Description

Face Mask Filter - Pack of 10 - PM2.5 Filters - Five Layers, Charcoal Activated Non-woven Fabric For Lung Protection

pack of 10 pm2.5 facemask filter

The CDC (Center for Disease Control) recommends: The Use of Cloth Face Coverings to Help Slow the Spread of COVID-19.

This product is a pack of 10 filters that can be inserted into your cotton masks. Adds value to the filtering properties while in public. This is not a medical device but is part of the recommended face mask protections from the CDC (Center for Disease Control).

The 2.5 indicates the size of particles that are generally absorbed by the filter. Particle size is an important part of understanding how face masks and filtration works.

The face mask function is to prevent droplets. This mask also filters dust, pollen and air pollution. It has filtration to a particles size PM2.5.

Important Note: The PM2.5 filter is not washable. Remove the filter from your mask prior to washing your re-useable masks.

Particle Size Filtration

How Big Are Coronavirus Particles?

The coronavirus particles (referred to as virirons) are spheres with a diameter of approximately .125 microns. The virus has a range of sizes. Coronavirus particles range in size from about .05 microns and up to about .3 microns in diameter which is much smaller than most airborne particles. Scientists have used electron microscopes to measure how big the corona virus is and many have tested filtration to capture the coronavirus particles which are spheres.

particle size of pollution and airborne particles

 

The PM2. 5 name comes from these filters' use as protection against Particulate Matter particle size which is 2.5 microns in diameter, which is the smallest and most dangerous form of air pollution. Airborne virions like the Coronavirus are even smaller than PM2. 5 (the Coronavirus's lipid envelope is about 120 nanometers across).

Can Masks Capture Coronavirus Particles?

The best and most effective filters are the N95 face masks which will filter out most airborne particles from your environment. The N95 mask filters out particles down to a very small .3 micron in diameter. These masks are often used in medical environments because they fit tight to the face and when worn effectively, the mask can filter out 95% of the small corona virus particles.
The filters on this page can capture particles with a diameter size of 2.5 microns (PM2.5). This illustrates the emphasis on the 6 foot distance that is essential for all of us to maintain space as the smallest particles fall to the ground after exhaled. The distance and the mask combine to help increase protection and reduce opportunity for exposures. 3M industrial N95 filters were able to capture over 95% of particles down to 0.007 micron. Given that news outlets have claimed surgical masks can’t capture nano particles, it’s particularly surprising that the simple, 3 layersurgical mask was able to capture 80% of the tiny particles. Surgical masks don’t work as well as N95 masks, but they are cheaper and more readily available. This makes them useful alternatives when other masks aren’t available. Even at moderate levels, particulate matter can be harmful to sensitive people. When air pollution levels are lower, the cardiovascular and respiratory health of a person will be much improved, both long and short term. Masks are an important part of keeping particulate matter out of the lungs.

The corona virus particles (referred to as virirons) are spheres with a diameter of approximately .125 microns. The virus has a range of sizes with the smallest at .06 microns and upt to .14 microns. Scientists have used electron microscopes to measure how big the corona virus is. The airborne particles of the corona-virus that causes COVID-19, called SARS-CoV-2 can stay airborne for up to 3 hours before they fall to the ground. Visually, Corona-virus has a crown-like or corona around it's diameter of pronged protein spike on the surface. Efforts to study live samples of the virus have been ongoing since the outbreak began.
