Abstract

The application of photocatalytic oxidation (PCO) in air purifiers (AP) to remove viruses, bacteria and toxic gases in the air is intensively being studied, especially after the Covid-19 pandemic broke out. The testing method of PCO materials for AP purpose has been standardized though ISO 22197-4 (2013). However, the standard required a set of complex, high precision, and costly equipment. Present study demonstrates a simpler and low-cost test setup without compromising any accuracy in the overall result. The proposed test consists of test chamber and mixing chamber, and sets of equipment installed in it. PCO reactor was fabricated by 3D printer and and \(TiO_{2}\) was coated on the surface. Formaldehyde is used as a sample pollutant to be observed which is injected to the test chamber. The amount of formaldehyde concentration was monitored online by indoor air quality measurement equipment.
