Abstract
(EN)

There is disclosed a fibre filter (10) for filtering a flow of gas therethrough, wherein the fibre filter (10) includes a fibre felt (30) including at least one fibre (20) that is matted together, wherein the at least one fibre (20) is manufactured from a plastics material that includes integrally therein a disinfecting agent that inhibits activity of microbes that are deposited on the at least one fibre (20) when the flow of gas occurs through the fibre filter (10). The fibre filter (10) is susceptible to being used in face masks (50) and air filters (150) of air-conditioning units, although many other uses are feasible.
