Are Japanese masks anti-virus?

As long as it conforms to the medical mask or is equivalent to N95, it can prevent virus.

There are three kinds of masks in Japan:

First, dust masks (respirators) are generally related to dust prevention in industrial operations, which has little to do with the topic of this issue, so I will skip it.

The second type is medical masks, which are divided into N95/DS2 and surgical masks. N95 is the standard recognized by NIOS in the United States, and the national standard of Japanese Ministry of Health, Labor and Welfare is DS2, but the standards of different countries are different, and the level is actually the same.

The other one, surgical mask, is basically equivalent to what we mean by medical surgical mask.

please remember this Japanese word サジカルマスク, which is translated from katakana. As long as these words are written on the package, just close your eyes and buy them. Our daily anti-virus is completely adequate.

However, medical masks are basically purchased by medical outlets, and it is difficult to see them in general drugstores, so you can't buy them on a purchasing basis unless there is a special channel to purchase them. Most of the ordinary purchases in drug stores can buy the third kind-family masks, also known as civil masks.

There is a big "Pollen _ Policy" written on the billboard. March and April are the cherry blossom season in Japan, and most masks in Japan are actually in response to the upcoming pollen season. Thanks to this pollen season, the Japanese have actually prepared some masks in stock in advance, otherwise this time it will definitely not stand the shopping raids in the past few days. But after the fifth day, there are basically no masks to scan.

These masks have different functions of preventing colds, hay fever, viruses, PM2.5, etc. If you see the word "_ policy", you will basically know what the mask can protect against.

Generally speaking, what masks are used for and what they can prevent are clearly written on the packaging, so we only need to look at the key words of the packaging to get a general understanding.
