Abstract: The $\gamma _p$ property may be generalized by using filters on $\omega$ in a very natural way. We analyze the necessary requirements for a space $\mathcal{X}$ to have property $\gamma _{\mathcal{F}}$ for a filter $\mathcal{F}$ . We construct special filters for which $\mathbb{R}$ has the $\gamma _{\mathcal{F}}$ property, in particular a P-point and a Q-point.
