回复：谢谢。您的建议是自己装，然后让房东报销费用。而不是自己把费用从房租里扣出来。

 home depot in my location do not sell现成的纱窗，because make 纱窗 is so easy for most people. easier than fix a flat tire of bicycle. a little bit difficult than wrap a a gift box. 
First, you need to decide the screen to be outside of your current window or insides --- depend on the open direction of you current window, then measure the inner-size of window frame. 
If you do not have a saw, ask  home depot staff to cut screen-frames for you when you buy them.
