Indoor air quality has been a major public concern recently. Several health effects are related to this problem.
Findings from several studies have shown MVAC system as the main contributor for IAQ problem. Good practice of
maintenance and servicing is important to maintain MVAC system, especially the filter. Good air filtration for MVAC
system is needed to make sure adequate air is received by the occupants. This paper illustrated a recent study of air
filtration for MVAC system especially for several industries that used MVAC system in their premises. This paper also
proposed an air filtration study for a better air quality. Several Acts and Regulations related to Safety and Health were
identified to create the framework for the proposed study. Air filtration technique was used in this preliminary study
to set up guidelines to create safe and clean indoor spaces for workers and occupants.
A poor Indoor Air Quality (IAQ) is a crucial problem which produces by the improper maintenance of Mechanical Ventilation and Air Conditioning (MVAC) ducting. A budget constraint intimidates for the practise of monitoring of the MVAC ducting. Thus IAQ measurements were conducted at the room where the air supplied by centralized air conditioning. It has been performed at four different offices that supply by two different Air Handling Unit (AHU). Walkthrough survey was conducted and the area samplings were selected for data collection. This paper examines the result of comparison of air ducting and air quality at academic office building, Universiti Tun Hussein Onn Malaysia (UTHM). The parameters involved were Temperature (°C), Relative Humidity (RH), Carbon Dioxide (CO2) and Carbon Monoxide (CO). Pictures were also captured to demonstrate the real conditions inside the ducting by using Mechanical Robot. Thus, duct cleaning was recommended to be an exceptional platform for the IAQ improvement.
