Abstract : This paper deals the global existence and blow-up properties of the following non-Newton polytropic filtration system, $$u_t-\triangle_{m,p}u=u^{\alpha_1}\int_{\Omega}v^{\beta_1} (x,t)dx,\ \ v_t-\triangle_{n,q}v=v^{\alpha_2}\int_{\Omega}u^{\beta_2} (x,t)dx,$$ with homogeneous Dirichlet boundary condition. Under appropriate hypotheses, we prove that the solution either exists globally or blows up in finite time depends on the initial data and the relations of the parameters in the system.
