In the first study, 76 Covid-negative volunteers were recruited. The exhaled aerosol was measured prior to the nasal intervention. After they received FEND, the intervention suppressed 78% of exhaled aerosols in this group.

The second study covered a family of four in quarantine with one Covid-positive mother. After the intervention, her levels decreased to average baseline levels for a Covid-negative patient, for several hours.

The third study compared use of FEND to surgical mask use in 12 participants. The masks reduced overall exhaled particles by around 34%, while FEND reduced overall them by 46%.
