Be careful of yellow sand
Today's news reports that a large scale of yellow dust has occurred in China, and that yellow dust will be scattered over a wide area in Japan from tomorrow the 12th to the 13th.
Suː5 Mask's 5-layer filter cuts 99.9% of 0.1μm particles, including yellow sand and PM2.5 . *Test results at Kaken Test Center
It is very rare for general masks to use two melt-blown sheets of electrostatically charged non-woven fabric . What is important in non-woven masks is actually melt-blown non-woven fabric made only from these ultra-fine fibers .
Suː5 not only has excellent filter performance, but also has a high degree of adhesion (85% adhesion, although there are individual differences), which is one of the major countermeasure effects, so it is a good mask to keep these two points in mind when choosing a mask. I can say that.
If you have allergies such as hay fever, yellow sand may worsen your symptoms, so please be sure to wear a non-woven mask with high filter performance, such as the Suː5 Mask.
