Do Masks Have A Shelf Life

There is a shelf life

Masks have a shelf life, which depends on the fabric material, technology, user habits and other factors. The shelf life of disposable masks is generally two years, and it is best to use them within the shelf life. Disposable masks beyond the shelf life are not recommended to be used and should be disinfected as far as possible.

The life of the mask depends on the manufacturer's production materials and technology, and also on the user's use and maintenance mode.

1. Fabric: because the mask is in direct 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. Among them, the air permeability is directly related to the cleanliness of the mask, and only to ensure the cleanliness of the mask, the mask can play its protective role, and will not become a hotbed of germs.

And good flexibility, can avoid the face and fabric friction, pruritus, allergies and other phenomena, to a certain extent, can also extend the use time of the mask. As for the flexibility and durability, it is more related to whether the mask shape remains unchanged.

2. Technology: with the high incidence of haze and other air pollution, the intensity of air pollution is increasing. Now, to improve the life of masks, we must constantly update and improve the technology. This requires not only the introduction of new filter material technology, but also the improvement of the fit between mask and face.

3. Usage habit: if the fabric and technology of a mask reach the excellent level, the shelf life is about 2 years. However, if the use of masks, as well as cleaning and maintenance methods, are not carried out in accordance with scientific methods, its life will be greatly reduced.

In daily life, the most commonly used mask is disposable mask. Disposable mask is made of more than three layers of non-woven fabric, filter paper and carbon cloth containing lead. It is mainly divided into disposable two-layer mask, disposable non-woven mask, disposable three-layer mask and disposable activated carbon mask, which can be used in hospitals, beauty, pharmaceutical, factories, schools and public places.
