Question: 1 / 400

Which standard sets the baseline for air filter efficiency?

ASHRAE 62.1

ASHRAE 52.2

The standard that sets the baseline for air filter efficiency is ASHRAE 52.2. This standard specifically addresses the measurement of air filter performance, focusing on their ability to capture airborne particles and improve indoor air quality. ASHRAE 52.2 provides guidelines for testing filter efficiency at different particle sizes and establishes a rating system that can help designers and engineers select appropriate filters for their HVAC systems.

While ASHRAE 62.1 is concerned with ventilation and indoor air quality, it does not specifically focus on the efficiency of air filters. ASHRAE 90.1 primarily addresses energy efficiency in building design and operation, and ASHRAE 55 provides guidelines on thermal environmental conditions for human occupancy. Each of these standards plays a crucial role in building design, but ASHRAE 52.2 is the authoritative source for the air filter efficiency baseline.
