Sustained capture performance protects loved ones 24/7.

General non-woven disposable masks that rely on electrostatic charge have lower initial capture efficiency. Prolonged use and/or exposure to moisture in exhaled air further degrades their performance. In contrast, YAMASHIN Filter Mask™ exhibits minimal deterioration in capture performance. It maintains 97% of its performance even after being hand-washed using a pressing motion five times. Instead of relying on static electricity, it relies on its physical structure, a high-density structure with innumerable tiny voids, to capture nano-scale particles.
