Auto Protect & particle levels
Particle sensor
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.
