Do you have to keep cremated ashes in an air tight container?

Cremated ashes do not necessarily need to be kept in an airtight container, but it is recommended to store them in a secure and respectful manner. Airtight containers can help protect the ashes from moisture and environmental elements, which can be beneficial if you plan to keep them for an extended period. Ultimately, the choice of container depends on personal preference and how you intend to memorialize or keep the ashes.
