What type of screens should not be installed at the termination of a dryer vent?

The appropriate choice regarding dryer vent termination is that dryer vent screens should not be installed at the termination. This is because dryer vent screens can restrict air flow, potentially leading to inefficient dryer performance and increased risk of lint buildup, which can create a fire hazard.

Effective ventilation is critical for dryers to function properly, and the vent must be able to exhaust moist air and lint without obstruction. Lint can accumulate on screens, causing clogs that not only degrade the efficiency of the dryer but also pose serious safety risks.

In contrast, other types of screens or ventilation solutions, while they may have their own specific applications, are not typically placed at the end of a dryer vent due to the need for unobstructed airflow. Therefore, installing dryer vent screens is discouraged to ensure proper dryer operation and to enhance safety in mechanical systems.
