Elementary molecules are so small that they are difficult to seal. For products to be distributed in the market It was difficult to formulate. However, after many years of research, Hydrogen is generated by the water contained in the exhaled breath We were able to successfully develop a new material. Generates hydrogen equivalent to 3 liters of 1.0 ppm hydrogen water! During the before and after non-woven fabric 4-layer structure with a special 2-layer filter, With a design that matches the shape of the face, It uses a 3D three-dimensional structure that fits perfectly. We paid attention to the smallest parts of the mask. It is safe "Made in Japan". With a high-performance filter with a collection filtration rate of 99%, For measures against influenza, pollen, PM2.5, etc. Pollen collection efficiency (pollen test) 99% Particulate collection efficiency (PFE test) 99% Virus droplet cut (VFE test) 99% Bacterial droplet collection efficiency (BFE test) 99%
