What is the name of the current European Air Filter Standard?

The correct answer is based on the significance of the European Air Filter Standard EN 779:2002. This standard was established to categorize and evaluate air filters for general ventilation by their efficiency in removing airborne particles from the air. EN 779:2002 provides a framework for testing, reporting, and understanding the performance of air filters, ensuring that they meet specific filtration requirements and can reliably improve indoor air quality.

This standard plays a crucial role in guiding manufacturers and consumers in the selection of appropriate air filtration solutions. The designation and the year of the standard are important because they reflect the periodic updates that aim to align with advancements in air quality management practices.

In contrast, the other options do not pertain to the current standard used specifically for evaluating air filters for ventilation. While they may refer to various aspects of filtration or other unrelated standards, EN 779:2002 is the recognized norm for air filter performance in Europe.
