Soft Pods are specifically designed for compatibility with certain single cup pod brewers. The difference between standard pods and Soft Pods is that the soft pods are lighter in weight (about 7 grams) and are obviously soft, meaning that they are loose and have more room in the pod, they are not firm like most coffee pods. This gives more flexibility when using in brewers with tight clearance like the Senseo and Hamilton Beach brewers and will result in a better extraction in these brewers. See the bottom of this page for a list of brewers that require soft pods..
