Industry Guidelines
The National Air Filtration Association creates best practice guidelines unique to each specific industry. Some of our staff are continuously contributing to these guidelines based on our over 50 years of experience as a leader in the air filtration industry.
What Are NAFA Best Practice Guidelines?
The National Air Filtration Association (NAFA) develops best practice guidelines for filtration across a variety of industries and facility types. These resources help facility owners, managers and HVAC professionals understand filtration considerations and recommended practices for their environments.
NAFA Best Practices Industry Guideline Library
Filtration for Airborne Infections Containment Rooms in Health Care Facilities
This best practice guideline establishes criteria for using air filtration in the removal of airborne infectious pathogens from hospital containment rooms for the purpose of protecting staff, patients and visitors from nosocomial infections.
Filtration for Commercial Office Spaces
This best practice establishes air filtration guidelines for the removal of particulate, bioaerosols, and gaseous contaminants for the protection of the air handling equipment and components, as well as providing comfort and a healthy environment for all who work and visit commercial office spaces.
Filtration for Air Filtration in Computer Data Centers
Data Centers require highly controlled air quality to protect critical Information Technology (IT) infrastructure from airborne contaminants such as particulate, volatile organic compounds (VOC’s), and corrosive gases.
