Abstract

To improve hygiene in the COVID-19 pandemic, we evaluated the intranasal delivery of calcium-enriched saline to suppress breath particles in practical settings reflecting essential worker hygiene, quarantine hygiene, and back-to-school hygiene. In studies with 92 men, women, and children, we observed that nasal salt aerosols lowered exhaled particles for the group by around 75%, and outperformed surgical face masks in the clearing of sub-micron particles.
