The PM2.5 name comes from its original use as protection against Particulate Matter 2.5, some of the smallest and most dangerous forms of air pollution. Airborne virions, such as the Coronavirus, are even smaller than PM2.5
However, research has shown the material to capture nanoparticles of this size with a high degree of efficiency (approx. 95%), and lab tests show a PM2.5 filter with a properly-fitted cloth mask can reduce total airborne particulates by as much as 90%.
Tests show the 5 layers with activated carbon PM2.5 filter filters out about 95% of small airborne pollution (PM2.5).
Our filters are effective at preventing fine particulate matter from bush fires and limiting the inhalation of smoke and dust particles
Activated carbon layer adds additional filtration against unwelcomed organic vapours and odours
The 2.5 in PM2.5 refers to the size of the pollutant in micrometres. Bear with us here while it gets a bit mathematics-y! Micrometres have this symbol: µm and are equivalent to 0.001 millimetres. The smallest thing that the average human eye can perceive is about 0.1 millimetres, which is around the same width as a human hair. So in order for us to see something as incredibly small as a micrometre, we need to use powerful microscopes.
Can be used with any cloth mask.
Highly recommended to get Washable Face Mask available from this website
Insert the PM2.5 filter along the inside of the mask. It Recommends to replace the filter once every 7 days and once every 3 days if the pollution is serious
The best thing you can do to protect your respiratory system from pollutants, viruses, and bacteria is to wear with these filters
Filters are shipped from Albuquerque and New Mexico, United States of America
The USPS offers a range of services covering domestic mail, international mail, and more
