Abstract
The presence of air pollutants in a room can cause health problems both in the long run and short term. One of the indicators of indoor air pollution is dust/particulates. Air pollution comes from incomplete combustion activities from households, cigarette smoke, household industries, building materials, etc. The purposes of this study are to analyze the life time of activated carbon for dust filtration after passing through the cyclone ventilator modification; to analyze its effectiveness in lowering dust levels; to analyze its efficiency rate in lowering dust levels, and; to evaluate the ability of the cyclone ventilator modification to reduce the dust levels. The research design was a pre-experimented research in the form of One Group Pretest-Posttest design. The independent variable was the cyclone ventilator while the dependent variable was dust. The data collections of the dust were conducted 100 times, before and after the air passed through the cyclone ventilator. The data analysis employed was the paired t-test. The results showed a decrease in temperature of 1.18 after the installation of the indoor air purifier at an average air speed of 8.51 m/s. Before passing through the indoor air purifier, the average dust level reached 0.29 mg/m o C . Meanwhile, the average dust level after passing through the ventilator decreased to 0.0039 mg/m 2. 2 The average percentage of dust level reduction was 98.68%. The paired t-test analysis indicated p=0.000, meaning that there was a significant decrease of dust level after the air passed through the air purifier. The life time of the activated carbon for dust filtration had not reached its saturation point after 400 hours. This ventilator was highly effective as it could reduce dust level by more than 80% for 400 hours. Meanwhile, the efficiency was evident from the effectiveness of the ventilator in lowering the dust level at a relatively low cost since the operation did not require electricity. The conclusion of the study was that this cyclone ventilator modification had an excellent capability as indicated by its life time rate as well as its effectiveness and efficiency in lowering indoor dust levels. It is recommended that the cyclone ventilator modification be applied in an effort to promote healthy indoor air quality for both households and home industries.
