Is the mask still valid?

June 09, 2021

Many products have a shelf life, such as food, daily chemicals, etc., but did you know that masks also have a shelf life?
The life of the mask actually determines the mask material, technology, user habits and many other aspects.

Fabric: because the mask is directly in contact with the face and mouth, its air permeability, softness, flexibility and durability are the main factors that determine the use time of the mask. There is a direct relationship between the air permeability and the cleanliness of the mask. Only by ensuring the cleanliness of the mask, the mask can play its protective role and will not become a hotbed for bacteria breeding. And good flexibility, can avoid the face and fabric in the friction, produce itching, allergies and other phenomena, to a certain extent, can also extend the mask use time. For the flexibility and durability, it is more important to see whether the shape of the mask remains unchanged.

Disposable Protective Mask

The deformation of a mask means it can't be used, and when it's sleeping.
Science and technology: with the high incidence of haze and other air pollution, the intensity of air pollution is increasing. Now, to extend the service life of masks, we must constantly update and improve from the technical level. This method not only needs to introduce new filter materials, but also needs to improve the mask fitting technology.
In terms of the details of the ear band suture technology, this new mask avoids the traditional mask suture method, and adopts thermal bonding instead. Through hot air bonding, the invention melts the surface of the hot-melt fiber, increases the contact area between the fibers, effectively prevents the ear band from being easy to break, deform and stretch, and improves the service life of the ear band details.
Small details determine success. It is because of such a small and thin lifting cycle that the shelf life of the whole mask is greatly extended.
Usage: if the fabric and technology of a mask reach the excellent level, the shelf life shall be at least 2 years. However, if the use of masks, as well as cleaning and maintenance methods, are not done according to scientific methods, their life will be greatly reduced.
Therefore, the life of the mask depends on the manufacturer's production materials and technology, and also on the user's use and maintenance.
