This work focuses on indoor air quality evaluation of commercial buildings in Kuantan. Some buildings have been selected to monitor indoor air quality. The research has been carried out only in Kuantan, which focused on hotels and government buildings. Some sample measurements were taken which include air temperature, relative humidity, and air movement, carbon monoxide (CO), carbon dioxide (CO2), ozone (O3), respirable particulate matter (PM 10), formaldehyde and total volatile organic compound (TVOC). In addition, questionnaires were conducted on a number of workers in each building to determine the level of health and illness caused by air in the building where they work. Hence, this study has analyzed the link between the questioner results and the results of indoor air measurements that were carried out. From surveys, it appears there are four buildings that have low air flow, four buildings have a lot of dust and five buildings have a high temperature. In contrast, four buildings have a good indoor air quality.

The coronavirus disease 2019 (COVID-19), which is mainly transmitted through droplets without overlooking other sources of transmission, rendered attention on the air quality in indoor areas and more specifically in healthcare settings. The improvement of indoor air quality (IAQ) is ensured by frequent changes of the air that must be carried out in healthcare areas and with assistance from special devices that undertake the filtration of the air and its purification through special filters and lamps. In this research, the performance of air purifiers is assessed in terms of the limitation of PM2.5, PM10, VOCs and CO2 in a postgraduate clinic of the Dentistry School of the National and Kapodistrian University of Athens in parallel with mechanical ventilation. Our findings indicate that the use of mechanical ventilation plays a key role on the results, retaining good IAQ levels within the clinic and that air purifiers show a positive impact on IAQ by mainly reducing the levels of PM2.5 and secondly of TVOC.
