Abstract

Introduction: Poor indoor air quality gives potential negative effects on human health especially children due to their susceptibility to the air pollutants which their physiological conditions are still in the development process. Hence, air purifiers have been demonstrated to reduce the level of IAQ parameters, thus giving beneficial effects on human health. Objective: This study aims to determine the concentration of IAQ parameters between daycare centres with and without the use of an air purifier. Methodology: Purposive sampling was used in selecting the daycare centre with and without air purifier at Bangi areas. The walkthrough inspection was conducted and 5 parameters of IAQ which include PM2.5, CO2, bioaerosol (bacterial and fungal), relative humidity and temperature were assessed in this study. A standardized and modified questionnaire adopted from The International Study of Asthma and Allergies in Childhood (ISAAC) was distributed to 46 parents for sociodemographic and respiratory symptoms. Result: The result showed that there is a significant difference between PM2.5, CO2, bacteria and fungi concentration in studied areas. Daycare centres with air purifiers (DC3) found the lowest concentration of PM2.5 (18.2 μg/m3) and bacterial count (148 CFU/m3) except for fungal counts and CO2 level. The finding showed that PM2.5 in daycare centres without air purifier (DC1) had the highest (39.1μg/m3). All IAQ parameters not exceed the NAAQs and DOSH standard except temperature in all DCs and PM2.5 in DC1. All respiratory symptoms show no significant difference between both studied and comparative groups except for asthma. The higher number of children in DCs without air purifiers experiences a productive cough and allergic reaction compared to DC with an air purifier. Conclusion: The finding suggests that daycare centers with air purifiers are able to reduce those air pollutants and decrease the risk of respiratory symptoms among respondents. Keywords: IAQ parameters, daycare centers, air purifier, respiratory symptom
