Almost every state in the union has a requirement to wear masks due to the COVID-19 outbreak. The covers are one of the most essential pieces of protection again the possible spread of the coronavirus. This is because of their ability to block the droplets that may contain the virus, when an individual coughs, sneezes or even breathes.
However, what many may not know by now is that by the addition of a filter of some sort, your mask will prove to be even more effective against the virus. If your mask happens to be made of thin, or loosely woven material, a filter is even more crucial.
A study done by the Science and Technology wing of Missouri University showed that a mask made from a bandana would only effectively block 10%-20% of the virus particles, whereas the 90% blocked by an N95 mask.
There is good news—there are items they may be lying around your household that will work for a good filter. It is crucial to keep in mind that it is suggested that the filter material be placed between layers of fabric, as some small fibers that may shed off can be harmful to inhale.
Are commonly found in furnaces, air conditioners, vacuum cleaners, and even air purifiers. HEPA—which stands for High-Efficiency particulate air—filters have been tested to be nearly as effective against blocking the virus as the N-95 masks.
They are not nearly as effective as the material of the mask itself; they are still a viable filter for fabric face masks. By doubling the paper towel layer, studies have shown that the virus-blocking capability can be increased by 33%.
Although coffee filters have been shown to be very effective in the blocking of the virus particles, they have also proved to diminish overall breathability. However, some success has been seen with bagged coffee filters, which has shown to minimalize breathability issues.
