Black Valved Kn95 Respirator Mask Contour Design Reduces Fogging
Description :
1. Three-dimensional tailoring, c-type design: the outer contour fits the shape of the face closely
2. Effective isolation, nose beam design: the bridge of the nose has strong plasticity and can fix both sides of the nose wing that are easy to fall off, with good air tightness and effective isolation from polluted air and dust
3. Flat and wide ear band design: the ear band design is convenient to wear. Wider ear band is adopted to reduce ear pressure and make wearing more comfortable
4. Design of filter breathing valve: the built-in breathing valve reduces respiratory resistance and makes breathing smoother. The aerodynamic design of the valve cover eliminates hot and humid air in time to reduce sultry feeling and avoid bacteria breeding.
