In total the H1 and ZEUS experiments collected an integrated luminosity of about 1 fb$^{-1}$. Recent results of model independent searches for new physics from both experiments are presented. Specifically, studies of the events with an isolated lepton and missing transverse momentum and multi-lepton topologies, where H1 and ZEUS data are combined, and a general signature based search are discussed.6 pages, 5 figures; To appear in the proceedings of the XLIIIth Rencontres de Moriond on Electroweak Interactions and Unified Theories, La Thuile, Aosta Valley (Italy), March 1-8, 2008High Energy Physics - Experimenttext
