From the Manufacturer

The anti-breathing film on the top of the mask reduces the fogging of your glasses.

Inside and outside film for double effect

The inner film fills the gap between the face, reducing the amount of breathing from above.

On the other hand, the cause of cloudy glasses is not only a cause of stuffiness from the gaps, but also the breath of removing the mask rises up and makes the glasses cloudy from the outside.

The film on the outside of the mask controls the breath to the underside, reducing the fogging from the outside, and reducing the fogging of your glasses with double inside and out.

EF-K construction

Non-stick, comfortable

The filter is made of breathable material to reduce stuffiness and breathing.

In addition, the resin "space-keeper" located in the center of the mask creates space in your mouth, reducing stickiness, pressure and irritation.

(It is more effective if you put a crease in the center of the space keeper when you wear it.)

With a single twist before installation, this product has improved breath-prevention effect.

(A great way to improve the effectiveness)

By turning the anti-breathing film on the mouth side (the side with the elastic lace) up and attaching it to the bridge of the nose, the gap between the face is easy to fill and further reduce the amount of breathing from the top of the mask.
