What are the advantages of having a valve on an N95 mask?

N95 respirator 

The N95 respirator is an instance of Personal Protective Equipment (PPE) that has a tight fit to the face of the wearer. The primary objective of the N95 respirator is to guard the wearer against treacherous respiratory droplets, solid particulates, and fine particles. All of these particles are detrimental to the health of the wearer. Therefore, their effect on your body would cause your health to worsen. Therefore, the usage of N95 respirators has become prime after the outbreak of the novel coronavirus.

Various factors like the filtration efficiency, breathability, comfortability, and durability are proof that N95 respirators are more effective than other respirators like surgical masks, cloth masks, and myriads of other types of respirators. 

Advantages of having a valve on an N95 respirator

The function of a valve

The N95 respirators have a tiny piece of plastic that is embedded in the fabric of the respirator. The valve is one-way, which means that the valve closes when the wearer inhales or breathes in. The harmful particulate matter and pathogens do not get through the N95 respirator. However, when you exhale or breathe out, the valve opens. Therefore, the pathogens or viral particles do not get filtered out when the wearer exhales. The valve acts as a doorway in spreading those unfiltered and exhaled particles.

When you wear an N95 respirator with a valve, the majority of the hazardous solid particulates and pathogens are left unfiltered because of the exhalation valve. If you work in a dusty environment, you can wear an N95 respirator with a valve. Similar to that, there are some consequences of wearing an N95 respirator with a valve. The biggest consequence is that it could spread infectious diseases like the novel coronavirus and the influenza virus because of the exhalation valve. 

COVID-19

The novel coronavirus is an infectious and transferable disease that spreads after the infected person interacts with a non-infected individual. It is a respiratory illness that takes more than fourteen days to recover. Some infected individuals might not have to go to the hospital either to recover from this disease. However, a large chunk of people do require to go to the hospital if they start showing serious symptoms like breathing difficulties. Even though the mortality rate of this infectious disease is low, an individual must breathe. In addition to that, you must put on an N95 respirator to keep yourself guarded. 

Consider the wearer has been infected by COVID-19. The wearer could spread this fatal disease if they wear an N95 respirator that has a valve. N95 respirators with a valve do not filter out exhaled airborne particles. Therefore, the viral particles of coronavirus can spread among others if they wear an N95 respirator with a valve. Hence, the usage of N95 respirators without an exhalation valve has been made mandatory. 

Breathability

These N95 respirators are breathable; this means that the wearer does not face any trouble while breathing. Difficulties while breathing could cause various problems to an individual. They might pass out. Therefore, N95 respirators with a valve come into play in this situation. You can use the N95 respirators to facilitate the wearer to breathe. The best places to utilize an N95 respirator with a valve are factories, construction sites, mining sites, and a slew of other dusty places.

Since there is a lot of dust in such places, you can wear N95 respirators; this is because these respirators are efficient at the filtration of particles like dust, dirt, and smog, etc. These respirators filter out dust, and they make it easier for the wearer to breathe since they have an exhalation valve. Therefore, you should wear such respirators in dusty places; this is because of the filtration of dust and dirt particles, and the liberty to fully breathe without facing any breathing difficulties. 

Reduction of sweat

When you wear an N95 respirator with a tight facial fit, the inner surface of your N95 respirator frequently comes in contact with your face; This produces sweat, which causes itchiness on your face. It discomforts the user a lot; this could compel the wearer to take off their N95 respirator. Another reason for the production of a large amount of sweat is breathing. When you wear an N95 respirator without an exhalation valve, the exhaled airborne particles do not get filtered. These exhaled particles accumulate on the face of the wearer; this results in the production of sweat.

However, if you put on an N95 respirator with a valve, your exhaled airborne particles get unfiltered. Therefore, this does not result in the accumulation of airborne particles on your face. Hence, this substantially reduces the amount of sweat on your face. Moreover, the face of the wearer remains cool even though they do not take off their N95 respirator. The heat that builds up between the inner surface of the N95 respirator and your face substantially reduces if you wear an N95 respirator that has a valve. 

If you want to decrease the sweat that occurs as a result of wearing an N95 respirator, you must not run or do activities that require you to run. If you do carry out such activities, you might end up producing a lot of sweat on your face; this would immensely disturb you. You would not be comfortable with wearing an N95 respirator.
