This paper deals with the blow-up properties of the non-Newtonian polytropic filtration equation
$u_t - div(|∇u^m|^{p-2} ∇u^m) = f(u)$
with homogeneous Dirichlet boundary conditions. The blow-up conditions, upper and lower bounds of the blow-up time, and the blow-up rate are established by using the energy method and differential inequality techniques.
