Is the quality of Zhende mask good?

The electrostatic non-woven fabric of Zhende mask can not only block larger dust particles, but also adsorb fine dust by electrostatic attraction due to electrostatic charges attached to its surface, thus achieving higher dust blocking efficiency. However, the thickness of the filter material is very thin, which greatly reduces the user's breathing resistance and makes him feel comfortable.

Zhende medical mask can prevent most pathogens such as bacteria and viruses. WHO recommends that medical personnel use protective masks against particles to prevent virus infection in hospital air, which are mainly divided into medical protective masks, medical surgical masks and general medical masks.
