The AirVisual air quality monitors are designed to detect these pollutants
The AirVisual Pro can monitor up to 5 environmental parameters; AQI, PM2.5, CO2, Temperature, and Humidity. While the AirVisual Outdoor can monitor up to 8 environmental parameters; AQI, PM1, PM2.5, PM10, Temperature, Humidity, Barometric Pressure and optional CO2.
AQI
Air quality index
AQI, or Air Quality Index, is a system for translating sometimes confusing or unintuitive pollutant concentration measurements, into one easy-to-understand scale to clearly represent the health risk posed by ambient air pollution.

PM1
Ultra-fine particles
Particulate matter (PM) less than 1 micron in size is called PM1 (sometimes PM1.0). PM1 is considered especially dangerous due to its extremely small size. The smaller the diameter of a particle, the more harm it can typically cause. Tiny airborne particles like PM1 are small enough to penetrate lung tissue and get into the bloodstream. PM1 can then circulate throughout the body and cause systemic health effects.

PM2.5
Fine particles
PM2.5 particles measure 2.5 microns or less in diameter. PM2.5 particles are so small they can only be seen with an electron microscope. Of all air pollution measures, PM2.5 pollution poses the greatest health threat (1). Due to its small size, PM2.5 can remain suspended in the air for long periods of time and can be absorbed deep into the bloodstream upon inhalation.

PM10
Coarse particules
PM10 is suspended coarse particulate matter, either solid or liquid, with a diameter of 10 micrometers (µm) or less. For comparison, a human hair is, on average, 50 to 70 µm in diameter.

Temp.
Temperature
Temperature is vital for air quality monitoring as it affects pollutant formation, dispersion, and sensor accuracy. High temperatures can increase pollution, while temperature inversions trap pollutants, worsening air quality. Monitoring it helps predict pollution risks and ensures accurate readings.

Humidity
Relative humidity
Humidity is important for air quality monitoring as it affects health, pollutant behavior, and sensor accuracy. High humidity can worsen respiratory issues, promote mold, and alter pollutant levels, while low humidity increases virus spread. Monitoring it ensures a healthier environment.

Barometer
Barometric pressure of high & low pressure systems
Barometric pressure is important for monitoring air quality because it affects the movement and dispersion of pollutants in the atmosphere. High pressure systems can cause stagnant air conditions, trapping pollutants close to the ground and leading to poor air quality. In contrast, low pressure systems can enhance air circulation, dispersing pollutants more effectively.

CO2*
Optional CO2 modules
At room temperature, carbon dioxide (CO2) is a colorless, odorless gas formed from carbon and oxygen atoms. The fourth most common gas found in the earth’s atmosphere next to nitrogen, oxygen, and argon, CO2can also be liquid or solid. In its solid form, CO2 is known as dry ice.

Made in Germany with Love
Every unit undergoes individual performance testing before leaving the factory, this includes verifying efficiency and sensor accuracy. Components such as the sensors use advanced data validation algorithms to ensure reliable measurements up to 10 years. Replaceable calibrated sensor modules eliminate the need for factory recalibration.
360° Air Quality Monitoring
IQAir Indoor Air Quality Monitors integrate with the AirVisual app. The app offers customizable alerts when air quality exceeds set thresholds and enables remote monitoring, making it easy to track and manage indoor air quality from anywhere. This integration provides seamless access to comprehensive air quality data, helping users make informed decisions to improve their environment.
