FILTER ELEMENT THAT CAN BE TREATED BY UV RADIATION, AND FILTER DEVICE, PROTECTIVE BREATHING MASK, AND PROTECTIVE BREATHING KIT COMPRISING SUCH A FILTER ELEMENT

摘要

A filter element (1) with a through-flow area for a fluid is proposed, which filter element (1) comprises a filter material (2). With a view to easier and improved antimicrobial treatment of the filter material (2), and with a view to improved deposition of microorganisms, this filter element (1) is configured such that the filter material (2) transmits and/or conducts UV radiation with a wavelength of ca. 450 nm or less. A filter device, a protective breathing mask and a protective breathing kit are also proposed on the basis of the filter element (1) according to the invention.
