The filtering distribution is that of $$X_t \vert Y_1=y^*_1,\dots,Y_t=y^*_t,$$ where \(X_t\), \(Y_t\) are the latent state and observable processes, respectively, and \(y^*_t\) is the data, at time \(t\).
The filtering mean is therefore the expectation of this distribution $$E[X_t \vert Y_1=y^*_1,\dots,Y_t=y^*_t].$$
