How to test whether the mask is easy to use?

Time: 2020-08-27 Hits: 67

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


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.


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


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.
