Die vorliegende Erfindung betrifft ein Filtermedium, eine Filteranordnung zur Filtration von Gas-Partikel-Systemen, die ein solches Filtermedium enthält, ein Verfahren zur Abreicherung von Pathogenen und/oder Allergenen aus der Luft und anderen Gasen mithilfe eines solchen Filtermediums und die Verwendung des Filtermediums zur Abreicherung von Pathogenen und/oder Allergenen aus der Luft und anderen Gasen. The present invention relates to a filter medium, a filter arrangement for the filtration of gas-particle systems comprising such a filter medium, a method for depleting pathogens and/or allergens from the air and other gases by means of such a filter medium, and the use of the filter medium for depleting pathogens and/or allergens from the air and other gases. The filter medium includes at least one acid-functionalized layer comprising at least one carrier material and at least one fruit acid having a pks1 value of 0 to 7. The at least one acid-functionalized layer is free of added C8 to C18 fatty acids and their esters and amides thereof. The at least one acid-functionalized layer contains the at least one fruit acid in an amount of 2 wt. % to 30 wt. %, based on the total weight of the at least one acid-functionalized layer.
