Introduction: The Indian Statistical Institute (ISI), a premier research institution. They wanted to monitor air quality in governmental schools across Delhi for a research study. ISI required robust, tamper-proof air quality monitors. Also, they wanted air purifiers that could securely store data without any manual intervention and withstand outside conditions. Here know how Prana Air helped the Indian Statistical Institute (ISI concerns by offering advanced air quality monitors and durable air purifiers for the project’s needs.
The Challenge
ISI’s research required the deployment of air quality monitors and purifiers in governmental schools across Delhi. The key challenges included:
- Tamper-Proof Solution: Both monitors and purifiers needed to be robust and secure to protect from tampering by students, staff, or other factors.
- Zero Manual Intervention for Data Collection: The monitors should collect and store air quality data without any human intervention. As to ensure accurate data integrity for research reliability.
- Restricted Access to Readings: The readings are visible for monitoring purposes, but access or manipulation of the data should be prevented.
- Durable Air Purifiers: The air purifiers must have a strong metal body to ensure longevity and resistance to tampering in a school environment.
- Comprehensive Monitoring: The monitors needed to track multiple parameters, including PM2.5, PM10, humidity and temperature.
Prana Air’s Solution
Prana Air helped by providing the best customised solution to meet the Indian Statistical Institute’s (ISI) requirements. As By providing a combination of Ambient PM air quality monitors and robust air purifiers for Delhi’s governmental schools.
Deployment of Ambient PM Air Quality Monitors
Prana Air helped the Indian Statistical Institute (ISI) by providing a total of 225 Ambient PM air quality monitors across Schools in Delhi.

Key Features of the Ambient PM Air Quality Monitor:
- Robust Design with IP86 Housing: The monitors are full-fledged with IP86-rated housing, making them dust-tight and resistant to water. This ensures the durability and protection against tampering in the school environment.
- Tamper-Proof Data Access: The readings are visible on the monitor’s display for real-time observation. However, the data cannot be altered or accessed directly. This ensures the integrity of the research data.
- Comprehensive Monitoring Capabilities: The monitors measure PM2.5, PM10, and temperature, providing ISI with a complete dataset for their research.
- Autonomous Data Storage: Each monitor featured Micro SD card storage, enabling continuous data logging without human intervention. Thus, this allows ISI to retrieve air quality data at their convenience for analysis.
- Optional Connectivity Features: The monitors also offer GSM and cloud storage options for real-time data access. But ISI opted for SD card storage to maintain full control over data retrieval and minimise external dependencies.
Supply of Robust Air Purifiers
Besides the monitoring solution, Prana Air also helped the Indian Statistical Institute (ISI) by providing 35 air purifiers. The Blue Air Classic 200 Series Air Purifier, the following features:

- Sturdy Steel Body: The air purifiers have a solid steel body, ensuring they are tamper-proof and durable in the school setting.
- High Clean Air Delivery Rate (CADR): The purifiers have a CADR of 340 m³ per hour (350 cfm) for smoke, pollen, and dust. It making them highly effective at removing pollutants.
- Advanced SmokeStop™ Filter: This filter technology efficiently removes bacteria, allergens, and odours, ensuring cleaner air for students and staff.
- Coverage Area: Designed for rooms up to 26 m², the purifiers are ideal for classrooms, with an air change rate of 4.8 times per hour.
- Wi-Fi Connectivity for Remote Control: The purifiers support Wi-Fi connectivity, allowing remote monitoring and control.
- Integrated Air Sensors and Filter Replacement Indicator: The purifiers came with built-in air quality sensors and a filter replacement indicator. As tp ensurg optimal performance without manual oversight.
- Energy Efficiency and Quiet Operation: With an energy consumption of 20–80 watts and a sound level of 32–56 dB(A). The purifiers have energy-efficient and quiet, minimizing disruptions in the classroom.
- Additional Features: The purifiers offer 1–2–3 auto speed options, an on/off timer, and dimensions of 533 x 432 x 209 mm, with a weight of 11 kg, making them compact yet powerful for school use.
Conclusion
Prana Air’s collaboration with the Indian Statistical Institute demonstrates the effectiveness of advanced air quality solutions in a challenging environment. By providing robust, tamper-proof Ambient PM air quality monitors and durable Blue Air Classic 200 Series air purifiers. Prana Air helped the Indian Statistical Institute to conduct its research. Prana Air’s commitment to innovation and reliability made them a trusted partner in this impactful initiative.
