The Claim

NONS reduces respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and human parainfluenza virus type 3 (HPIV-3) infectivity by over 2.8-3.8 log10 (>99.85-99.98%) within 2 minutes in vitro, achieving complete inactivation to detection limits.

In plain English

This says that a substance called NONS can quickly kill certain viruses that cause respiratory infections, making them almost completely harmless in lab tests.
