This disclosure relates to a system and method for disinfecting a conduit, such as a conduit for use in a continuous positive airway pressure (CPAP) system. An example system according to this disclosure includes a sheath a probe magnetically suspended within the sheath. The probe includes an ultraviolet light source configured to emit ultraviolet light. Further, the probe is spaced-apart from an inner dimension of the sheath to allow a conduit to pass between the probe and the sheath.
