For a non-isolated point $x$ of a topological space $X$ the network character$nw_\chi(x)$ is the smallest cardinality of a family of infinite subsets of $X$such that each neighborhood $O(x)$ of $x$ contains a set from the family. Weprove that (1) each infinite compact Hausdorff space $X$ contains anon-isolated point $x$ with $nw_\chi(x)=\aleph_0$; (2) for each point $x\in X$with countable character there is an injective sequence in $X$ that$\F$-converges to $x$ for some meager filter $\F$ on $\omega$; (3) if afunctionally Hausdorff space $X$ contains an $\F$-convergent injective sequencefor some meager filter $\F$, then for every $T_1$-space $Y$ that contains twonon-empty open sets with disjoint closures, the function space $C_p(X,Y)$ ismeager. Also we investigate properties of filters $\F$ admitting an injective$\F$-convergent sequence in $\beta\omega$.
