Want to know about the efficiency level of various masks to decide which one to use in this Covid-19 pandemic? Then, for you here goes our little attempt. Our write up presents you with various types of masks with respective effectiveness in fighting against the Covid-19 germs. Here we go!

Various Masks and their Protection Efficiency

N95 mask

A n95 mask first of all makes it sure that its edges are very close to your face so that not a millimeter of space is left. Being so closely fit to your face, the mask primarily filters out airborne pollutants like dust, fume and mist. 

Most importantly, the mask is highly capable of fighting against the Covid-19 germs by 95%. Besides, it can deal with other pollutants - bacteria, pollen and dust of 0.3 microns by 100%. Moreover, if your n95 mask features a valve inside then it also decreases the exhalation resistance so that you can breathe far easily.   

Kn95 mask

To be straightforward, the efficiency of a Kn95 is almost similar to that of a n95 mask. Yet, there is something to make a differentiation between the two. What are those? Let’s give you a detail:

  • Kn95 mask requires comparatively less strict requirements for pressure drop when you inhale or exhale. 
  • Kn95 mask comes through a mask fit test while the n95 doesn’t. 

Surgical mask

A surgical mask popularly known as face mask unlike n95 or Kn95 features a loose fitting. But, it doesn’t mean that the mask leaves you completely vulnerable to the Covid-19 germs and other pollutants.

Studies show that a face mask is able to kill viruses by 95%. In addition, its efficiency in fighting against the pollutants like pollen, dust and bacteria is 80%. 

FFP1 mask

Just like a surgical mask, an FFP1 also battles against the Covid-19 virus by 95%. And, its efficiency in fighting against the pollutants like pollen, dust and bacteria is also 80%. Then what is the thing that makes FFP1 distinct? 

That thing is the internal leakage rate. An FFP1 mask retains particles by 22% maximum while the rate might be a bit higher with a surgical mask.

Activate carbon mask

If you have been looking for a washable mask that you can use by replacing the filter then activated carbon is the mask for you. But, the unfortunate fact is that its virus killing efficiency is 10% only. In addition, its battling rate against other airborne contaminants is 50%. 

Cloth mask

A cloth mask is made of a piece of cloth that may be of designee but its efficiency against viruses and pollutants is really poor. Although, it can fight back the bacteria, pollen and dust by 50% yet it cannot deal with the Covid-19 virus a bit. 

Sponge mask

The position of a sponge mask in terms of efficiency in fighting back the virus and airborne pollutants is bottomless. The mask can resist the attack of bacteria, pollen and dust by 5% and the attack of virus by 0%. 

Final words

So, these were all about the mostly used everyday masks. Now, the decision is up to you which one you want to pick, for which purpose. But, if you ask our recommendation then that will obviously go for n95, kn95 and surgical mask.
