PM1 Air Filter - AFPRO Filters

Particulate Matter (PM) is categorized by size: PM10 (0.01mm), PM2.5 (0,0025mm) and PM1 (0.001mm), of which the latter is the most harmful form. After inhalation affect the different sizes of particulate matter each body in a different way. PM10: These are particles having an aerodynamic diameter of less than 10 micrometers. These particles are ...

Description. PM 10 is particulate matter 10 micrometers or less in diameter, PM 2.5 is particulate matter 2.5 micrometers or less in diameter. PM 2.5 is generally described as fine particles. By way of comparison, a human hair is about 100 micrometres, so roughly 40 fine particles could be placed on its width. PM 10 and PM 2.5 are not used for any application.
