Temps: 2020-08-27 Hits: 1

People usually test whether the mask is easy to use from the following aspects:

1.Comfort

These masks are very comfortable on the face. Because the straps on both sides can easily hang on the ears

2.Air leaking

There is very little leaking if the metal nose bridge is properly pinched together.

3.Exercising

Wearing a mask to ride a bike or running is not a problem, and you can breathe

4.Longevity

The mask can last at least a few days of use before losing effectiveness

5.Fog factor

Because of the tight seal around the nose, there is almost no fogging on the glasses.
