Why do my old coffee pods not work with the new Keurig?

Old coffee pods may not work with a new Keurig due to differences in design and compatibility standards. Newer models often have updated brewing systems or pod designs that require specific pod types. Additionally, older pods might be made for different brewing systems that do not fit or function properly in the new machine. Always check the compatibility of your coffee pods with your Keurig model to ensure proper use.
