Does KN95 non-medical mask protect against the new coronavirus?

On March 9th, 2020, Wang Yangyang, the attending physician at the Central Hospital of Zaozhuang Mining Group, made a clear answer on whether the KN95 non-medical mask has a protective effect against the new coronavirus.
KN95 non-medical maskThe effect of preventing the new coronavirus infection is still very good, and the protective effect is relatively strong. Although it is not a special medical protective mask, the filtering effect is still very good, and the filtering rate can reach more than 95%.
More than 95% of the visible objects and non-oily particles in the air can be effectively filtered out. KN95 non-medical masks will fit better on the face, and the effect will be more obvious in preventing the infection of the new coronavirus.
After a comprehensive investigation, the protective effect of KN95 non-medical masks is quite outstanding. Under normal circumstances, ordinary people wear disposable medical masks, the protective effect will be better, and the ventilation is better than KN95 non-medical masks. Even better, because the KN95 mask will feel very hot and stuffy after wearing it for too long.

So, KN95 non-medical masks are still very useful for preventing the new coronavirus

  2. Use KN95 non-medical mask against the chin

  3. Pull the ear straps behind the ears and adjust the ear straps to feel as comfortable as possible

  4. Place the fingers of both hands in the middle of the metal nose clip, while pressing inward, move your fingertips along the nose clip to both sides until the nose clip is completely pressed into the shape of the bridge of the nose.
