A method for improving flame resistance in filter systems in which an air flow charged with flammable aerosols is fed to a filter. The filter prevents a least a substantial portion of the flammable aerosol from reaching the air flow exiting the filter. A granular flame retardant material is fed to the air flow containing the flammable aerosols prior to the air flow containing the flammable aerosols being fed to the filter. The flame retardant has porous mineral granuales as an essential component. |
