N95 masks are now very rare on the market because of very high demand and abundance of hoarders, so the price is twice as high as the normal price. Now ordinary people are not allowed to wear N95 Masks. People with healthy or asymptomatic conditions are required to wear a washable and reusable cloth mask.
While N95 respirators should only be worn by doctors and healthcare workers who treat highly infectious patients, including patients with COVID-19 . As a personal protective equipment (PPE) is very important to prevent virus transmission, do you know the meaning of the letter 'N' and the number '95' on the N95 Mask?
1 What is an N95 mask?
N95 masks are designed to fit snugly around the wearer's nose and mouth. When worn correctly, this mask can block at least 95% of airborne dust and bacteria.
2. The effect of N95 . masks
N95 or N99 means filter 95%, 99% fine dust 0.3 microns in the air. So, N99 mask and N95 filter better medical masks. However, the N95 mask must be worn tightly, covering the face to achieve the desired effect. Therefore, this is also the advantage and disadvantage of this type of mask.

First you need to know in advance what an N95 mask is. According to the US Food and Drug Administration (FDA), N95 respirators include respirators. This means that the Mask is specially designed to protect the breath from very small airborne particles.
Meanwhile, the National Institute for Occupational Safety and Health explains that there are several types of disposable respirators and N95 respirators included in that category. This respirator provides protection by filtering airborne particles when a person breathes, such as bacteria and viruses, including Corona virus.
Disposable respirators are divided into three based on their ability to filter air, hold water and oil. Each code is given N, R or P.
As quoted from Digest Digest, the code 'N' means NOT oil resistant; 'R' means RESISTANT (oil resistant) and 'P' if oil is PROOF (oil resistant). So, the N95 Mask is an Oil Resistant or NOT Oil Resistant Mask.
Meanwhile, the number '95' is the percentage code to how much the mask material can filter out particles. The number '95' means that the respirator is capable of filtering 95 percent of airborne particles. Meanwhile, if the Mask can filter 99 percent of particles, it will be written with the number '99' after the letters.
Therefore, the N95 Mask means the Mask can filter 95% air particles but not oil. This respirator has a filter layer, which can filter 95 percent of particles > 0.3 microns in size so it is effective for filtering viruses for pollutants.
This mask is also covered with activated carbon and is designed to fit snugly around the mouth. If worn correctly, the N95 mask will cling tightly to the mouth area, making it difficult to breathe. Therefore, this mask is not recommended for children, the elderly or people with respiratory problems.
