Why KN95 masks are better than surgical or cloth masks

-

What should you look for in a mask? 

A common question about face protection is: What type of mask is best to prevent the contraction and spread of COVID-19?

While there are many types of face protection available such as surgical masks, cloth masks, gaiters, face shields, and bandanas, only a tightly-fit mask with multilayer protection will substantially prevent the contraction or spread of COVID.

A recent study found that an improper fit of the mask can result in over a 60% decrease in the filtration efficiency (1).

Why N95 and KN95 Masks are the best choice

The “95” in the name means that the mask will capture at least 95% of particles .3 microns in size or larger. While the COVID virus is only .1 micron in size, it travels by attaching itself to particulates that are .3 microns or larger, like water droplets, mucus, or dust.

When you consider the tight-fit design of the N95 and KN95, the protection becomes even more reliable. Academic and laboratory studies have consistently determined that wearing this type of mask can reduce your risk of breathing in pathogens by as much as 99% when you account for the snug design in addition to the multilayer filtration.

N95 masks are in short supply and thus recommended for use only in healthcare facilities treating COVID-19 and other infectious diseases. This makes the KN95 your next best option, and it’s readily available to the public.

Where can I find inexpensive KN95 masks? 

We did the research for you and found a reliable supply of KN95 Masks here. They come in multi-packs of different quantities with greater savings when you buy in bulk.

Why you shouldn’t reuse face masks 

Researchers have concluded that COVID can remain active for weeks in small amounts of moisture. It’s even been determined that SARS viruses can, in some cases, multiply in the cells that moisture from the human body contains, amplifying the potential for stagnant moisture from an old mask to infect a human being. That makes it especially important for masks that have collected a significant amount of moisture to be disposed of and replaced.
