Abstract
A method for evaluating an air purification system. The method includes generating, with an air flow generator, a flow of air through a test filter so that an upstream air flow exists an upstream side of the test filter and a downstream air flow exists on a downstream side of the test filter. A multiple contaminant mixture is injected, with a fluid injector, into the upstream air flow. Downstream concentrations for each contaminant of the multiple contaminant mixture in the downstream air flow are measured with a contaminant measurement device. Test filter breakthrough curves for each contaminant of the multiple contaminant mixture in the downstream air flow are generated based on the downstream concentrations for each contaminant of the multiple contaminant mixture.
