Particulate Matter Size Comparison

Comparison of PM pollutants with human hair

Particulate Matter (PM) is a combination of solid particles and liquid droplets suspended in the air. Due to their minute size, these particles can enter the lungs and impact long-term health.

  • PM1

    1µm or smaller

  • PM2.5 particle size illustration

Understanding Air Pollutants: PM

Particulate Matter (PM) is categorised by its diameter, with PM2.5 (fine particles) and PM10 (coarse particles) being the most significant for air quality monitoring.

  • PM1 pollutant iconPM1
  • PM10 pollutant iconPM10
  • PM2.5 pollutant iconPM2.5
  • PM2.5 pollutant iconPM2.5
  • PM1 pollutant iconPM1
  • PM10 pollutant iconPM10

Learn about each PM size

  • PM1

    These are particles with a diameter of 1 micrometre or smaller. They are capable of entering the bloodstream and causing systemic health complications.

  • PM2.5

    Fine particles smaller than 2.5 micrometres. They are small enough to reach deep into the lungs, potentially leading to chronic respiratory issues.

  • PM10

    Particles with a diameter of 10 micrometres or smaller, such as dust and pollen. While larger, they can still cause irritation and respiratory allergies.

  • Particle Count

    This metric represents the total number of particles present in the air, providing a broader view of overall air quality regardless of specific particle size.

Pollution Sources:

  • Vehicle exhaust as a source of PM pollutionVehicle Emissions
  • Factory emissions as a source of PM pollutionIndustrial Discharge
  • Construction sites as a source of PM pollutionConstruction Activity
  • Wildfires and smoke as sources of PM pollutionWildfires
  • Unpaved roads as sources of PM pollutionRoad Dust

Accuracy Validation: Prana Air vs. BAM

Comparison of Prana Air sensor data with BAM reference system

In a comprehensive evaluation, Prana Air's PM sensor was benchmarked against the high-end Beta Attenuation Monitoring (BAM) system.

The results showed a high degree of correlation, confirming that our sensor delivers near reference-grade accuracy.

Our Sensors Case Studies

Case Study By IIIT Hyderabad

Comparative Evaluation of New Low-Cost Particulate Matter Sensors

Study Brief : So, the paper involves our Prana Air device alongside other low-cost sensors for PM2.5 and PM10 measurements. For the results, they compared them to the standard Aeroqual Series-500. Since, their challenge with traditional devices was the high cost, heaviness, and frequent service needs, which limited usin in cities.

comparison of PM sensor data between Aeroqual and Prana Air before and after calibration

Note : Monitors update in every 30 seconds, moreover our PM sensors have a resolution of ±1.0 micrograms per cubic meter, and our NO2 sensors boast a resolution of ±1.0 ppb.

Case Study By NEERI (CSIR)

Performance‐based protocol for selection of Affordable and easy to carry sensor for air quality measurement

Study Brief : In their research, they used our device in their Environmental Protection Sensors (EPS) assessment. So in this, they compared factory calibration data with reference monitors. Because, their challenge was reasonable cost with accuracy, sensitivity, and data management. In the result, Prana Air proved to be a reliable and affordable choice.

Frequently Asked Questions

The Prana Air PM Sensor is a digital laser-based device designed for precise monitoring of PM1, PM2.5, and PM10 levels in outdoor environments. It employs advanced 90° light scattering for real-time accuracy.

The sensor covers a measurement range from 0 to 31,000 µg/m³, making it suitable for both ambient monitoring and highly polluted industrial or construction settings.

It can detect particles as small as 0.3 micrometres (µm). These microscopic pollutants are small enough to reach the lungs and bloodstream, making precise detection essential.

The sensor has been cross-validated against global reference-grade monitors like Beta Attenuation Monitoring (BAM) systems and TSI DustTrak. Independent studies from international research bodies have confirmed its high correlation with industry standards and reference-grade accuracy.

Our technology is trusted by a wide variety of global organisations across the research, healthcare, and industrial sectors, including the Boston Consulting Group (BCG) and numerous international universities and environmental agencies.

The sensor has been successfully deployed at over 2,000 construction and industrial sites globally, demonstrating its reliability and durability in demanding field conditions.

Key features include a dust-proof duct to prevent clogging, a moisture-resistant circuit board, and a closed-loop fan system for stable airflow. It is designed to operate from -20°C to +70°C and in up to 99% humidity.

The sensor connects to a monitoring station that transmits data to the cloud via Wi-Fi, GSM, or RS-485. This data can then be accessed in real-time via mobile or desktop dashboards.
