abstract |
The invention provides a device adapted for the inactivation of a virus in a fluid, the fluid being either a liquid or air containing breath moisture, comprising a housing delimiting a fluid passageway, the passageway being provided with a virus-inactivating material that has a copper (I) species and a copper (II) species as part of copper oxide compounds that release a combination of Cu + and Cu ++ copper ions into the fluid when exposed to the fluid that passes through the passageway for the inactivation of viruses passing therethrough. |
