What is the primary purpose of a screen door?

The primary purpose of a screen door is to keep out insects while allowing air flow. This feature is particularly valuable in warmer months when homeowners wish to enjoy fresh air and ventilation without inviting bugs into their living spaces. Screen doors typically have a mesh design that effectively blocks insects yet permits air to pass through, enhancing comfort within the home.

While other options discuss important door purposes, they do not specifically align with the fundamental function of a screen door. For instance, security from intruders is more typically a role played by solid entry doors, while protection against severe weather is better suited to storm doors. Enhancing privacy can be achieved by using curtains or frosted glass rather than a screen door, which is primarily designed for insect protection. This makes the option about keeping out insects and allowing airflow the most accurate choice concerning the primary purpose of a screen door.
