This best-recommended practice establishes air filtration guidelines for the removal of particulate and gaseous contaminants for the protection and long-term preservation of historical documents and artifacts. The recommendations in this guideline are considered by NAFA to be “best practice” in contrast to “minimum standards” put forth by other organizations.
