Short answer
The balcony door is the biggest “window” in the home. When it is left open in summer, most dust and insects come in this way. That is why choosing a filter for the balcony door matters especially.
Two methods
- If you have a hinged screen door: Remove its mesh and fit window filter by the roll in its place. Guide: fitting into a screen frame.
- If you do not have a screen door: Hook-and-loop kit is made to the size of your door and fitted to the frame. When you need to go through, the filter can be opened from one edge.
Made to measure: hook-and-loop or roll
