nanoe™ X is Effective in Inhibiting Adhered Novel Coronavirus (SARS-CoV-2)

A global contract research organization Texcell has verified the inhibitory effect of the nanoe™ X technology, with known benefits of hydroxyl radicals on the adhered novel coronavirus (SARS-CoV-2). Over 91.4% of adhered novel coronavirus (SARS-CoV-2) activity was inhibited within 8 hours in a 6.7m³ test space.
Notes: (1) The virus infectious titer was measured and used to calculate the inhibition rate. (2) This verification was designed to generate basic research data on the effects of nanoe™ X on the adhered novel coronavirus in laboratory conditions. Actual effects will vary depending on the environment and usage of the product.
