NasalGuard+™ forms an invisible, electrostatically active barrier at the nasal entrance, the body’s primary air intake pathway. When applied around the nostrils, the charged gel layer interacts with airborne particles in the immediate breathing zone, attracting and binding fine particulate matter before it can be inhaled. By functioning directly at the point of entry rather than filtering ambient air, it provides localized microfiltration at the skin level without affecting normal breathing.
