What Air Pro senses in the air
There are two sensors within Air Pro: a particulate sensor and a chemical sensor.
The laser-based sensor in Air Pro is designed to detect particles, giving you a window into the air in the room it’s operating in, to help maintain clean air. Using a laser and light-sensitive detector, the sensor counts particles that reflect light and gauges how much of it is in the air.
Airborne particles, or particulate matter (PM), can contain a range of microbes, allergens, and bacteria. Air Pro’s sensor can detect three size ranges of particles, from about 1/5th down to 1/50th the width of a human hair. But there’s more to air pollution than just particles. While the particle sensor doesn’t measure other types of pollution like ozone, VOCs, and some allergens, you can rest assured that the unique PECO technology at the core of your device is working to destroy them.
A window into your air
Your Air Pro’s sensor measures different particle sizes in a cross section of the air of the room it’s operating in, giving you insight into your air. It can sense three sizes of particles, known as PM (particulate matter):
PM10: Coarse particles 10 microns or smaller in width (about 1/5th of a human hair). Includes pollen, bits of mold, dander, and other matter common to indoor air.
PM2.5: Fine particles 2.5 microns or smaller in width (about 1/20th of a human hair). Includes dust, bacteria, and other matter common to indoor air.
PM1.0: Microfine particles 1 micron or smaller in width (about 1/50th of a human hair). Includes smoke particles, some bacteria, and other matter common to indoor air.
While Air Pro can read the size of particles in a cross section of the air, it cannot read what they are. The examples in parentheses above are size references for different types of particles. The sensor in Air Pro can measure particles down to 0.3 microns.
