Mask Evolution
Near at hand
Creative breathing valve structure to increase ventilation and sharply reduce air resistance. For 1180 times of standard pressure test in laboratory, the water pressure did not return to zero for one minute’s time, meeting the standard of excellence.
An independent respiratory area supported by the keel structure, freer breathing without deformation of the inner layer of the mask, smaller air resistance. Aside from the part that touches the face, the mask leaves space between its inner layer and your mouth and nose, reducing the stuffiness, letting you breathe at ease.
A large filtering area formed by the wing-shaped keel structure, capable of continuous filtering for as long as 30 hours.
The silica gel around the keel is 3D designed to fit your facial curve, securing higher tightness while wearing, effectively preventing air leakage and the formation of fog on your glasses.
The inner ring of the mask adopted film-attached elastic fabric fitting tightly to your facial curve; meanwhile, with the taut keel, it forms a perfectly sealed layer allowing no entering air; the housing of the breathing valve is made of PP materials, closely connected to the fabric so as to prevent the entering of air through the space between the valve and the fabric layer when inhaling.
Firmer than gluing, tightness without forming apertures.
No formaldehyde, no secondary pollution.
Fixed by ultrasonic spot welding, undergone laboratory pulling tests: capable of withstanding the pulling force of 80N before falling off.
To fix the band at the back of the head.
