NasalGuard Allergy Relief and Allergen Blocker Nasal Gel - Drug-Free and Proven Safe for Pollen Allergy Sufferers, Approved for Airplane Travel Over 150 Applications Per Tube (Cool Menthol, Pack of 2)

NasalGuard Airborne Particle Blocker is a clear gel, applied outside the nose, that uses electrostatic technology to reduce the inhalation of airborne particles. You won't see the particle blocking in action, but a pin-sized drop or two of NasalGuard restricts thousands of fine and ultrafine particles from entering your system for up to six hours by either attracting the particles to stick to the gel rather than being inhaled, or by repelling the particles away from your nose in the first place.
