To Virus aerosols address this issue, this study used a non-contact ultrasound transducer (NCUT) to generate shock waves in the air Virus inactivation at speciﬁc distances, input voltages, and exposure durations, targeting bacteriophage virus aerosols captured on Non-contact ultrasound transducer to H14 HEPA ﬁlters. Initially, a frequency of 27.56 kHz (50V) at 25-mm distance was used, which yielded an inactivation eﬃciency of up to 32.69 ± 12.10%. Other frequencies at shorter distances were investigated, where 29.10 kHz had the highest inactivation eﬃciency (up to 81.95 ± 9.79% at 8.5-mm distance and
