We consider properties of state filters of state residuated lattices and prove that for every state filter $F$ of a state residuated lattice $X$: \begin{itemize} \item[(1)] $F$ is obstinate $\Leftrightarrow$ $L/F \cong\{0,1\}$; \item[(2)] $F$ is primary $\Leftrightarrow$ $L/F$ is a state local residuated lattice; \end{itemize} and that every g-state residuated lattice $X$ is a subdirect product of $\{X/P_{\lambda} \}$, where $P_{\lambda}$ is a prime state filter of $X$. Moreover, we show that the quotient MTL-algebra $X/P$ of a state residuated lattice $X$ by a state prime filter $P$ is not always totally ordered, although the quotient MTL-algebra by a prime filter is totally ordered.
