Investigation of indoor air quality in classroom of school buildings is consider as prime concern because of its adverse effects on students health and performance. Students spend their most amount of time (6-7 h per day) in schools. Current study is investigation of indoor and outdoor air quality in school buildings during winter season. In this study indoor and outdoor air quality parameters in naturally ventilated school building located near to urban roadway in Manipal. Monitoring was done during winter season (32 days). The objectives of the present study are monitoring indoor and outdoor parameters like PM10, NO2, SO, and CO2 during winter season and suggesting mitigation measures for proper air quality. Relative humidity, temperature and classroom characteristics such as size of room, occupancy level also monitored during school hours. Results show that CO2 concentration in classroom over 1000 PPM during winter season due to small size of classrooms and more occupancy rate as per ASHRAE standards. Closing doors and windows can prevent only entry of outdoor PM concentration in inside room. For proper indoor air quality in school buildings mechanical ventilation system with proper air purification should be provide, also plantation of some indoor plants such as Anthurium, Dumb Cane, Golden Pothos, Kadaka Fern, Prager Plant, Spider Plant, and Syngonium etc. so it will help to reduce the indoor CO2
