Xingyan and Shigematsu are also from Japan, but they are far less well-known in China. The reason is that it has a long lack of official purchase channels in Chinese mainland, and its production is low, so its market share is not high, but its reputation in Japan is comparable to that of Shigemamatsu Research Institute. In terms of quality, this protective equipment brand, founded in 1943, has made mask products with excellent protective effects, and has become the designated protective brand of many infectious disease hospitals, biochemical laboratories and asbestos factories in Japan, and most of its products meet the double standards of Japan and the United States.
 
For Chinese consumers, Japanese masks have a natural advantage in terms of fit, as they are designed to target the smaller faces of Asians, and the fit between the hood and the face is much higher than that of larger European and American brands. In the case of Xingyan, the so-called "face-to-face cloth" design was added, that is, additional cotton fabric was added to the contact area between the mask and the bridge of the nose, chin, and cheekbones. Even if the expression changes, it can still fit the face, and the fit is on par with Shigematsu.
 
Xingyan's whole line of products use a bowl-shaped frame design, which expands the breathing space, reduces the feeling of suffocation, and can be folded at will when not in use, which will not be deformed and easy to carry. The Shigematsu DD11V, which also uses a skeleton design, cannot be folded, and is slightly inferior to Xingyan in terms of portability. However, regardless of whether it is head-worn or neck-wearable, the headband of Xingyan's mask is slightly worse in terms of comfort and adjustability, and it is easy to feel tight after wearing it for a long time, which affects comfort.
 
350T is the basic mask of Xingyan, the filter effect of the non-woven material is up to the Japanese DS2 level, which can filter more than 95% of the particles, and the inhalation and exhalation pressures are below 50Pa, reaching the industry-leading level. The 355T has one more exhalation valve than the 350T, and the price is nearly 50% higher, making it suitable for users who have higher requirements for comfort.
 
The 650 series and 350 series are the same DS2 protection class, but the price point is higher, because it uses a wool filter, which about doubles the recommended use time to 20 hours, and the model with an exhalation valve can last up to 25 hours, which is almost the most "long-lasting" mask model on the market today. Compared to the DS2 standard, which can filter more than 95% of particulate matter, the DS1 standard passed by the 550 series only requires more than 80% of particulate matter, but this series is the most expensive mask in Xingyan because it adds activated carbon to the filter element to help absorb odors. However, in some third-party tests, the 550 series masks tend to have a filtration efficiency of more than 90%, so they also have a certain anti-smog effect, and the comfort is similar to that of the 650 and 350 series.
 
In addition to adult masks, Xingyan's children's masks are also well-known to parents for their outstanding protective effects. The Xingyan KIDS series does not follow the Japanese T8151:2005 standard for testing, because there is no special standard for children's particulate matter protective masks in various countries. However, the filtration efficiency mainly depends on the material of the filter element, so manufacturers with certain experience in the production of adult masks can manufacture children's masks with up to the filtration efficiency standard. In children's masks, the judging criteria for passing and excellent depend more on whether there is a fitting design for the child's face shape. In addition, since children's cardiopulmonary function is not as good as that of adults, it is necessary to choose a mask with lower breathing resistance. Parents should also pay attention to how their children feel when wearing a mask, and be sure to take off the mask in time when they have trouble breathing or even dizziness. Children under the age of 3 are not recommended to wear masks.
 
Xingyan's KIDS series is designed for children aged 5 to 12 with three-dimensional cups to better wrap the face, and is equipped with a round cotton elastic band to avoid local tightness caused by the twisting and deformation of the hood, even for more active children, the wearing comfort is very good. In addition, the series has passed BEF (Bacterial Droplet Filtration Efficiency) and VFE (Viral Droplet Filtration Efficiency) tests, where it achieves a filtration efficiency of more than 99%, providing excellent filtration of bacteria and viruses from droplets. Therefore, we believe that the Xingyan KIDS series is the best children's anti-smog mask on the market.
