Particulate matter (also referred as particle pollution) is a mixture of liquid and solid particles suspended in the air. Both inorganic and organic particles including smoke, dust, soot, liquid droplets, pollen produce this mixture.
These particles differ greatly in composition, size, and origin. Some of the large particles are visible to our naked eye whereas, certain particles such as nitrates, copper, cadmium, zinc, nickel, hydrocarbons, sulfates, black carbon are tiny in size and are visible only through an electron microscope. Particulate matter can also contain some harmful microorganisms.
Most of these particles can be filtered with our particulate microfibre glass filter elements.
