abstract = "Filter testing methods are described by various industrial standards. A broad range of different parameters, which can be evaluated, are stated there. Nevertheless, many filter testing methods are complicated and time consuming. Two novel filter testing methods are developed in corporation with the company ICE Str{\"o}mungsforschung GmbH. The first method, called translucency examination, makes it possible to find out a direct correlation between the pressure drop of filter samples and their local grey values, determined by photography. Furthermore, the deviation of the experimental results diminishes because representative samples can be selected. This yields in a reduced working time as fewer samples are needed to get results with an equally sufficient statistical accuracy. The acquisition costs for the translucency examination are relatively low, the handling is simple and it can be integrated into every standardized laboratory procedure without any problems. The second innovative filter testing method is capable of determining the particle penetration depth in filter media with the help of fluorescence macrophotography.",
