Comparison of test methods for toluene removal performance of air cleaners

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