The present invention relates to a nasal plug for diverting airflow from a natural flow path in a person's nostril. In some circumstances, the airflow is channeled and directed to a specific location in a person's nasal or sinus cavity. The person may adjust and self-select a preferred airflow path by adjusting the nasal plug's location in the nostril, e.g., rotating the plugs. A kit may include two plugs, which may be used singly or in combination with each other and are independently adjustable/rotatable. A method for reducing nasal discomfort or improving nasal functions by diverting channeled airflow in a nostril is also disclosed.
