Wikilarge - In addition to cloth and medical masks, recently, masks of the type N95, KN95, or KF94 are being sold. Wearing a quality mask in the right way is one of the main ways to prevent the transmission of Covid-19. Masks can protect someone who has not been infected with the coronavirus while preventing sufferers from spreading the coronavirus and other airborne diseases. Especially in the midst of the spread of the delta variant of the coronavirus which is more easily transmitted and relatively more symptomatic.

In the midst of With the increasing spread of Covid-19, a number of health experts also often call for the public to wear double masks (medical and cloth), or quality masks that can provide higher protection. Especially when someone is forced to leave the house and is in a closed space (indoor), public transportation, or is in a crowd that is difficult to maintain a distance of more than one meter from the people around.

So that you don't get confused anymore, here are the differences between N95, KN95, or KF94 masks that you need to know and tips for safe choosing them.

N95 Mask

Launching CNet, N95 masks are medical masks that can filter aerosol particles up to 95 percent. This mask can filter particles down to 0.3 microns in size. Although the coronavirus particle (SARS-CoV-2) is about 0.1 microns in size, virus particles usually stick to something larger like a droplet. N95 masks are prioritized for health workers or people who stand on the front lines to deal with the Covid-19 outbreak. This high protection mask is designed to be very tight when used. The N95 features an elastic headband and an adjustable metal seal above the nose.

KN95 mask

The KN95 mask is a mask that is claimed to be able to filter aerosol particles up to 95 percent. This mask can be used by the general public, especially when in an environment with a low to moderate risk of transmission. The KN95 mask is designed like a tent, so there is a little air pocket between the nose and the mask. This mask is relatively easier to breathe and less stifling when used. Although it is claimed to have a filtration ability of up to 95 percent, a number of health authorities consider this mask not as effective as an N95 mask. But, apart from being used for health workers or people who are at high risk of facing Covid-19, the public can still benefit from the use of these masks. In fact, KN95 masks are also said to be more protective and practical than ordinary surgical masks or three-layer cloth masks.

KF94 Mask

The KF94 mask is a mask that is claimed to be able to filter aerosol particles up to 94 percent. Like the KN95 mask, the KF94 mask can also be used by the general public, especially when in an environment with a low to moderate risk of transmission. The term "KF" in the KF94 mask stands for "Korean filter" or Korean filter. While the number 94 refers to the level of filtration or filtering of the mask. According to South Korean standards or in their country of origin, this mask can filter 94 percent of particles down to a size of 0.3 microns This mask features an earloop, adjustable wire above the nasal bone, and a tighter side mask. Like the KN95 mask, the KF94 mask is also more protective and practical than ordinary masks or cloth masks.

Tips for choosing a mask that is safe to use

To prevent fake or used masks, make sure you buy N95, KN95, or KF94 masks at a trusted place. For the sake of effectiveness and safety, make sure you buy a mask that has a distribution permit for medical devices from the Ministry of Health. Licensed masks have met the quality requirements for safety and benefits because they have passed the Bacterial Filtration Efficiency (BFE), Partie Filtration Efficiency (PFE), and Breathing Resistance (BR) tests. These quality requirements are used as a guarantee to prevent the transmission of viruses and bacteria as well as harmful micron-sized particles.
