A device for mitigating the replication of pathogens at a user's nose. The device may include architecture and techniques for both introducing heat to nostril locations while at the same time, mitigating the temperature level at the nose for sake of long-term user comfort. In one embodiment this may be achieved through a device that utilizes a heat-generating substance layer in combination with a temperature modulating substance layer that employs a phase change material to attain the temperature modulation. In this type of construction, the phase change material may also be employed to take on and store heat that is later released to extend the effective life of the device as a pathogen mitigator. Alternative architecture and techniques may also be employed.
