Four environmental factors — particulates, temperature, humidity and gaseous pollution —have been shown to damage historical artifacts and materials. Of these, gaseous pollution is the most destructive. From the Sistine Chapel to the Smithsonian, Purafil protects archives and works-of-art around the world from gaseous pollutants. Based on decades of research, we have developed comprehensive design standards for numerous preservation applications. Our solutions for air quality assessment, filtration of harmful pollutants, and air quality monitoring set the standards for the safeguarding of history.

• Air Quality Assessment
Purafil provides Environmental Reactivity Coupons (ERC) to determine the severity level of airborne pollutants in multiple areas of your facility before control measures are implemented. Upon analysis of your ERCs, Purafil’s laboratory issues a comprehensive report detailing each area’s air quality classification, the concentrations of pollutants present, and humidity effects.

• Air Filtration
Purafil specializes in the engineering and manufacture of chemical filtration solutions to provide safe environments for the storage and display of collections. We offer custom filtration media and systems to meet the requirements of any area or application. Our techniques have been tested under a myriad of facility conditions, are technically proven, and cost effective.

• Air Quality Monitoring
Purafil’s patented OnGuard Environmental Reactivity Monitor (ERM) provides continuous, real-time air quality measurements. Use the OnGuard ERM to establish air quality trends and take preventive action before serious damage occurs.
