PM2.5 Activated Carbon Filter - 5 Layers Replaceable Protective Parts Filters Air Filtration for Adult, Cut Smaller for Children - 50pcs Brand: JingXiGuoJi 4.4 out of 5 stars 237 ratings A PM2.5 filter is a disposable insert that improves a mask's filtration effectiveness, especially against the smallest aerosolized particles. A certified pm2.5 filter used with a fitted cloth mask can block the vast majority of airborne particulates, i ncluding fine aerosols. PM 2.5 stands for the term ‘fine particulate matter’ and represents air pollutant particles that are up to 2.5 µm in size and composition (Aerosol Aerodynamic Diameter is less than 2.5 µm).

Man definierar alltså partiklar i luften utifrån partiklarnas storlek. PM10 är partiklar som är mindre än 10 mikrometer (µm) i aerodynamisk diameter, PM2.5 är

The 2.5 in PM 2.5 refers to the sizeof the pollutant, in micrometers. The tinniest thing which the human eye can see is at least 0.1 millimeters, about the width of a strand of fine air (70 micrometers). For you to see something as small as a micrometer, you need to use microscopes. Fine particulate matter (PM 2.5) is an air pollutant that is a concern for people's health when levels in air are high. PM 2.5 are tiny particles in the air that reduce visibility and cause the air to appear hazy when levels are elevated.
