Embodiments of the invention are directed to nasal stents incorporating a filter and methods of use thereof. In one embodiment, a nasal stent has a stent body having a lumen with the same inner diameter (ID) along the length thereof. In an alternative embodiment, the nasal stent has a stent body having a lumen with a decreasing ID along the length thereof. In any embodiment, the stent is capable of having a compressed configuration and an expanded configuration. The nasal stent may further include a tubular insert housing a retaining mechanism to retain a filter at a proximal end thereof. A support may further fix the filter at a proximal end thereof. When inserted within a nostril of a person, the filter may function to filter particulates from the air when a person breathes in.
