Understanding Particulate Matter (PM1, PM2.5, PM10) Metrics on Airthings View Plus
The Airthings View Plus is equipped with advanced sensors to monitor air quality, including particulate matter (PM) levels. This article explains the device's capabilities and documentation regarding PM1, PM2.5, and PM10 metrics.
Overview of Particulate Matter Metrics
Particulate matter (PM) refers to tiny particles or droplets in the air that can be harmful when inhaled. These particles are categorized by size:
PM1: Particles with a diameter of 1 micrometer or smaller.
PM2.5: Particles with a diameter of 2.5 micrometers or smaller.
PM10: Particles with a diameter of 10 micrometers or smaller.
Officially Supported Metrics
The Airthings View Plus officially supports and documents PM2.5 as its primary particulate matter metric. This metric is the focus of the device's air quality monitoring capabilities.
Detection Capabilities for PM1 and PM10
While PM2.5 is the main officially supported and documented metric, the View Plus also can detect PM1. The device can detect particles in the PM1 size range, and PM1 values may be displayed in the Airthings mobile app.
PM10: we do not not support PM10 measurement.
Technical Details: Laser Scattering Optical Particle Counter
The View Plus uses a laser scattering optical particle counter to detect particulate matter. This sensor operates within a detection range of approximately 300 nanometers (0.3 micrometers) to 10 micrometers. While the device primarily measures and reports PM2.5, its detection range allows it to identify larger particles that fall within the PM10 category.
Key Takeaways
PM2.5 is the officially supported and documented metric for the Airthings View Plus.
PM1 sensor data is also shown
We do not measure PM10
The device's laser scattering sensor provides a broad detection range, enhancing its air quality monitoring capabilities.
