NAFA Air Filtration Best Practice Guidelines
Many international HVAC/R organizations promulgate standards for the air filtration industry, and many of these standards become part of a national building code. For the most part, these codes dictate “minimum standards” that must be met to be in compliance with the code. NAFA publishes a series of air filtration best practice guidelines based on these codes, but that go further to recommend and incorporate the “highest level of air filtration standards” for specific applications.

These best practice guidelines establish 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.
These best practice guidelines establish air filtration guidelines for the removal of particulate contamination for the protection of the air handling equipment and components, as well as providing comfort and a healthy environment for all who work, visit, live and play in these facilities. The recommendations in this guideline are considered by NAFA to be “best practice” in contrast to “minimum standards” as put forth by other organizations. It will serve to provide owners and facility managers with the necessary information to make educated decisions when providing filtration products for their building, and an essential component of their Indoor Air Quality (IAQ) and life safety program.
