N95 masks are now very rare in the market because of the high demand and the abundance of hoarders, so the price is double the normal price. Now ordinary people are not allowed to wear N95 masks. People who are in good health or asymptomatic are required to wear washable cloth masks and wear them repeatedly.
While the N95 mask should only be worn by physicians and medical personnel treating highly infected patients, including COVID-19 patients. As an important personal protective equipment (PPE) to prevent transmission of the virus, do you know the meaning of the letter ‘N’ and number ‘95’ on the N95 mask?
1.What is N95 mask?
The number '95' is the percentage of how much the mask material can filter out particles. So N95 means 95% filter fine dust 0.3 micron in the air. Thus, N95 filter better than medical masks. However, the N95 mask must wear tight to the face to achieve the desired effect. Therefore, this is also the advantages and disadvantages of this type of mask.
2. Effects of N95 mask
The N95 mask is designed to fit snugly around the nose and mouth of the wearer. When worn correctly, this respirator can prevent at least 95% of the dust and bacteria present in the air.
According to the US Food and Drug Administration (FDA), N95 masks include gas masks. This means that the respirator is specifically designed to protect breathing from particles in very small air.
Meanwhile, the National Institute of Occupational Safety and Health explained that there are several types of disposable masks and N95 masks included in that list. This mask has a protective function by filtering particles in the air when a person breathes, such as bacteria and viruses, including the Corona virus.
This mask is also covered with activated carbon and is designed to fit the mouth area. If worn correctly, the N95 mask will attach firmly to the mouth area, making it difficult to breathe. Therefore, this mask is not recommended for children, the elderly or people with respiratory problems.
