Comparison of test methods for toluene removal performance of air cleaners
Abstract
The removal efficiency of VOC was tested for five air cleaners selected in terms of type and cleaningperformances. Toluene, representative VOCs, was selected and used as the test gas. In order to indicatetoluene removal capacity, toluene removal efficiency in a chamber and a duct was investigated with differentmeasurement devices such as gas detecting tubes and GC/MSD. Changes in toluene concentration in thechamber were measured with GC/MSD. The test results showed that the performances of the test modelsin the test chamber were superior to those in the duct, however, they did not differentiate the performancesof test models. According to our test study, toluene removal capacity calculated from the changes in tolueneconcentration with time was a good indicator for VOCs removal performance.
