The nasal insert comprises a body having an inner surface which defines an air passageway surrounded by an outer surface of soft, flexible material. The nasal insert body can have a first portion and a second portion where the outer surface of said nasal insert body is configured to form a seal between the nasal insert body and the nasal cavity. The nasal insert body further includes any number sealing members extending from the outer surface of the nasal insert body, where the sealing members are adapted to the nasal cavity and can prevent air flow between the nasal insert body and the nasal cavity.
