Diving masks and polishes are not recommended for the public at present, because they are less effective in protecting against COVID-19 exposure when outdoors. Even when Duke University conducted a study of 14 types of masks, the benefits commonly used by motorcycle users were not effective in filtering out viruses.
Not only that, PT KCI and the COVID-19 Task Force have also started advising passengers not to wear these two types of masks. The reason is that the effectiveness of this type of mask in filtering dust, viruses and bacteria is only 5 percent.
Summarized detikcom, the following are rows of masks that are safe to use to prevent transmission of Corona:
1. N95 mask
The mask that provides more effective protection than other masks is the N95 mask. This receiver type mask can filter large to small particles. As the name implies, this N95 mask can protect up to 95 percent of particles that are very small in size.
Some masks of this type have a valve that makes it easier for the user to breathe. However, the price offered to get this type of mask is very expensive.
2. Surgical masks
This type of mask is also often used to prevent the spread of the virus, namely medical masks or surgical masks. This mask is said to be much better than wearing a diving mask or buff.
Although disposable, this surgical mask can protect the nose and mouth from droplets that contain germs or viruses. In addition, this surgical mask can filter larger particles in the air and provide protection when the supply of N9 masks is insufficient.
3. Cloth mask
One more type of mask that is considered more effective than diving and polishing, namely cloth masks. Usually this cloth mask is made of tightly woven material and consists of 2-3 layers to reduce the spread of COVID-19 droplets.
Quoted from Science alert, when someone improves the drop count increases. This can happen because the material with which the polishing mask breaks down the droplets into smaller particles and can harm the people around them.
