Museums and Archives

Maintaining high indoor air quality is a top priority for Museums & Archives due to the fact that indoor air can be up to five times more polluted than outdoor air. To successfully preserve historical documents, artifacts, metals, photographs, and architecture, it is crucial to control and mitigate exposure to gaseous contaminants and particulate matter.

If left unchecked, these pollutants can cause sensitive items to discolor, deteriorate, and degrade at an accelerated rate, ultimately leading to the loss of valuable assets, funding, and reputation. To prevent this, it is important to identify and address common gases that negatively impact sensitive items, including hydrogen sulfide, nitrogen dioxide, sulfur dioxide, formaldehyde, ozone, and halogens. By taking proactive measures to regulate and improve indoor air quality, we can help safeguard these important cultural artifacts for generations to come.


Libraries Archives & Museums - Best Practices and Guidelines for Air Filtration - English

Updated for 2023 – These best practice guidelines establish criteria for the removal of particulate and gaseous contaminants for the protection and long-term preservation of historical documents and artifacts.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. They serve to provide the conscientious Facility Manager with the necessary guidelines to make measurable differences of air quality in his/her building.
