FACILITY TYPE: Museum

LOCATION: Washington, D.C.

EQUIPMENT/MEDIA USED: Chemisorbant Media

PROBLEM: A confidential museum tested its environment for harmful gases to see what could be potentially harming its artifacts. The results showed nitrogen dioxide (NO2) and sulfur dioxide (SO2) to be the main culprits, testing at levels as high as 22.21 ppb and 1.68 ppb respectively. These levels of gases could cause irreversible damage to valuables in the museum over time. Because the museum was familiar with gas-phase filtration technology, it chose three companies to participate in a blind 3rd party test to see which products could remove the gases, with the winner gaining the business.

SOLUTION: PureAir’s media outperformed the competition, lowering the level of NO2 in its environment by 50% from 2.2 to 1.1 ppb. The next best competitor was only able to lower the gases by 33% of its initial reading. Impressed by the performance of PureAir’s chemisorbant media, it was chosen for the job, and the museum continues to rely on this solution today.
