Rinse: There may be distribution of dust through air vents. Consider HEPA filters for the heating system. Rinse with nasal saline several times daily until clear. If other symptoms develop, please see your PCP. Avoid any exposure to dust, pollen, pets and other allergens. Avoid smoke exposure, including secondary smoke.
