N-95 Mask: NOT RESISTANT TO OIL AND FILTERS 95% OF AIRBORNE PARTICLES

3 key factors that each and every mask should have:

  • The respirator must put on correctly and worn during the exposure.

  • The respirator must fit snugly against the user’s face to ensure that there are no gaps between the user’s skin to the respirator seal.

  • The respirator filter must capture more than 95%of the particles from the air that passes through it.


n95 Mask Manufacturer


N: here N stands for Nonoil meaning that if no oil-based particulates are present, then you can use the mask in the work environment.


95:Masks ending in a 95, have 95% efficiency.


Although N-95 is not a mask but a respirator.


N-95 respirator for corona virus is personal protective equipment that totally protects from Airborne particles and liquid contaminating the face.


A face mask can be used to prevent infections and may help protect you against COVID 19 there are 2 types of mask for corona, that are most commonly being used to protect oneself-


1. A surgical or 3 ply mask

2. N95 respirator


A surgical mask is a loose-fitting disposable device that creates a physical barrier betwe3en the mouthy and nose of the wearer and potential contaminant in the immediate environment. If worn properly a surgical mask is meant to help black large particles, droplets, splashes, sprays or splatter that may contain germs.


N95 Respirator is a respiratory protective device designed to achieve a very close facial fit and very close filtration of airborne particles.


The edges of the respirator are designed to form a seal around the nose and mouth.

Basically, the size of corona virus is 0.12 micron but the N-95 mask gives protection from the particles less than the size of 0.03 micron which implies it gives 100% protection at the initial level.

N-95 mask is based on US standards whose filtration rate is 95% with inhalation resistance less than or equal to 343 Pascal.


Its test agent is NaCl with a flow rate of 85 liters/minute.


Each and every mask needs to pass a test known as fit test.


Fit testing is a critical component ton a respiratory protection program whenever works use tight fitting respirators.N-95 requires a seal check each time one is put on.


The structure of N-95 comprises of 4 layers:


Layer 1: It is a non woven with 0.5micron particles protection.


Layer 2: This consists of activated carbon


Layer 3: This is made up of cotton which gives protection from 0.03 micron. So none of the [particle can travel further.


Layer 4: This is similar as the layer 1 but this is only for the comfort.


VALVE: Optimal in nature which reduces breathing resistance during exhalation.


MATERIAL: tough, yet flexible, and non-woven polypropylene fiber.


It can’t be prepared at home as it is automatically designed with a special melt blowing process. This is the only reason that this is one of the most effective mask.


First N-95 mask was made by 3m company in 1972.


In simple words N-95 is as same as a strainer.


A strainer filters particles larger than its opening but smaller than its opening same with the mask, after a certain point, some particles will sneak through.


But this does not happens with N-95 respirator. The particles they filter are generally much smaller than the gaps between the fibers and the mask.


It isn’t like a strainer actually it is much cleverer than a strainer.


The over urging goal of N95 mask is instead to get an air borne particles to touch a fiber in the mask. But once the air borne particles touches the mask it stays stuck to it and doesn’t became airborne again.


It is not like a windowed which doesn’t all9ow insects to enter but it is like a spider web which allow any size of spider to stand. There are many layers which help the particles to stick on.

Centers those who are regulating it are:


a)CDC-center4 for disease control


b)NIOSH- national institute for occupational safety and health


c)OSHA-occupational safety and health administration.



According to quality and experiments top 5 N95 mask are:


1.DETTOL POLLUTION MASK-


It is made up of British military technology and worlds most trusted mask.


2.PURE MC REUSABLE MASK:


It is a 5 layered mask of PM 2.5 filter and each filter with 100 hours filter. this mask is easy to wash.


3.POLLUTION SAFE REUSABLE 4 LAYER MASK-


It is a reusable mask which filters 95% of pollutants with 4 layers of filtration


4.ON ROAD CO REUSABLE MASK:


This one is made in India with ear loop adjustor and dual breathing valves and a stylish and premium design.


5.TDAS ANTI POLLUTION –


It is a reusable mask which can be used for 5-6 months.


A N95 face mask or respirator may offer more protection than regular surgical masks. however the centers for disease control and prevention do not recommend the general public from using this type of a COVID 19 mask outside of healthcare setting.


This is because the supply of N95 respirators is limited and if too many people buy, medical workers, first responders and those who really need them will not have access to the masks, thus putting their health at risk.

So by this we conclude that N95 should be worn by 3 types of people;


1. those who are corona positive that is corona patients.

2. corona suspects.

3. those who are treating corona patients that are doctor nurses and health care workers.


Cotton masks offer little protection against COVID-19. The N95 mask is comprised of microfiber polypropene that has been permanently electrostatic ally charged creating a superior filter

A N95 mask can be reused by allowing it to dry thoroughly. keeping the mask 8in a DRY environment for 3-4 days ensured the virus will not survive.


Cycle through 4 masks in series, one for each day, then repeat.


Hang the mask by a clip and do not let it touch the metal of the oven (which is much hotter and will degrade the mask)


Exposure to UV light will degrade the mask but further4 evaluation of this technique is forthcoming.

Please note: The CDC recommends wearing a cloth face mask in public setting where social distancing measures are difficult to maintain-like at grocery stores and pharmacies.


It is important to emphasize that maintain 6 feet social distancing remains important to slowing the spread of corona virus.


At last don’t forget about SMS that is S-sanitizer; M-mask; S-social distancing.
