Efficiency of Conventional Air Purifier and Coconut Shell Activated Carbon Improving Indoor Air Quality

Abstract

There several types and technologies of air purifier such as by
electrification, biomaterial, ceramic and synthetic material. That
technology were very challenging to investigate their effectiveness on
improving air quality. Therefore, this research will be investigating
the conventional air purifier and coconut shell activated carbon in
improving IAQ. The method will be conducted by indirect
carbonization process and followed by crushing process to produce
the particle size of 18 mesh. The crushed coconut shell charcoal
activated by chemical activation using NaOH with ratio of 1:1 for 4
hours. The research will be conducted in office room by comparing
the conventional air purifier of particle counter DAZ-400 and
Coconut Shell Activated Carbon (CSAC). There are 3 various
samples in this research such as by air purifier (type 1), by CSAC
(type 2) and by combination of air purifier and CSAC (type 3). The
result shows that combination methods has lowest PM2.5, PM10 and
Air Quality Index of 7, 16.56 μg/m3 and 1 AQI respectively. The
combination technique (type 3) also shows the highest efficiency of
84.46% as compare to air purifier (type 1) and CSAC (type 2)
samples. Therefore, the combination filtration process by using air
purifier and CSAC was very recommended to applied in office room
to improve the IAQ.
