The large scale structure of the Universe is organized in a web-like structure known as the Cosmic Web. Inter-connected structures are organized hierarchically,with knots, filaments, sheets and voids. Although it is difficult to detect X-ray emission from the hot gas within filaments,the sensitivity of eROSITA will allow to perform such detection by the stacking of regions connecting neighboring clusters. In this sense, the first eROSITA all-sky-survey (eRASS1) will provide a large sample of close cluster pairs with exceptional data statistic to search for X-ray emission from cosmic filaments. We will perform an analysis of this sample in order to study physical and chemical properties of the filamentary structures.
