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.
