Pollution, in the modern-day world, has become inevitable. The atmosphere has a lot of impurities present, which are not part of the fresh air human beings consume. Facemasks have been known to play a significant role in filtering the air we breathe in, especially during this COVID-19 pandemic. For this case, let’s compare the Kn95 masks with Cloth masks.
Kn95 VS Cloth masks
A Kn95 mask is a high-quality mask that meets industrial standards. This means that a Kn95 mask has the capability of providing a ninety-five percent filtration rate against dust particles, respiratory droplets, and germs. To make sure that this is effective, it has five layers of protection. On the other hand, a cloth mask’s performance might be less effective since most of them are made from fabrics that are improvised, hence poor filtration.
Despite their ineffectiveness, cloth masks might prevent transmission through contact. They prevent you from touching your cheeks, nose, and mouth. Having it on your face, especially at this time, while fighting the spread of COVID-19, they might as well act as a reminder for not touching your face.
Which materials are these masks made of?
Cloth masks can be made from two materials; fabrics that are tightly woven and fabrics that provide static electricity such as silk. Researchers claim that these two materials may act well in preventing the entry of particles. The Kn95 mask is made of 5 layers. The first layer is made up of woven polypropylene, which serves as a micron dust filter. The second layer is made up of a highly dense filter cloth that also filters micron dust. The third layer consists of an activated carbon filter that gets rid of any unpleasant smell. The fourth layer, just as the second layer, is made up of highly dense filter cloth, and lastly, the fifth layer consists of a non-woven polypropylene that filters missing dust.
Do hospitals recommend these masks?
Kn95 masks are certified masks that are scientifically proven to provide a 95% filtration from germs and respiratory droplets. Hospitals highly recommend kn95 masks since they create a barrier for bacteria, whereas CDC(Centres for Disease Control and Prevention) says that there is no abundant evidence to prove whether the use of cloth masks is effective. Although, if you do not have any other option, especially during this time of the COVID-19 outbreak, the idea of cloth mask is better than nothing. Ideally, combine the use of cloth mask with a face shield that will cover your face thoroughly.
How long do these masks last?
Research has been carried on the Kn95 to see how long they would last. After the study, it was evident that the mask still maintained a 95% filtration rate in 2 days of use, but on the third day, its efficiency declined to 94% filtration rate. This research showed that the mask could not go for more than two days without replacement. Unlike the Kn95, a cloth mask is reusable. It can go for as long as one wishes provided that it is washed after use.
In conclusion, the Kn95 mask is highly recommended since it has a high filtration rate compared to a cloth mask.
