Embodiments of an adaptor for delivering diffused aromatic agents to a user of a CPAP machine may include a connector body, a diffuser pad disposed within the connector body, and at least one coupling mechanism on the connector body coupling the connector body within the air supply and positioning the diffuser pad within the airflow of a CPAP machine. The adaptor may be configured to couple directly to a CPAP mask. Similarly, the adaptor may be configured to be placed in the airflow between the CPAP air generator and the mask. The adaptor may be configured such that no modification of the existing CPAP hose, machine, or mask is required.
