We define filter quotients of $(\infty ,1)$-categories and prove that filter quotients preserve the structure of an elementary $(\infty ,1)$-topos and in particular lift the filter quotient of the underlying elementary topos. We then specialize to the case of filter products of $(\infty ,1)$-categories and prove a characterization theorem for equivalences in a filter product.

Then we use filter products to construct a large class of elementary $(\infty ,1)$-toposes that are not Grothendieck $(\infty ,1)$-toposes. Moreover, we give one detailed example for the interested reader who would like to see how we can construct such an $(\infty ,1)$-category, but would prefer to avoid the technicalities regarding filters.

我们定义的过滤商 $（\infty ，\mathrm{1个}）$类别并证明过滤商保留了基本元素的结构 $（\infty ，\mathrm{1个}）$-topos，特别是提升基础基本topos的过滤商。然后，我们专门研究以下情况的过滤器产品$（\infty ，\mathrm{1个}）$类别并证明过滤器产品中的等价特征定理。

然后，我们使用过滤器产品来构造一大类基础 $（\infty ，\mathrm{1个}）$-格洛腾迪克以外的地方 $（\infty ，\mathrm{1个}）$-姿势 此外，我们为感兴趣的读者提供了一个详细的示例，希望了解我们如何构造这样一个$（\infty ，\mathrm{1个}）$-类别，但希望避免使用有关过滤器的技术。
