Air Quality 

Good air quality is important to archival records and to the people who care for them. If you have air and ventilation systems, they should always be on to assure proper air quality; and you should use filters or vents to eliminate gases, dirt, and solid particles in the air. 

Whether you have air and ventilation systems or not, make sure that you keep chemicals out of archival work and storage areas: These chemicals include:   

• Cleaners with ammonia/chlorine
   
• Polyurethane/oil based paints
