What is the minimum mesh size required for screens on windows and doors?

1. 12 inch mesh

2. 14 inch mesh

3. 16 inch mesh

4. 18 inch mesh

The correct answer is: 16 inch mesh

The correct answer reflects the minimum mesh size required for screens on windows and doors, which is typically designated to ensure effective pest control while allowing adequate air flow. A mesh size of 16 inches is commonly recognized as an industry standard, providing a balance between filtering out small insects and maintaining visibility and airflow. This size is effective at keeping out a majority of common pests like mosquitoes and flies, which are significant concerns in residential settings. Choosing a smaller mesh size would potentially allow pests to enter through the screen, compromising the intended purpose of the screen. Meanwhile, larger mesh sizes could lead to enhanced airflow but fail to adequately block unwanted insects. Therefore, 16 inch mesh is seen as an appropriate choice that effectively meets both safety and comfort standards in residential environments.
