Data Analysis of Indoor Air Quality with and without HEPA Filter in Air Purifier (Study Case: East Jakarta Residential Area)

Abstract

Humans in good health breathe air containing 21% oxygen 12 times per minute at rest. The number of breaths increases as people engage in activities. Humans need clean air to live. Therefore, measuring indoor and outdoor air quality is essential for a better lifestyle. Some circumstances and causes may impact the outcome in fine particulate matter PM2.5. Air purifiers and filtration systems were needed to be tested in East Jakarta, Indonesia, to improve indoor air quality. Different filter types are used to categorize air purifiers. HEPA filters have been created and enhanced as part of continual efforts to preserve clean, breathable air. Air purifiers decrease particulate matter with HEPA filters. This study aimed to determine how an air purifier's HEPA filter impacts air quality in a residential area of East Jakarta, Indonesia. This research contributes to a solution whether to use or not to use air purifiers indoors to have better air quality. The air quality in the East Jakarta residential area during the research period was shown to be directly improved from 8.88 to 10.49 mg/m3 with standard deviations of 9.01 to 10.18 mg/m3 for particulate matters when an indoor air purifier with a HEPA filter turned on in seven days.
