- After irradiating Human Respiratory Syncytial Virus (HRSV), there was an >99.98% kill rate. This is equal to log3.75.
- After irradiating Rotavirus A, there was an >99.68% kill rate. This is equal to log2.50.
Anti-Bacterial & Anti-Fungal Test
- At 50cm (or 1.64 feet) in distance there was a 99.9% kill rate of E. Coli after 8 hours
