PM2.5 are tiny airborne particles with a diameter of 2.5 micrometers or smaller. PM2.5 particles can stay suspended in the air for a long time and are small enough to be inhaled deep into your lungs. They can come from vehicle emissions, industrial processes, and even natural sources like dust and pollen.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">PM10 Meaning<\/h3>\n\n\n\n<p>PM10 (Particulate Matter 10): These are slightly larger particles with a diameter of 10 micrometers or smaller. While larger than PM2.5, they are still very small and can also be inhaled into your lungs. PM10 particles come from sources similar to PM2.5, including dust, vehicle emissions, and industrial activities.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1280\" height=\"720\" src=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2019\/04\/Particle-Sizes-Virus-Labelled.jpg\" alt=\"PM2.5 Particle Size Bacteria Virus\" class=\"wp-image-9754\" style=\"width:900px\" srcset=\"https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2019\/04\/Particle-Sizes-Virus-Labelled.jpg 1280w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2019\/04\/Particle-Sizes-Virus-Labelled-300x169.jpg 300w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2019\/04\/Particle-Sizes-Virus-Labelled-768x432.jpg 768w, https:\/\/smartairfilters.com\/wordpress\/wp-content\/uploads\/2019\/04\/Particle-Sizes-Virus-Labelled-1024x576.jpg 1024w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><\/figure><\/div>\n\n\n<h3 class=\"wp-block-heading ui_qtext_para u-ltr u-text-align--start\"><b>PM2.5 vs. PM10<\/b><\/h3>\n\n\n\n<p class=\"ui_qtext_para u-ltr u-text-align--start\">The difference between PM10 and PM2.5 is size.
