Snake plants, one of the air purifiers can significantly improve indoor air quality in the kitchen, non-ventilation, and ventilation area and improve indoor air pollutants such as HCHO and TVOC with a consistent temperature, while indoor air pollutants such as PM 2.5 and PM 10 have less effectiveness in reduction by snake plants. Ventilation also contributes to the reduction of indoor air pollutants. From the study, students’ mood and productivity are at a high level, whereas high in stress level during placing snake plants. There is a strong positive relationship between humidity and mold growth, which is one of the major issues in a hostel, and a study found that snake plants may influence in reducing mold growth by regulating humidity levels. This study can play an important role in enhancing indoor air pollutants in the hostel, making it environmentally friendly, cost-effective, and easily accessible for students living in the hostel.
