Healthy travel
Under the current environment, if you want to travel healthily, we recommend the use of masks, healthy breathing, and isolation of harmful substances. So for isolation protection, masks that do not use melt blown cloth as filter material have very limited protection effects. Therefore, we chose two layers of filament non-woven fabrics to filter large particles, 25g/m2 thick melt blown cloth to block PM2.5 into equal parts, 0.5μm level protection, for your safety layer. Caring for your breath, PROST supports you. Regarding your safety, PROST guards you.
