Are KN95 masks capable of preventing smog?

Basic requirements for PM2.5.

The filtration efficiency of KN90 grade is 90%, and KN95 grade is 95%, which can be used. Since the actual protection effect obtained by the user mainly depends on the closeness of the mask and the user's face and the actual use time, it is recommended to try several masks, and choose the KN95 mask that has better adhesion, is more comfortable to wear, and is willing to wear. .

3. KN95 mask can be used for one-time hygiene care in ordinary environments, or for blocking or protecting particles other than pathogenic microorganisms such as pollen.

Can a KN95 mask with breathing valve be used?

The exhalation valve has a refined design with several layers of flaps. When inhaled, the valve closes tightly to ensure that no particles enter. When exhaling, the flap opens and allows the warm, moist air to escape. At the same time, a soft flap inside ensures that no small particles enter.

In the last two days there have been many misunderstandings about the KN95 mask with exhalation valve. Some believe that there is no protective effect with an exhalation valve. A 2008-published study specifically investigated whether the exhalation valve interferes with the protection of the wearer. The conclusion is that the presence or absence of an exhalation valve does not affect the wearer's respiratory protection. Simply put, a KN95 mask with an exhalation valve can protect the wearer, but not the people around. If you are a virus carrier, please choose a KN95 mask without an exhalation valve to avoid spreading the virus. If you want to maintain a sterile environment, KN95 masks with exhalation valve cannot be used because the wearer can exhale bacteria or viruses.
