We present a ZFC construction of a non-meager filter which fails to be countable dense homogeneous. This answers a question of Hernández-Gutiérrez and Hrušák. The method of the proof also allows us to obtain for any $n\in \omega \cup \{\infty \}$ an $n$-dimensional metrizable Baire topological group which is strongly locally homogeneous but not countable dense homogeneous.
