Abstract

The aim of this study was to compare the concentrations of airborne pollutants (i.e., PMs, TVOC, and ozone)released from a laser printer with a new and/or a refilled toner cartridge. Also we compared theconcentrations before and after attaching a HEPA filter at the outlet of exhausted air for each printer.PMs, TVOC, and ozone were released from all three different branded printers with both toner cartridgesin accordance with their both a brand new and a used condition. For PMs, there were generallysignificant differences of concentrations between a brand new and used toner (p<0.05). Ozone leveldifferences were found between a new and a refilled toner, but were not significant (p>0.05). For TVOC,there were significant differences of concentrations among brands, and toluene (3.46mg/m3) only wasidentified. The overall 70% of reduction for PMs’concentrations occurred after attaching a HEPAfilter(p<0.05), and these results were pronounced for TSP.These results showed that similar levels of airborne pollutants were released from a laser printer with anew and a refilled toner cartridge. Also, these results indicate that the usage of a HEPA filter may be aneffective method for reducing the released pollutants from a laser printer.
