Fine particles (PM2.5) are 2.5 micrometers in diameter or smaller, and can only be seen with an electron microscope.
Fine particles are produced from all types of combustion, including motor vehicles, power plants, residential wood burning, forest fires, agricultural burning, and some industrial processes.
Pollen and dust are totally controlled as they are 10 times bigger diameter size than PM 2,5 membrane.
In ¨Aire filters¨ there are different layers of dust collectors that helps to effectively remove large to moderate-size particles (fine dust) from the air, that penetrates into your respiratory system
PM2.5 refers to atmospheric particulate matter (PM) that have a diameter less than 2.5 micrometers, which is about 3% the diameter of a human hair.
Commonly written as PM2.5, particles in this category are so small that they can only be detected with an electron microscope.
Fine particles can come from various sources. They include power plants, motor vehicles, air planes, residential wood burning, forest fires, agricultural burning, volcanic eruptions and dust storms.
