Best Practice Guidelines

What’s the difference between ASHRAE Standard 52.2 and NAFA’s Best Practices and Guidelines?

The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) has minimum standards for air
filtration. Organizations like the National Air Filtration Association (NAFA) go beyond these minimum standards. NAFA publishes
best practices and guidelines for several facility applications based on the experience and expertise of their membership, as well as
current mandates and research provided by governmental and scientific communities. HVAC and air filtration professionals should
use NAFA’s Best Practices and Guidelines as a tool to educate their clients on how to protect their facilities’ occupants.
