Filter quotients and non-presentable (∞,1)-toposes

We define filter quotients of $(\infty,1)$-categories and prove that preserve the structure an elementary $(\infty,1)$-topos in particular lift quotient underlying topos. then specialize to case products a characterization theorem for equivalences product. Then we use construct large class $(\infty,1)$-toposes are not Grothendieck $(\infty,1)$-toposes. Moreover, give one detailed example interested reader who would like see how can such $(\infty,1)$-category, but prefer avoid technicalities regarding filters.
