Abstract: A device combining internal nasal filtration and internal nasal dilation operating synchronously provides air filtration by retaining particulate in a single piece foam nasal filter during inhalation through the nose. Internal nasal dilation is provided by the effect of a resilient member adhesively affixed to the nasal foam filter and which when bent from a planar surface applies outward biasing forces to each nostril so that breathing is facilitated.
