Cyclone Ventilator Modification: An Environmentally Friendly Solution for the Homes of Patients With Tuberculosis and Acute Respiratory Infections

Poor indoor air quality is one of the factors that can cause health problems. Tuberculosis (TB) and acute respiratory infections (ARIs) are among the diseases often associated with indoor air quality. In 2022, the highest number of TB cases was recorded in Surabaya, with 4739 cases. The research location, at the Wonokusumo Public Health Center, still reported a high number of TB cases, with 126 cases in 2022 and 84 cases in 2023. The use of Cyclone Ventilator Modification (CVM) has shown to improve the indoor air quality of occupants. This study aims to analyze the capability and the time required for the CVM to enhance the indoor air quality in homes of TB and ARI patients, using indicators such as temperature, humidity, airborne microbiology, air flow rate, PM 2.5 dust particles, and lighting. This experimental study uses a One Group Pre‐Test Post‐Test Design to test changes following the experiment. The device operates on the principle of improving air quality, including temperature, humidity, air flow rate, lighting, and the ability to reduce airborne microbiology and PM 2.5 dust particles indoors. The effectiveness of the CVM in improving indoor air quality for TB and ARI patients is analyzed using a paired T ‐test analysis, revealing significant differences in indoor air quality indicators before and after the device’s operation. The results obtained show that the two‐tailed significance value is less than 0, indicating a significant difference between the initial and final variables. After CVM operation in five homes with eight replications, the CVM’s effectiveness was optimal in relation to room area/volume. This study was conducted as a simple step to minimize pollutants and improve indoor air quality. These findings can be applied and utilized to create healthier buildings or homes.
