What is PM, and how does it get into the air?Size comparisons for PM particlesSize comparisons for PM particles

PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.

Particle pollution includes:

  • PM10 : inhalable particles, with diameters that are generally 10 micrometers and smaller; and
  • PM2.5 : fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.
    • How small is 2.5 micrometers? Think about a single hair from your head. The average human hair is about 70 micrometers in diameter – making it 30 times larger than the largest fine particle.

Sources of PM

These particles come in many sizes and shapes and can be made up of hundreds of different chemicals.  Some are emitted directly from a source, such as contrstuion sites, unpaved roads, fields, smokestacks or fires.

Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides, which are pollutants emitted from power plants, industries and automobiles. (Source: EPA official website)

How small is the COVID-19 virus?

How many microns in size is the COVID-19 virus?

The COVID-19 virus is approximately 0.125 Micron or 125 nanometers in diameter.  (Source: National Library of Medicine)

However, it often travels in biological aerosols from coughing and sneezing which range in size from 0.5 - 3 Micron.

Our filtered masks protect you from PM2.5 inhalable particles!

Remember, no mask is 100% effective at protecting from viral transmission.  The most effective thing you can do to stay healthy is wash your hands and practice

appropriate social distancing.

The CDC has recommended we all wear non-medical face masks in public to reduce the spread of the coronavirus (COVID-19).  We are providing you with many different custom options in face mask protection to help you and your family stay safe.
