In this work we study the dynamics of the maximum extractable entanglement for a system composed of two qubits interacting either with two independent thermal baths, a common thermal bath or a common squeezed bath. The states with maximum entanglement are found by applying filtering operations which transform each state to a state in Bell diagonal form. We observe a revival of the maximum extractable entanglement for common baths. It is also shown that for some particular states in two independent baths at zero temperature, one can partially recover the initial entanglement at any time.
