the stainless steel filter also impacted the brewing experience. The current filter surface is perfectly balanced with the water flow release rate, significantly reducing coffee splashing and protecting your coffee maker.
