| 摘要 |
The present invention is a method for restricting the flow of airborne contaminants into a nasal passage. It involves creating an electrostatic field in an area near a human nasal passage. The electrostatic field may either repel or attract airborne contaminants or both. The method involves applying a topical application having a plurality of masses of one or more electrostatic materials, and a carrier having the plurality of masses dispersed therein. The masses have an average cross sectional area of about one square millimeter to about 50,000 square millimeters, and are of sufficient charge to create an electrostatic field which will prevent at least some airborne contaminants from passing into a human nasal passage. The topical application may be in the form of a solution, a semisolid, a solid, a spray solution or a vaporizable solution.
