Two solutions for doors
1. Filter roll for a hinged screen door
If your balcony door has a hinged screen door, the most practical solution is to replace its mesh with window filter. The door keeps opening and closing, and you keep walking through freely. If you are having a new screen door made, ask your screen maker to use window filter instead of mesh.

2. Hook-and-loop filter
On garden or balcony doors that are rarely used, you can fit the filter to the door frame with hook-and-loop tape. When you want to go through, just peel one edge of the filter off the tape. This method is not practical for doors you use often.
