Abstract
Abstract Population and industrialization growth is the major reason for the indoor air quality depletion. So, air quality control in sensitive area is needed to avoid air pollution-based hazards. Small economical air pollutant controlling equipment may be helpful in indoor air quality control. Present work covers the performance study of lab scale air purifier tower, 37 × 37 × 140 cm3 (LSAPT) for the removal of PM2.5, PM10 and TVOC from the polluted air in a control volume (75 m3). LSAPT follow 3 step pollutants removal procedure in which coarse particles are separated by prefilter and the fine particles are separated with the help of negative ioniser and activated carbon beds. More than 99 % of percentage of PM2.5, PM10 and TVOC removal are achieved within 100 s for initial pollutants loading of PM2.5: 1000 μg/m3 & PM10: 1000 μg/m3 and TVOC: 7.2 mg/m3 respectively. The assessment study suggests the proposed lab scale air purifier tower can be used continuously up to 10–15 days without much variation in pollutants removal efficacy. Approximately 7700 ₹ (92.40 US$) is used as installation cost and 30 ₹/hr (0.36 US$/hr) is used as consumable energy cost.
